90 DEG Socket Weld Elbows ASME B16.11 Stainless Steel Pipe Fittings

90 deg socket weld elbows are belong to ASME B16.11 stainless steel pipe fittings.SW elbows have two types:90 DEG and 45 DEG.SW pipe fittings including:Elbow, Tee, Cross, Coupling, Union, Cap, Reducing Insert, Sockolet.Three pressures for customers to choose:3000LB,6000LB,9000LB.

Rated 4.8/5 based on 525 customer reviews

90 deg socket weld (SW) elbows are used in piping systems to change the direction of the pipes in 90 degree angle.ASME B16.11 stainless steel pipe fittings are stainless forged pipe fittings in American Standard.As pipe systems usually transfer fluids or gas,socket weld fittings are always be chosen because of the excellent anti-leakage function.


Socket weld pipe fittings mainly used for small pipe diameters because the dimension range is very small 1/8″-4″.


SW elbows ae belong to high pressure forged fittings,so the pressures can be chosen are CL3000,CL6000,CL9000;to meet different demands.



  • The connected pipes do not need to be beveled for welding.
  • Small risk of leakage.
