SOFF ANSI / AWWA C207 / C228 CLASS D Flange ASME ASTM BS DIN 14" 170-150PSI

ASTM, BS, and DIN are standards organizations that provide specifications for various products, including flanges. The term "14" 170-150PSI flange" refers to a specific type of flange that meets the requirements of these standards.

ASTM refers to the American Society for Testing and Materials, which sets standards for various materials, including flanges. BS refers to the British Standards, which provides specifications for various products, including flanges. DIN refers to Deutsches Institut für Normung, the German Institute for Standardization, which sets standards for various products, including flanges.

The "14" in the term refers to the nominal pipe size (NPS) of the flange, which indicates the approximate inside diameter of the flange. In this case, it refers to a flange designed to fit a pipe with a 14-inch diameter.

The numbers 170-150 PSI refer to the pressure rating of the flange. It indicates the maximum pressure the flange can withstand without leaking or failing. In this case, the flange is rated for a pressure range of 170 to 150 pounds per square inch (PSI).

Overall, the term "ASTM BS DIN 14" 170-150PSI flange" specifies a flange that meets the standards set by ASTM, BS, and DIN, with a nominal pipe size of 14 inches and a pressure rating of 170-150 PSI.
