Many standards play an important role in the design and production of forged steel valves, fit tings, flanges and unions. These standards cover material, product dimension and design, procedure, and safety.

Material standards are sponsored by such organizations as the American Society for Testing and Materials (ASTM), the American Iron & Steel Institute (AISI), and the Society of Automotive Engineers (SAE).

The American National Standards Institute, Inc., whose membership is composed of both user and producer groups, serves as the issuing agency for the majority of product standards related to the valve and fittings industry. Product standards are also issued by Individual user and producer agencies such as the American Petroleum Institute (API) and the Manufacturers’ Standardization Society of the Valve & Fittings Industry (MSS). The latter is an active member of ANSI.

Procedural and safety standards are issued by ANSI. MSS and the American Society of Mechanical Engineers (ASME).

Following is a partial list of agencies whose standards have a direct bearing on the design and production of forged steel valves, fittings, flanges and unions. Some of the more significant standards are listed under the issuing agency.
