45 Degree Socket Weld Elbow | ASME B16.11 Forged SW Elbow

Overview Of 45 Degree Socket Weld Elbow

45° Socket Weld Elbow is a forged fitting with socket weld ends, used to change pipeline direction by 45 degrees in small diameter high-pressure piping systems.

This series is forged from stainless steel A182 F304 / F316L, featuring integrated forming, uniform wall thickness and anti-corrosion performance. All products follow full standard dimensions with zero minus tolerance, no thin-wall cutting corners. Multiple pressure classes (3000LB / 6000LB / 9000LB) are available to match different pressure working conditions.For other forged socket‑weld fittings, please check our 90 Degree Socket Weld Elbow and Socket Weld Lateral Tee product pages.

FAQ

Q1: What material are your 45° socket weld elbows?

A: Standard materials are stainless steel A182 F304 and A182 F316L. Carbon steel A105 forged SW elbows are also available on request.

Q2: Do these socket weld elbows have minus tolerance on wall thickness?

A: All our forged pipe fittings are strictly produced to full standard nominal dimensions. We guarantee zero minus tolerance on OD and wall thickness, never use thinner raw materials to cut cost.

Q3: What pressure ratings can this 45° SW elbow support?

A: We supply three standard pressure classes: 3000LB, 6000LB, 9000LB as per ASME B16.11 high-pressure standard.

Q4: What documents can you provide for customs clearance?

A: We provide full export documents including Material Test Certificate (MTC), MPI NDT test report, dimensional inspection report, commercial invoice and packing list.
