FLEXIBLE COUPLINGSARGCO flexible couplings allow for full design features in applications such as curved or deflected layouts and or when systems are exposed to outside forces beyond normal static conditions such as seismic events or where vibra-tion and or noise attenuation are a concern. The ability to design in controlled flexibility is an advantageous feature when compared to traditional rigid joining methods such as threading, flanging and welding. When designing with flexible couplings you must allow for proper support to the system so as to eliminate undesired stress.There are several published standards and codes covering grooved piping component. These codes or standards may vary as to the definition or standard for flexible couplings. System designers should confirm which standard(s) and or code(s) are required for the system being designed and they should select the applicable coupling for the application.

RIGID or FLEXIBLE? ARGCO grooved couplings are classified into two types, flexible and rigid. The following information is intended for system designers and installers to better understand the nature of the grooved piping systems. This will allow the designer and installer to make better use of the design features and advantages of grooved piping components and systems
RIGID COUPLINGSARGCO rigid couplings can be used in application where you re-quire a rigid joint similar to that of a traditional flanged, welded and or threaded connection. You need not worry about the snak-ing of the pipe on straight runs, as all ARGCO rigid couplings uti-lize both a mechanical and frictional interlock design to provide rigidity. Rigid couplings eliminate or reduce undesired angular movement, axial displacement and rotation after installation as is required under normal service conditions. Rigid couplings are some of the most popular and most widely used today.
ANGLE-PAD DESIGNAngle-pad design: As the bolts are tightened, the angled bolt pads slide in opposite directions causing the couplings keys to ghtly grip the pipe, while at the same me the pipe grooves are forced outward against the coupling keys.
T&G design: The T&G (tongue & groove) mechanism provides a mechanical and frictional interlock resulting in a rigid joint which reduces undesired angular movement. ARGCO precision casting techniques allow the couplingsegments to meet metal-to-metal when installed on properly grooved pipe.

DESIGN FEATURESDesigners and installers should designtheir fire protection systems in compliancewith this standard.
NFPA 13 defines a FLEXIBLE COUPLING as;“a listed coupling or fitting that allows axial displacement,rotation, and at least 1 degree of angular movement of the pipe without inducing harm on the pipe. For pipe diameters of 8 in. and larger, the angular movement shall be permitted to be less than 1 degree but not less than 0.5 degrees.” (NFPA 13-2007 3.5.4)For sprinkler systems, NFPA 13 specifies the use of flexible cou-plings to protect the system against damage from earthquakes and sets some specific examples of how and where they should be used.

materials include 2205 Duplex, 2507 Super Duplex and ASTM CK-3MCuN (UNSJ93245), equivalent to 254SMO*.(* 254SMO is a registered trademark of Avesta Polarit AQB.)
Lede gaskets are available in a variety of congura�ons and compounds to meet your specic requirements. These gaskets have excellent self sealing capabili�es and
are designed to provide a leak �ght seal. During assembly the gasket is rst stretched over the pipe ends which forms the ini�al seal. As the housing segments are installed and secured the pressure responsive gasket is slightly compressed to form a leak-�ght joint. The strength of the seal is further enhanced by internal line pressure that creates downward pressure on the lips of the gasket. The gasket also seals well under vacuum condi�ons up to 10 inHg (254 mmHg) which may occur when a system is drained. Please refer to the Lede Gasket Selec�on Guide for addi�onal details and gasket materials.
Lede products u�lize oval neck track bolts and heavy duty hex nuts, available either in UNC threaded or ISO metric threaded. The oval neck track bolts mate into the oval holes in the housing segments to allow for easy �ghtening using only a single wrench/spanner. The UNC bolts and nuts are electro zinc plated in a silver chromate color and ISO bolts and nuts in a gold chromate color. Hot-dip galvanized bolts and nuts are also available upon request.

DATA CHART NOTES
Nominal Size: ARGCO couplings and fittings are identified by the nominal IPS pipe size in inches or nominal diameter of pipe (DN) in millimeters.
Pipe OD: Actual outside diameter of pipe in inches and millimeters.Maximum Working Pressure: Maximum working pressures listed are CWP (cold water pressure) or maximum allowed working pressure within the service temperature range of the gasket used in the coupling, based on standard wall or sch. 7/10/40 steel pipe, cut or roll-grooved to ANSI/AWWA C606-04 specifications. These ranges may occasionally differ from maximum working pressures listed and/or approved by UL, ULC, and/or FM as testing conditions and test pipes differ. For performance data on other pipe schedules contact ARGCO.Note: For one time field test only the maximum joint working pressure may be increased 1.5 times the figures shownMaximum End Load: Maximum end loads listed are total of internal and external forces to which the joint can be subjected, based on standard wall or sch. 7/10/40 steel pipe, cut or roll-grooved to ANSI/AWWA C606-04 specifications.Axial Displacement: Designed range of the gap between pipe ends based on roll grooved pipe.Angular Movement (Deflection): Maximum allowable deflection of pipe from centerline when the joint is used with cut or roll-grooved steel pipe under no internal pressure.Dimensions: “A”, “B”, “C” and so on are external dimensions for reference purpose only in millimeters and inchesBolt Size: UNC bolt size and length in inches and ISO metric bolt size and length in millimeters with numbers of bolts where ap-plicable.Bolt Torque: Recommended bolt fastening torque in Lbs-Ft and N-m.
GENERAL NOTES
Service Fluid and Temperature: Service fluid and temperature limitations for ARGCO couplings are primarily governed by the gasket used within the coupling. Always refer to and consult the ARGCO Gasket Selection Guide.
Working Pressure: ARGCO grooved couplings are generally engineered for use with standard or sch. 7/10/40 steel pipes (except for some high pressure models) and can be used within the rated working pressures as shown in the ARGCO literature. A one me only field test at 1.5 times the working pressure is allowed.
As there are limitations in service temperatures, the ARGCO couplings and fittings do not adopt the ANSI temperature- pressure ranges (Class 150, Class 300, etc.), ISO or JIS methods of pressure ranges (PN10, PN16, JIS 10K or 20K, etc.). All the published work-ing pressures are CWP, non-shock cold water pressures, unless otherwise specified. Actual allowed working pressures for a specific coupling will vary depending on the coupling size, pipe material, pipe schedule (or thickness) and types of grooves used. Special attention is required when using thin wall stainless steel pipe such as sch. 5. For further details request the performance data for specific thin wall pipe.The dimensions, weights, performance data, and other specifications shown in this catalog supersede all previous published data.

The ARGCO Model 101 is an angle-pad design standard rigid coupling for moderate pressure piping services including fire mains, long straight runs and value connections. The angle-pad design allows the coupling housings to slide along the bolt pads when tightened. The result is an offset clamping action which provides a rigid joint which resistsso-called ‘snaking’ of a long straight run. Support andhanging requirements correspond to ANSI B31.1, B31.9 and NFPA 13. With the removal of only one bolt you can make a fast and easy ‘swing-over’ installation.

INSTALLATION INSTRUCTIONS:
STANDARD RIGID COUPLINGDepressurize and drain the piping system before attemptingto install, remove, or adjust any piping products.Wear safety glasses, hard hat, and foot protection.
1. CHECK PIPE ENDS:The outside surface of the pipe from the pipe end to the groovemust be smooth and free from indentations, projections(including weld seams), and roll marks to ensure a leaktightseal for the gasket. All oil, grease, loose paint, and dirt mustbe removed.
2. CHECK GASKET AND LUBRICATE :Check the gasket to make sure it is suitable for the intendedservice. Apply a thin coat of Tuf-Lube Gasket GreaseLubricant to the gasket lips and exterior.
3. POSITION GASKET:Position the gasket over the pipe end. Make sure the gasket does not overhang the pipe end.
4. JOIN PIPE ENDS:Align and bring the two pipe ends together. Slide the gasket into position, and make sure it is centered between the grooves in each pipe.Make sure no portion of the gasket extends into the groove in either pipe.
5. ASSEMBLE HOUSINGS:Insert one bolt into the housings, and thread the nut loosely onto the bolt (nut should be flush with end of bolt) .
6. INSTALL HOUSINGS:Install the housings over the gasket. Make sure the housings’ keys engage the grooves properly on both pipes.
Torque ValueWhen a torque value is specified for coupling installation, this torque MUST be applied to the nuts in order to achieve proper installation. However, torque beyond specified values will not improve sealing.Exceeding the specified torque by more than 25% may cause damage to the product, resulting in pipe-joint failure.
Using Impact WrenchesWhen using an impact wrench, the speed of assembly may require extra care to ensure nuts are tightened evenly by alternating sides until proper assembly is complete.Impact wrenches do not provide the installer with direct “wrench feel” or torque to judge nut tightness. Since some impact wrenches are capable of high output, it is important to develop a familiarity with the impact wrench to avoid damaging or fracturing bolts or coupling bolt pads during installation.DO NOT continue to use an impact wrench after the visual installation guidelines for the coupling are achieved.Perform trial assemblies with the impact wrench and socket or torque wrenches to help determine the capability of the impact wrench. Using the same method, periodically check additional nuts throughout the system installation.In addition, verify that proper impact grade sockets are being used for couplinginstallation.

Note: Allowable Axial Displacement figures are for roll grooved standard steel pipe. Values for cut grooved pipe will be double that of roll grooved. These values are maximums; for design and installation purposes these figures should be reduced by: 50% for ¾” – 3½”; 25% for 4” and larger to com-pensate for jobsite conditions.• Working Pressure and End Load are total, from all internal and external loads, based on standard weight (ANSI) steel pipe, standard roll or cut grooved in accordance with ARGCO specifications. • When assembling ARGCO couplings onto end caps, take additional care to make certain the end cap is fully seated against the gasket end stop.
ARGCO Grooved Couplings are suitable for fire protection systems, water supplysystems, and other process systems of higher working pressure.
The NFPA 13 defines a flexible coupling as;
"a listed coupling or fitting that allows axial displacement, rotation, and at least 1 degree of angular movement of the pipe without inducing harm on the pipe. For pipe diameters of 8 in. and larger, the angular movement shall be permitted to be less than 1 degree but not less than 0.5 degrees.” (NFPA 13- 2007 3.5.4)
For sprinkler systems, NFPA 13 specifies the use of flexible couplings to protect the system against damage from earthquakes and sets some specific examples of how and where they should be used. Designers and installers should design their fire protection sys-tems in compliance with this standard.

The ARGCO Model 105 reducing coupling allows for direct reduction on a piping run and eliminates the need for a concentric reducer and couplings.The specially designed rubber gasket helpsprevent small pipe from telescoping into larger pipe during vertical assembly.
Caution: Model 105 couplings should not be used with an end cap, as the end may be sucked into the pipe when draining the system.
