| a. Standards of Flanges |
ASTM/ASME/ANSI Standards
B16.47 Factory-Made Wrought Steel Butt-Welding Fittings
B16.5 Wrought Steel Butt-Welding Short Radius Elbows and Returns
MSS Standards
MSS flange standards were adopted by American National Standards Institute. MSS flange standards start with an SP followed by a number. MSS SP-9 is the standard for spot facing flanges. MSS SP-44 is the standard for steel pipeline flanges. MSS SP-60 is the standard for connecting flange joint.
SP-44
API Standards
API flanges are designed to handle very high pressures and temperatures. API flanges have a smaller bolt circle than MSS flanges. All API flanges are ring joint flanges. API flange standards start with a number followed by a letter. API standard 17D is the specification for sub-sea well head flanges.
