Socket Weld Equal Tee | Forged Carbon Steel SW Tee

Our socket weld equal tee is one-piece hot forged pipe fitting with three identical socket weld ends, used for equal-diameter pipeline branching. Manufactured strictly to ASME B16.11, all sizes keep full nominal dimension without minus tolerance, widely used for high-pressure instrument, hydraulic and fire control piping.

Overview

Socket Weld Equal Tee is a forged three-way fitting with same nominal diameter on all three ports, adopting socket weld connection method to split or converge pipeline medium flow.

This fitting is integrally hot forged from carbon steel A105 (stainless steel A182 F304/F316L optional), with thick uniform wall and high compressive resistance. We strictly control all dimensional parameters, guarantee zero minus tolerance on outer diameter and wall thickness, no thin-wall material cutting corners. Available in 3 pressure classes: 3000LB, 6000LB, 9000LB to meet various high-pressure working conditions.

FAQ

Q1: What’s the difference between equal tee and reducing tee?

A: Socket weld equal tee has three ports of the same diameter for equal pipeline branching; reducing tee has one smaller branch port for different-diameter pipeline split.

Q2: Do your socket weld tees have minus tolerance on wall thickness?

A: All our forged pipe fittings are produced strictly per full nominal standard dimensions. We promise zero minus tolerance on outer diameter and wall thickness, no thin material to reduce cost.
