MSS publishes revised American National Standard for Steel Pipeline Flanges

Nov. 30, 2016
The first edition of MSS SP-44 was published in 1952 MSS SP-44 was originally developed under the consensus of the MSS Technical Committee 110 (Steel Flanges & Flanged Fittings) SP-44 is already Incorporated By Reference into the U.S. Code of Federal Regulations and contains construction details not covered by other standards

VIENNA, VA – The Manufacturers Standardization Society (MSS) announces that the substantially revised Standard Practice, SP-44-2016, Steel Pipeline Flanges, has been approved by the American National Standards Institute (ANSI) as a Revised American National Standard (ANS).

The first edition of MSS SP-44 was published in 1952. Today, it is widely employed in the valve and piping industries and referenced in other industry and ANSI-approved standards. SP-44 was originally approved as an ANS in 2014 and continues to give the industry a “National Standard” for NPS 12 to NPS 60 flanges for high-yield strength materials that are not covered by other current national standards.

MSS SP-44 was originally developed under the consensus of the MSS Technical Committee 110 (Steel Flanges & Flanged Fittings) and is today utilized in many industrial sectors; including Paper, Chemical, Petroleum Production and Transport, Petrochemical, Nuclear Power, Hydroelectric Power, and those enterprises involved with Fossil Fuel Power flanged piping joints, including valve and fitting systems. This Standard Practice addresses pressuretemperature ratings, materials, dimensions, tolerances, marking, and testing. SP-44 is already Incorporated By Reference into the U.S. Code of Federal Regulations and contains construction details not covered by other standards; including P/T ratings of products made of high-yield strength materials (e.g., for users that have flanged joints, flanged valves, and flanged fittings).

The newly revised and ANSI-approved American National Standard version, ANSI/MSS SP-44-2016, along with all MSS Standard Practices, are available from MSS and through authorized distributers world-wide.
