Threaded Equal Tee
Our forged threaded equal tee is a one‑piece hot‑forged three‑way fitting with internal NPT taper thread on all three ends. It is used to split or combine flow inside threaded pipelines. Produced strictly following ASME B16.11 and MSS SP‑79 standards, all sizes maintain full nominal dimension without minus tolerance, widely used for power‑plant instrument, hydraulic, fire‑fighting and chemical high‑pressure small‑bore piping systems.
Overview
Threaded Equal Tee is hot‑forged three‑way pipe fitting with identical‑size female NPT threads on three ports. It serves for pipeline diversion and confluence of same‑diameter threaded piping.
We adopt hot‑forging forming followed by CNC precision thread‑machining process. Available materials include carbon‑steel A105 and stainless‑steel A182‑F304 / F316L. Internal threads are precisely machined according to American NPT standard for leak‑proof performance under high‑pressure conditions. We strictly control wall‑thickness and thread dimension, guarantee zero minus‑tolerance without thin‑wall cutting‑corners. Three pressure classes: Class3000, Class6000, Class9000 are available for different working‑pressure requirements. We can also produce reducing threaded tee for unequal‑diameter branch upon request.
