45 Degree Socket Weld Lateral Tee

Overview Of 45 Degree Socket Weld Lateral Tee

45° Socket Weld Lateral Tee, also known as Y‑Tee, is a forged socket‑weld pipe fitting. It creates a 45‑angled branch from main pipeline. Socket‑weld connection delivers outstanding sealing strength, ideal for high‑pressure small‑bore piping systems.

All our lateral tees are hot forged from A105 carbon steel, strict dimensional inspection to full nominal size without minus tolerance. We follow ASME B16.11 industry standard, supporting custom pressure classes (3000# / 6000# / 9000#) and all standard inch sizes.

Core Advantages Of 45 Degree Socket Weld Lateral Tee

Hot forged integrated forming, high pressure & impact resistance

FAQ

Q1: What is the difference between lateral tee and standard straight tee?

A: Straight tee divides flow at 90°, while 45° lateral Y tee branches pipeline at a gentle 45° angle, lowering fluid resistance for smoother medium transportation.

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

A: All our forged pipe fittings are strictly manufactured to full standard nominal dimensions, zero minus tolerance on outer diameter and wall thickness, we never cut corners with thin walls.
