Valve with flange
Thread Content
Dear teachers, for 150LB flanges used with American standard valves, what execution standard should be adopted?
Valve Standard MSS of the American Society of Valve and Fitting Manufacturers
ASME B16.5 – for sizes over 26\", use 16.47
Generally, it is in accordance with ASME B16.47. But for US standards, I think the standards are all the same
The best is ASME B16.5; followed by SH/T3406-2013 or HG/T20615-2009, and even GB/T9112 also has options
Glass fiber reinforced plastic flanges are also available, in accordance with manufacturer standards. ;P
ASME B16.5 B16.47
The American standards should all be the same
ASME B16.5-2013 Pipe Flanges and Flanged Fittings (NPS1...2 to NPS24)
