ASME B16.5 2 Inch Socket Weld Flanges Stainless Steel Flanges

ASME B 16.5 2 inch socket weld (SW) flanges are used for small size and high pressure pipe systems.Stainless steel flanges are more expensive than carbon steel flanges because of the better functions.The pressures could be chosen:CL150,CL300,CL600,CL900,CL1500,CL2500.

Rated 5/5 based on 343 customer reviews

ASME B16.5 2 inch socket weld flanges are small size flanges that play an important role in piping systems.Stainless steel flanges always used in chemcial applications because of the excellent anti-corrosive function.ASME B16.5 forged flanges have sizes 1/2″-48″,for flanges of large size ( more than 26 inch ),there is ASME B16.47 A&B  Standard.


Types of Flanges

ASME B16.5 is a American Standard of forged flanges,including Weld Neck (WN) flanges,Slip On (SO) flanges,Socket Weld (SW) flanges,Threaded (THD) flanges,Blind Flanges (BL),Lap Joint flanges (LAPJ).
