In July 1993, the ASME B16 Committee gave to its Subcommittee C the assignment to convertthe API 590 Steel Line Blanks Standard into an ASME standard. The American Petroleum Instituteno longer publishes the API 590 Standard.
These line blanks were designed in accordance with the rules of the ASME B31.3-2002 edition.Materials and relevant footnotes have been added following the ASME format.
Significant additions were made to the 2005 edition that included reference to the use of allmaterials listed in B16.5 Table 1-A plus Metric units. The added materials of construction includedadditions to classes of alloy steels, stainless steels, and nickel alloys. The 2005 edition was alsometricated over previous editions to include both U.S. Customary units (in parenthesis) andMetric units in the text, Metric units in dimensional tables in the body, and U.S. Customary unitsin dimensional tables in Nonmandatory Appendix A.
Following the approval of the Standards Committee and ASME, approval for the 2005 editionwas granted by the American National Standards Institute on September 19, 2005.
The 2010 edition includes revisions to paragraph numbering and adjustments of appendices.In addition to renumbering of main text, updates have been made to the Materials section andMarking Method. Illustrations for the figure-8 blanks for raised face flange joints have beenrevised. Finally, the tables for male ring-joint facing figure-8 blanks were revised to support bothoval and octagonal ring shapes.
All requests for interpretations or suggestions for revisions should be sent to the Secretary,B16 Committee, The American Society of Mechanical Engineers, Three Park Avenue, New York,NY 10016-5990.
The B16 Committee operates under procedures accredited by the American National StandardsInstitute (ANSI). Following approval by the Standards Committee and ASME, this revision tothe 2005 edition was approved as an American National Standard by ANSI on September 2, 2010with the designation ASME B16.48-2010.

LINE BLANKS
1 SCOPE
This Standard covers pressure–temperature ratings,materials, dimensions, tolerances, marking, and testingfor operating line blanks in sizes NPS 1⁄2 through NPS 24for installation between ASME B16.5 flanges in the 150,300, 600, 900, 1500, and 2500 pressure classes.
2 GENERAL
2.1 Definitions
2.1.1 Figure-8 Blank. A figure-8 blank (also calleda spectacle blank) is a pressure-retaining plate with onesolid end and one open end connected with a web ortie bar (see Fig. 1).
2.1.2 Paddle Blank. A paddle blank is similar tothe solid end of a figure-8 blank. It has a plain radialhandle. It is generally used in conjunction with a paddlespacer in large sizes.
2.1.3 Paddle Spacer. A paddle spacer is similar tothe open end of a figure-8 blank. It has a plain radialhandle. It is generally used in conjunction with a paddleblank.
2.2 References
Codes, standards, and specifications, containing pro-visions to the extent referenced herein, constituterequirements of this Standard. These reference docu-ments are listed in Mandatory Appendix II.
2.3 Quality Systems
Nonmandatory requirements relating to the productmanufacturer’s Quality System Program are describedin Nonmandatory Appendix A.
2.4 Relevant Units
This Standard states values in both Metric andU.S. Customary units. These systems of units are to beregarded separately as standard. Within the text, theU.S. Customary units are shown in parenthesis or sepa-rate tables. Refer to Mandatory Appendix I. The valuesstated in each system are not exact equivalents; therefore,it is required that each system of units be used indepen-dently of the other. Combining values from the twosystems constitutes nonconformance with the Standard.Mandatory Appendix I provides dimensions inU.S. Customary units.
1
2.5 Convention
For the purpose of determining conformance withthis Standard, the convention for fixing significant digitswhere limits and maximum and minimum values arespecified, shall be rounded as defined inASTM Practice E 29. This requires that an observed orcalculated value shall be rounded off to the nearest unitin the last right-hand digit used for expressing the limit.Decimal values and tolerances do not imply a particularmethod of measurement.
2.6 Size
NPS, followed by a dimensionless number, is the des-ignation for nominal blank size. NPS is related to thereference nominal diameter, DN, as defined in ISO 6708.The relationship is typically as follows:
NPS DN
1⁄2 153⁄4 201 25
11⁄4 3211⁄2 402 50
21⁄2 653 804 100
NOTE: For NPS ≥ 4, the related DN p 25(NPS).
2.7 Service Conditions
Criteria for selection of materials suitable for particu-lar fluid service are not within the scope of this Standard.
3 PRESSURE–TEMPERATURE RATINGS
3.1 Pressure Classes
Line blanks covered by this Standard are for the fol-lowing pressure classes: 150, 300, 600, 900, 1500, and2500 as listed in ASME B16.5.
3.2 Pressure–Temperature Ratings
3.2.1 Ratings. Ratings are the maximum allowableworking gage pressure at the temperature shown inTables 2 and II-2 of ASME B16.5 for the appropriatematerial and pressure class. For intermediate tempera-tures, linear interpolation between temperatures withina pressure class is permitted by ASME B16.5.
3.2.2 System Pressure Testing. Line blanks may besubjected to system tests at a pressure not to exceed

1.5 times the 38°C (100°F) rating rounded off to the nexthigher 1 bar (25 psi) increment. Testing at any higherpressure is the responsibility of the user, taking intoaccount the requirements of the applicable code orregulation.
3.2.3 Mixed Material Joints. Should either the twoflanges or the line blank in a flanged line blank assemblynot have the same pressure-temperature rating, the rat-ing of the assembled joint at any temperature shall bethe lower of the flange or line blank rating at thattemperature.
4 DESIGN
4.1 Handle
The handle or web (tie bar) may be integral or attachedto the line blank or spacer. The web and its attachmentshall be capable of supporting the weight of the blankor spacer in all orientations without permanent defor-mation to the web.
