Their use expanded steadily as temperatures andpressures were increased in steam plants. Tests examining their application in flanges and valveswere conducted as early as 192

This standard wasknown as API Specification 6B, Ring-Joint Flanges. Following the acceptance of ring-joints forflanges and valves
24、by API and the issuance of their standard, ASA B16e on Steel Pipe Flangesand Flanged Fittings was revised to include them, and the 1939 edition included standarddimensions for a full line of ring-joint flanges based on the API standard.
