System Overview
AMPCO Model VSI and IVSI are modular prefabricated piping systems which embody flanged joints designed for both quick assembly and pressure-sealing capabilities They offer a combination of insulated piping components as well as the structural accessories needed for support and attachment to building structures Expansion joints are available both in gasket designs and in pressure tight all-welded bellows designs
Standard gas-carrying piping parts are usable for a wide variety of applications
bull Chimneys and stacks for all types of building heating equipmentbull Chimneys for industrial ovens furnaces and processing equipmentbull Exhaust piping for engines or turbine unitsbull Ducting in restaurants for compliance with Type 1 hood requirementsbull Ducting for heated air and combustion productsbull Ducting for light duty pollution control equipmentbull Venting for engine exhaustbull Venting for offshore drilling rigs
Complete Line of Fittings
Model VSI and IVSI are available in eighteen sizes from 5 ID to 48 ID Fittings include various elbows tees supports and terminations as well as a variety of accessory fittings designed to make installation simple and quick
Each component is shipped complete and ready for installation Each ordered part includes Inner Vee Bands Outer Channel Bands and all the necessary hardware
All items included with each order are listed in this catalog under the part description
Thermal Expansion Aspects
The flange-to-flange joints of the Model IVSI inner pipe transmit axial thermal expansion movements and forces in the same manner as continuous welded pipe In addition the expansion of the 300 Series Stainless Steel is approximately 50 greater than that of ordinary low carbon steel and can be estimated as one inch per 100degF rise in gas temperature per 100 (50 at 300degF will expand 15) It is important to calculate this expansion and allow for it by using a suitable Bellows Joint (Part No BJ) or an Adjustable Length (Part No AG) wherever the expansion might exceed 14 This AG fitting which comprises a closely fitting sliding internal section with a graphite packing seal and a sliding outer section can be used to absorb these movement

System Overview
Exceeding the Requirements
AMPCO inventors of the positive pressure system concept far exceeds the requirements of codes and other manufacturers Results of our testing programs illustrate this fact
Leak TestsAMPCO conducted system pressure testing (to 60 wc) against leakage in the presence of UL inspectors Results of these tests are impressive Using the OSHA occupation standard-of-leakage rate of 50 parts per million over an eight hour period as criterion for acceptance the AMPCO system was tested to a leakage rate of only 144 parts per million or three-tenths of one percent (3) of the maximum allowable leakage per UL103 test standard
Seismic TestsWe further demonstrated the superiority of the Model VSI and IVSI concept by conducting seismic load tests These tests proved the structural integrity of our products under severe stress by showing that a guyed stack measuring 20 inches in diameter and exceeding 10 feet above the guying location (installed in strict accordance with the UL103 Listing) could withstand the rigors of all seismic zones
Structural TestsAMPCO recently tested for greater freestanding limits (termination height above a guide point) These tests simulating stack performance under 110 mph wind conditions again demonstrated the superiority of AMPCO products
Skin Temperature Rise TestsA m o n g o t h e r t h i n g s U L 1 0 3 c o v e r s t h e temperature r ise l imi ts of the surrounding combustible materials in an unenclosed chimney installation - and it defines the test set-up to measure the actual temperature rise of those materials at the OEM recommended clearances Our published Model IVSI skin temperatures were obtained during these tests

Product Identification
Ceramic fiber insulation increases the diameter of the outer wallModel VSI 1 air insulation (no ceramic fiber)Model IVSI-C 1 2 and 4 ceramic fiber insulationModel IVSI-Z 3 and 4 dense fiber insulation
(Reference AMPCO installation instructions for the clearance to combustibles for specific applications)
Understanding Product Codes and Part Numbers
All parts manufactured by AMPCO are identified by a series of numbers and letters which describe their makeup and function
Here is how to interpret the Part Number designation for Model VSI and IVSI products
Model VSI vs Model IVSI
1 It begins with the pipe or fittingrsquos internal diameter (in inches) such as 8 22 36 etc
2 This is followed by the Model designation VSI for air-insulated (Model VSI) or IVSI for parts that are fiber insulated (Model IVSIC1 C2 Z3C4 or Z4)
3 Next is the productrsquos Material designation such as 316 or 304304 The first item indicates the makeup of the inner liner while the second half indicates the material content of the outer wall if stainless If aluminized steel outer (Alum) the part number indicates inner material only
(Alternate material and custom outer wall treatments are also
available please contact customer service for information)
4 Then following a long dash the productrsquos Code name is listed such as AG30 JY or MVT If the product is air insulated the product identification ends with this code
(For Product Code listings refer to page 2)
5 Finally when a product is fiber insulated a designation is added at the end to indicate Insulation Thickness C1 means a thickness of 1-inch C2 2-inches Z3 3-inches Z4C4 4 inches
(For comparison see photos above)
Thus the Ordered Part Number for a 30-inch Adjustable Pipe with a 6-inch ID made of 304 Stainless Steel inner and aluminized steel outer packed with 2-inch ceramic fiber insulation is listed
6IVSI304- AG30C2
Note For products with reduction or increaser parts the part number changes as follows
MT and JL - Diameter of Body listed in front of Model VSI or IVSI Diameter of Snout listed in front of Code designation
Example - For a Manifold Tee with a 42 dia Body and 30 dia Snout
42VSI304-30MT
OT and OS - Smaller diameter listed first (before Model designation) Larger diameter listed before Code designation
Example - For a Tapered Increaser with an 8 to 16dia Body

Joint Assembly Parts
For all AMPCO pipe and fittings the flange-to-flange inner pipe joints are identical for each pipe inside diameter
Temperature of gases carried in the system determines the proper sealant used
As shown in the adjoining illustration and photos assembly is accomplished in four easy steps using only standard tools
Step 1Fill Inner Vee Band (VB)
with proper sealant
Step 2Position Inner VB below flange of pipe or fitting
Step 3Mate flanges of two pipes Position Inner VB over both
flanges and tighten
Step 4Position Outer Channel Band
around outer casing Align with pipe grooves and tighten

System Overview
AMPCO Model VSI and IVSI are modular prefabricated piping systems which embody flanged joints designed for both quick assembly and pressure-sealing capabilities They offer a combination of insulated piping components as well as the structural accessories needed for support and attachment to building structures Expansion joints are available both in gasket designs and in pressure tight all-welded bellows designs
Standard gas-carrying piping parts are usable for a wide variety of applications
bull Chimneys and stacks for all types of building heating equipmentbull Chimneys for industrial ovens furnaces and processing equipmentbull Exhaust piping for engines or turbine unitsbull Ducting in restaurants for compliance with Type 1 hood requirementsbull Ducting for heated air and combustion productsbull Ducting for light duty pollution control equipmentbull Venting for engine exhaustbull Venting for offshore drilling rigs
Complete Line of Fittings
Model VSI and IVSI are available in eighteen sizes from 5 ID to 48 ID Fittings include various elbows tees supports and terminations as well as a variety of accessory fittings designed to make installation simple and quick
Each component is shipped complete and ready for installation Each ordered part includes Inner Vee Bands Outer Channel Bands and all the necessary hardware
All items included with each order are listed in this catalog under the part description
Thermal Expansion Aspects
The flange-to-flange joints of the Model IVSI inner pipe transmit axial thermal expansion movements and forces in the same manner as continuous welded pipe In addition the expansion of the 300 Series Stainless Steel is approximately 50 greater than that of ordinary low carbon steel and can be estimated as one inch per 100degF rise in gas temperature per 100 (50 at 300degF will expand 15) It is important to calculate this expansion and allow for it by using a suitable Bellows Joint (Part No BJ) or an Adjustable Length (Part No AG) wherever the expansion might exceed 14 This AG fitting which comprises a closely fitting sliding internal section with a graphite packing seal and a sliding outer section can be used to absorb these movement

System Overview
Exceeding the Requirements
AMPCO inventors of the positive pressure system concept far exceeds the requirements of codes and other manufacturers Results of our testing programs illustrate this fact
Leak TestsAMPCO conducted system pressure testing (to 60 wc) against leakage in the presence of UL inspectors Results of these tests are impressive Using the OSHA occupation standard-of-leakage rate of 50 parts per million over an eight hour period as criterion for acceptance the AMPCO system was tested to a leakage rate of only 144 parts per million or three-tenths of one percent (3) of the maximum allowable leakage per UL103 test standard
Seismic TestsWe further demonstrated the superiority of the Model VSI and IVSI concept by conducting seismic load tests These tests proved the structural integrity of our products under severe stress by showing that a guyed stack measuring 20 inches in diameter and exceeding 10 feet above the guying location (installed in strict accordance with the UL103 Listing) could withstand the rigors of all seismic zones
Structural TestsAMPCO recently tested for greater freestanding limits (termination height above a guide point) These tests simulating stack performance under 110 mph wind conditions again demonstrated the superiority of AMPCO products
Skin Temperature Rise TestsA m o n g o t h e r t h i n g s U L 1 0 3 c o v e r s t h e temperature r ise l imi ts of the surrounding combustible materials in an unenclosed chimney installation - and it defines the test set-up to measure the actual temperature rise of those materials at the OEM recommended clearances Our published Model IVSI skin temperatures were obtained during these tests

Product Identification
Ceramic fiber insulation increases the diameter of the outer wallModel VSI 1 air insulation (no ceramic fiber)Model IVSI-C 1 2 and 4 ceramic fiber insulationModel IVSI-Z 3 and 4 dense fiber insulation
(Reference AMPCO installation instructions for the clearance to combustibles for specific applications)
Understanding Product Codes and Part Numbers
All parts manufactured by AMPCO are identified by a series of numbers and letters which describe their makeup and function
Here is how to interpret the Part Number designation for Model VSI and IVSI products
Model VSI vs Model IVSI
1 It begins with the pipe or fittingrsquos internal diameter (in inches) such as 8 22 36 etc
2 This is followed by the Model designation VSI for air-insulated (Model VSI) or IVSI for parts that are fiber insulated (Model IVSIC1 C2 Z3C4 or Z4)
3 Next is the productrsquos Material designation such as 316 or 304304 The first item indicates the makeup of the inner liner while the second half indicates the material content of the outer wall if stainless If aluminized steel outer (Alum) the part number indicates inner material only
(Alternate material and custom outer wall treatments are also
available please contact customer service for information)
4 Then following a long dash the productrsquos Code name is listed such as AG30 JY or MVT If the product is air insulated the product identification ends with this code
(For Product Code listings refer to page 2)
5 Finally when a product is fiber insulated a designation is added at the end to indicate Insulation Thickness C1 means a thickness of 1-inch C2 2-inches Z3 3-inches Z4C4 4 inches
(For comparison see photos above)
Thus the Ordered Part Number for a 30-inch Adjustable Pipe with a 6-inch ID made of 304 Stainless Steel inner and aluminized steel outer packed with 2-inch ceramic fiber insulation is listed
6IVSI304- AG30C2
Note For products with reduction or increaser parts the part number changes as follows
MT and JL - Diameter of Body listed in front of Model VSI or IVSI Diameter of Snout listed in front of Code designation
Example - For a Manifold Tee with a 42 dia Body and 30 dia Snout
42VSI304-30MT
OT and OS - Smaller diameter listed first (before Model designation) Larger diameter listed before Code designation
Example - For a Tapered Increaser with an 8 to 16dia Body

Joint Assembly Parts
For all AMPCO pipe and fittings the flange-to-flange inner pipe joints are identical for each pipe inside diameter
Temperature of gases carried in the system determines the proper sealant used
As shown in the adjoining illustration and photos assembly is accomplished in four easy steps using only standard tools
Step 1Fill Inner Vee Band (VB)
with proper sealant
Step 2Position Inner VB below flange of pipe or fitting
Step 3Mate flanges of two pipes Position Inner VB over both
flanges and tighten
Step 4Position Outer Channel Band
around outer casing Align with pipe grooves and tighten
Illustrations shown are for reference onlySee Installation Instructions for detailed sealant application and use

System Overview
AMPCO Model VSI and IVSI are modular prefabricated piping systems which embody flanged joints designed for both quick assembly and pressure-sealing capabilities They offer a combination of insulated piping components as well as the structural accessories needed for support and attachment to building structures Expansion joints are available both in gasket designs and in pressure tight all-welded bellows designs
Standard gas-carrying piping parts are usable for a wide variety of applications
bull Chimneys and stacks for all types of building heating equipmentbull Chimneys for industrial ovens furnaces and processing equipmentbull Exhaust piping for engines or turbine unitsbull Ducting in restaurants for compliance with Type 1 hood requirementsbull Ducting for heated air and combustion productsbull Ducting for light duty pollution control equipmentbull Venting for engine exhaustbull Venting for offshore drilling rigs
Complete Line of Fittings
Model VSI and IVSI are available in eighteen sizes from 5 ID to 48 ID Fittings include various elbows tees supports and terminations as well as a variety of accessory fittings designed to make installation simple and quick
Each component is shipped complete and ready for installation Each ordered part includes Inner Vee Bands Outer Channel Bands and all the necessary hardware
All items included with each order are listed in this catalog under the part description
Thermal Expansion Aspects
The flange-to-flange joints of the Model IVSI inner pipe transmit axial thermal expansion movements and forces in the same manner as continuous welded pipe In addition the expansion of the 300 Series Stainless Steel is approximately 50 greater than that of ordinary low carbon steel and can be estimated as one inch per 100degF rise in gas temperature per 100 (50 at 300degF will expand 15) It is important to calculate this expansion and allow for it by using a suitable Bellows Joint (Part No BJ) or an Adjustable Length (Part No AG) wherever the expansion might exceed 14 This AG fitting which comprises a closely fitting sliding internal section with a graphite packing seal and a sliding outer section can be used to absorb these movement

System Overview
Exceeding the Requirements
AMPCO inventors of the positive pressure system concept far exceeds the requirements of codes and other manufacturers Results of our testing programs illustrate this fact
Leak TestsAMPCO conducted system pressure testing (to 60 wc) against leakage in the presence of UL inspectors Results of these tests are impressive Using the OSHA occupation standard-of-leakage rate of 50 parts per million over an eight hour period as criterion for acceptance the AMPCO system was tested to a leakage rate of only 144 parts per million or three-tenths of one percent (3) of the maximum allowable leakage per UL103 test standard
Seismic TestsWe further demonstrated the superiority of the Model VSI and IVSI concept by conducting seismic load tests These tests proved the structural integrity of our products under severe stress by showing that a guyed stack measuring 20 inches in diameter and exceeding 10 feet above the guying location (installed in strict accordance with the UL103 Listing) could withstand the rigors of all seismic zones
Structural TestsAMPCO recently tested for greater freestanding limits (termination height above a guide point) These tests simulating stack performance under 110 mph wind conditions again demonstrated the superiority of AMPCO products
Skin Temperature Rise TestsA m o n g o t h e r t h i n g s U L 1 0 3 c o v e r s t h e temperature r ise l imi ts of the surrounding combustible materials in an unenclosed chimney installation - and it defines the test set-up to measure the actual temperature rise of those materials at the OEM recommended clearances Our published Model IVSI skin temperatures were obtained during these tests

Product Identification
Ceramic fiber insulation increases the diameter of the outer wallModel VSI 1 air insulation (no ceramic fiber)Model IVSI-C 1 2 and 4 ceramic fiber insulationModel IVSI-Z 3 and 4 dense fiber insulation
(Reference AMPCO installation instructions for the clearance to combustibles for specific applications)
Understanding Product Codes and Part Numbers
All parts manufactured by AMPCO are identified by a series of numbers and letters which describe their makeup and function
Here is how to interpret the Part Number designation for Model VSI and IVSI products
Model VSI vs Model IVSI
1 It begins with the pipe or fittingrsquos internal diameter (in inches) such as 8 22 36 etc
2 This is followed by the Model designation VSI for air-insulated (Model VSI) or IVSI for parts that are fiber insulated (Model IVSIC1 C2 Z3C4 or Z4)
3 Next is the productrsquos Material designation such as 316 or 304304 The first item indicates the makeup of the inner liner while the second half indicates the material content of the outer wall if stainless If aluminized steel outer (Alum) the part number indicates inner material only
(Alternate material and custom outer wall treatments are also
available please contact customer service for information)
4 Then following a long dash the productrsquos Code name is listed such as AG30 JY or MVT If the product is air insulated the product identification ends with this code
(For Product Code listings refer to page 2)
5 Finally when a product is fiber insulated a designation is added at the end to indicate Insulation Thickness C1 means a thickness of 1-inch C2 2-inches Z3 3-inches Z4C4 4 inches
(For comparison see photos above)
Thus the Ordered Part Number for a 30-inch Adjustable Pipe with a 6-inch ID made of 304 Stainless Steel inner and aluminized steel outer packed with 2-inch ceramic fiber insulation is listed
6IVSI304- AG30C2
Note For products with reduction or increaser parts the part number changes as follows
MT and JL - Diameter of Body listed in front of Model VSI or IVSI Diameter of Snout listed in front of Code designation
Example - For a Manifold Tee with a 42 dia Body and 30 dia Snout
42VSI304-30MT
OT and OS - Smaller diameter listed first (before Model designation) Larger diameter listed before Code designation
Example - For a Tapered Increaser with an 8 to 16dia Body

Joint Assembly Parts
For all AMPCO pipe and fittings the flange-to-flange inner pipe joints are identical for each pipe inside diameter
Temperature of gases carried in the system determines the proper sealant used
As shown in the adjoining illustration and photos assembly is accomplished in four easy steps using only standard tools
Step 1Fill Inner Vee Band (VB)
with proper sealant
Step 2Position Inner VB below flange of pipe or fitting
Step 3Mate flanges of two pipes Position Inner VB over both
flanges and tighten
Step 4Position Outer Channel Band
around outer casing Align with pipe grooves and tighten

System Overview
Exceeding the Requirements
AMPCO inventors of the positive pressure system concept far exceeds the requirements of codes and other manufacturers Results of our testing programs illustrate this fact
Leak TestsAMPCO conducted system pressure testing (to 60 wc) against leakage in the presence of UL inspectors Results of these tests are impressive Using the OSHA occupation standard-of-leakage rate of 50 parts per million over an eight hour period as criterion for acceptance the AMPCO system was tested to a leakage rate of only 144 parts per million or three-tenths of one percent (3) of the maximum allowable leakage per UL103 test standard
Seismic TestsWe further demonstrated the superiority of the Model VSI and IVSI concept by conducting seismic load tests These tests proved the structural integrity of our products under severe stress by showing that a guyed stack measuring 20 inches in diameter and exceeding 10 feet above the guying location (installed in strict accordance with the UL103 Listing) could withstand the rigors of all seismic zones
Structural TestsAMPCO recently tested for greater freestanding limits (termination height above a guide point) These tests simulating stack performance under 110 mph wind conditions again demonstrated the superiority of AMPCO products
Skin Temperature Rise TestsA m o n g o t h e r t h i n g s U L 1 0 3 c o v e r s t h e temperature r ise l imi ts of the surrounding combustible materials in an unenclosed chimney installation - and it defines the test set-up to measure the actual temperature rise of those materials at the OEM recommended clearances Our published Model IVSI skin temperatures were obtained during these tests

Product Identification
Ceramic fiber insulation increases the diameter of the outer wallModel VSI 1 air insulation (no ceramic fiber)Model IVSI-C 1 2 and 4 ceramic fiber insulationModel IVSI-Z 3 and 4 dense fiber insulation
(Reference AMPCO installation instructions for the clearance to combustibles for specific applications)
Understanding Product Codes and Part Numbers
All parts manufactured by AMPCO are identified by a series of numbers and letters which describe their makeup and function
Here is how to interpret the Part Number designation for Model VSI and IVSI products
Model VSI vs Model IVSI
1 It begins with the pipe or fittingrsquos internal diameter (in inches) such as 8 22 36 etc
2 This is followed by the Model designation VSI for air-insulated (Model VSI) or IVSI for parts that are fiber insulated (Model IVSIC1 C2 Z3C4 or Z4)
3 Next is the productrsquos Material designation such as 316 or 304304 The first item indicates the makeup of the inner liner while the second half indicates the material content of the outer wall if stainless If aluminized steel outer (Alum) the part number indicates inner material only
(Alternate material and custom outer wall treatments are also
available please contact customer service for information)
4 Then following a long dash the productrsquos Code name is listed such as AG30 JY or MVT If the product is air insulated the product identification ends with this code
(For Product Code listings refer to page 2)
5 Finally when a product is fiber insulated a designation is added at the end to indicate Insulation Thickness C1 means a thickness of 1-inch C2 2-inches Z3 3-inches Z4C4 4 inches
(For comparison see photos above)
Thus the Ordered Part Number for a 30-inch Adjustable Pipe with a 6-inch ID made of 304 Stainless Steel inner and aluminized steel outer packed with 2-inch ceramic fiber insulation is listed
6IVSI304- AG30C2
Note For products with reduction or increaser parts the part number changes as follows
MT and JL - Diameter of Body listed in front of Model VSI or IVSI Diameter of Snout listed in front of Code designation
Example - For a Manifold Tee with a 42 dia Body and 30 dia Snout
42VSI304-30MT
OT and OS - Smaller diameter listed first (before Model designation) Larger diameter listed before Code designation
Example - For a Tapered Increaser with an 8 to 16dia Body

Joint Assembly Parts
For all AMPCO pipe and fittings the flange-to-flange inner pipe joints are identical for each pipe inside diameter
Temperature of gases carried in the system determines the proper sealant used
As shown in the adjoining illustration and photos assembly is accomplished in four easy steps using only standard tools
Step 1Fill Inner Vee Band (VB)
with proper sealant
Step 2Position Inner VB below flange of pipe or fitting
Step 3Mate flanges of two pipes Position Inner VB over both
flanges and tighten
Step 4Position Outer Channel Band
around outer casing Align with pipe grooves and tighten

Product Identification
Ceramic fiber insulation increases the diameter of the outer wallModel VSI 1 air insulation (no ceramic fiber)Model IVSI-C 1 2 and 4 ceramic fiber insulationModel IVSI-Z 3 and 4 dense fiber insulation
(Reference AMPCO installation instructions for the clearance to combustibles for specific applications)
Understanding Product Codes and Part Numbers
All parts manufactured by AMPCO are identified by a series of numbers and letters which describe their makeup and function
Here is how to interpret the Part Number designation for Model VSI and IVSI products
Model VSI vs Model IVSI
1 It begins with the pipe or fittingrsquos internal diameter (in inches) such as 8 22 36 etc
2 This is followed by the Model designation VSI for air-insulated (Model VSI) or IVSI for parts that are fiber insulated (Model IVSIC1 C2 Z3C4 or Z4)
3 Next is the productrsquos Material designation such as 316 or 304304 The first item indicates the makeup of the inner liner while the second half indicates the material content of the outer wall if stainless If aluminized steel outer (Alum) the part number indicates inner material only
(Alternate material and custom outer wall treatments are also
available please contact customer service for information)
4 Then following a long dash the productrsquos Code name is listed such as AG30 JY or MVT If the product is air insulated the product identification ends with this code
(For Product Code listings refer to page 2)
5 Finally when a product is fiber insulated a designation is added at the end to indicate Insulation Thickness C1 means a thickness of 1-inch C2 2-inches Z3 3-inches Z4C4 4 inches
(For comparison see photos above)
Thus the Ordered Part Number for a 30-inch Adjustable Pipe with a 6-inch ID made of 304 Stainless Steel inner and aluminized steel outer packed with 2-inch ceramic fiber insulation is listed
6IVSI304- AG30C2
Note For products with reduction or increaser parts the part number changes as follows
MT and JL - Diameter of Body listed in front of Model VSI or IVSI Diameter of Snout listed in front of Code designation
Example - For a Manifold Tee with a 42 dia Body and 30 dia Snout
42VSI304-30MT
OT and OS - Smaller diameter listed first (before Model designation) Larger diameter listed before Code designation
Example - For a Tapered Increaser with an 8 to 16dia Body

Joint Assembly Parts
For all AMPCO pipe and fittings the flange-to-flange inner pipe joints are identical for each pipe inside diameter
Temperature of gases carried in the system determines the proper sealant used
As shown in the adjoining illustration and photos assembly is accomplished in four easy steps using only standard tools
Step 1Fill Inner Vee Band (VB)
with proper sealant
Step 2Position Inner VB below flange of pipe or fitting
Step 3Mate flanges of two pipes Position Inner VB over both
flanges and tighten
Step 4Position Outer Channel Band
around outer casing Align with pipe grooves and tighten

Product Identification
Ceramic fiber insulation increases the diameter of the outer wallModel VSI 1 air insulation (no ceramic fiber)Model IVSI-C 1 2 and 4 ceramic fiber insulationModel IVSI-Z 3 and 4 dense fiber insulation
(Reference AMPCO installation instructions for the clearance to combustibles for specific applications)
Understanding Product Codes and Part Numbers
All parts manufactured by AMPCO are identified by a series of numbers and letters which describe their makeup and function
Here is how to interpret the Part Number designation for Model VSI and IVSI products
Model VSI vs Model IVSI
1 It begins with the pipe or fittingrsquos internal diameter (in inches) such as 8 22 36 etc
2 This is followed by the Model designation VSI for air-insulated (Model VSI) or IVSI for parts that are fiber insulated (Model IVSIC1 C2 Z3C4 or Z4)
3 Next is the productrsquos Material designation such as 316 or 304304 The first item indicates the makeup of the inner liner while the second half indicates the material content of the outer wall if stainless If aluminized steel outer (Alum) the part number indicates inner material only
(Alternate material and custom outer wall treatments are also
available please contact customer service for information)
4 Then following a long dash the productrsquos Code name is listed such as AG30 JY or MVT If the product is air insulated the product identification ends with this code
(For Product Code listings refer to page 2)
5 Finally when a product is fiber insulated a designation is added at the end to indicate Insulation Thickness C1 means a thickness of 1-inch C2 2-inches Z3 3-inches Z4C4 4 inches
(For comparison see photos above)
Thus the Ordered Part Number for a 30-inch Adjustable Pipe with a 6-inch ID made of 304 Stainless Steel inner and aluminized steel outer packed with 2-inch ceramic fiber insulation is listed
6IVSI304- AG30C2
Note For products with reduction or increaser parts the part number changes as follows
MT and JL - Diameter of Body listed in front of Model VSI or IVSI Diameter of Snout listed in front of Code designation
Example - For a Manifold Tee with a 42 dia Body and 30 dia Snout
42VSI304-30MT
OT and OS - Smaller diameter listed first (before Model designation) Larger diameter listed before Code designation
Example - For a Tapered Increaser with an 8 to 16dia Body

Joint Assembly Parts
For all AMPCO pipe and fittings the flange-to-flange inner pipe joints are identical for each pipe inside diameter
Temperature of gases carried in the system determines the proper sealant used
As shown in the adjoining illustration and photos assembly is accomplished in four easy steps using only standard tools
Step 1Fill Inner Vee Band (VB)
with proper sealant
Step 2Position Inner VB below flange of pipe or fitting
Step 3Mate flanges of two pipes Position Inner VB over both
flanges and tighten
Step 4Position Outer Channel Band
around outer casing Align with pipe grooves and tighten

Joint Assembly Parts
For all AMPCO pipe and fittings the flange-to-flange inner pipe joints are identical for each pipe inside diameter
Temperature of gases carried in the system determines the proper sealant used
As shown in the adjoining illustration and photos assembly is accomplished in four easy steps using only standard tools
Step 1Fill Inner Vee Band (VB)
with proper sealant
Step 2Position Inner VB below flange of pipe or fitting
Step 3Mate flanges of two pipes Position Inner VB over both
flanges and tighten
Step 4Position Outer Channel Band
around outer casing Align with pipe grooves and tighten
Illustrations shown are for reference onlySee Installation Instructions for detailed sealant application and use

Joint Assembly Parts
For all AMPCO pipe and fittings the flange-to-flange inner pipe joints are identical for each pipe inside diameter
Temperature of gases carried in the system determines the proper sealant used
As shown in the adjoining illustration and photos assembly is accomplished in four easy steps using only standard tools
Step 1Fill Inner Vee Band (VB)
with proper sealant
Step 2Position Inner VB below flange of pipe or fitting
Step 3Mate flanges of two pipes Position Inner VB over both
flanges and tighten
Step 4Position Outer Channel Band
around outer casing Align with pipe grooves and tighten
Illustrations shown are for reference onlySee Installation Instructions for detailed sealant application and use
