The Manufacturers Standardization Society (MSS) of the Valve and Fittings Industry announces that SP-65-2019, high-pressure chemical industry flanges and threaded stubs for use with lens gaskets, has been revised and published by MSS.
Standard Practice (SP)-65 has served as an industry norm for over 57 years; covering requirements for cast and forged steel flanges (welding neck and straight threaded) and threaded stubs, designed especially for use in the chemical industry, with end connections making use of lens gaskets. This Standard Practice is similar in intent to ASME B16.5; however, it governs a higher pressure class and a lens gasket connection. SP-65 continues to be maintained under the consensus of MSS Technical Committee 110, Steel Flanges & Flanged Fittings.
The revised Standard Practice, MSS SP-65-2019, is now available from authorized U.S. and global distributors. It has been published in an electronic version and in book format.
