If you work in the piping industry, chances are you’ve heard of MSS standards. But what do they mean? In this blog post, we’ll explore what MSS stands for and list out some of the most important MSS standards that every professional in the piping industry should know.
What Does MSS Stand For?
MSS stands for Manufacturers Standardization Society, which is an American-based trade organization founded in 1933 to promote standardization among manufacturers. It was originally known as the Valves and Fittings Committee but changed its name to the Manufacturers Standardization Society (MSS) in 1957. The organization has over 6,000 members worldwide and is responsible for creating numerous standards for piping products, components, and systems.
List of Important MSS Standards
The following is a list of some of the most important MSS standards that apply to the piping industry:
- MSS SP-6 – Standard Finishes for Contact Faces of Pipe Flanges and Connecting-End Flanges of Valves and Fittings
- MSS SP-25 – Standard Marking System for Valves, Fittings, Flanges & Unions
- MSS SP-43 – Wrought Stainless Steel Butt-Welding Fittings
- MSS SP-58 – Quality Standard for Steel Castings & Forgings Used in Piping Applications
- MSS SP-97 – Integrally Reinforced Forged Branch Outlet Fittings – Socket Welding & Threaded Types
- MSS SP-114 – Quality Standards for Steel Castings & Forgings Used in Piping Applications with Supplementary Requirement S1
- MSP SP-134 – Qualification Procedure for Carbon & Low Alloy Steel Butt Welder Operators
These are just a few examples; there are many more specific standards depending on your application. It’s important to become familiar with these standards so you can ensure your products meet them when designing or manufacturing components or systems within the piping industry.
