Overview
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.
Core Features
- Hot one-piece forging structure, high mechanical strength and pressure resistance
- Socket weld connection, easy welding, tight sealing for high-pressure service
- Material: Stainless Steel A182 F304, A182 F316L, excellent rust & acid resistance
- Standard compliance: ASME B16.11, MSS SP-79
- Complete size range: 1/8″ ~ 4″
- Zero minus tolerance on outer diameter and wall thickness
- Surface: Natural forged finish, smooth inner bore to reduce fluid resistance
- Full non-destructive testing & hydrostatic test before delivery, complete MTC certificates provided

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.
Q5: Can I order custom sizes?
A: Yes, we accept custom drawing processing for special sizes, wall thickness and angles based on customer requirements.
