The Manufacturers Standardization Society (MSS) of the Valve and Fittings Industry is excited to announce publication of the new Standard Practice SP-158-2021, Supplemental High-Pressure Gas Test Procedures for Valves.
Standard Practice (SP)-158 provides a testing protocol to be applied to valves requiring supplementary high-pressure gas testing because of hazardous, unique, or severe service requirements. This Standard Practice details supplemental procedures for high-pressure gas testing of valves, which may be utilized for any category of service where supplementary pressure boundary and closure integrity are desired. SP-158 was developed under MSS Technical Committee 114, Steel Valves, and will be transferred and maintained under the consensus of MSS Technical Committee 410, Severe and Special Service Valves.
The new Standard Practice, MSS SP-158-2021, is now available from authorized U.S. and global distributors. It has been published in an electronic version (PDF) and in book format.
Also, SP-92-2021, Valve User Guide, has been revised and published by MSS.
Standard Practice (SP)-92 has served the industry for over 41 years; providing a standardized informational guide to assist industrial valve users engaged in a variety of applications and in various operating environments. The information is divided into five main sections: “References”, “Selection”, “Shipping and Storage”, “Installation”, and “Operation and Maintenance”. SP-92 continues to be maintained under the consensus of MSS Technical Committee 306, Valve Operation.
The revised Standard Practice, MSS SP-92-2021, is now available from authorized U.S. and global distributors. It has been published in an electronic version (PDF) and in book format.
