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 Of Threaded Equal Tee

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.

Our ASME B16.11 threaded equal tee is commonly used together with Threaded Hex Head Pipe Plug and Threaded Forged Union to build complete high-pressure small-bore instrument piping systems. All these forged threaded fittings adopt hot forging technology, comply with ASME B16.11 and MSS SP-79 standards, and are available in carbon steel A105 and stainless steel F304/F316L for hydraulic, fire fighting and chemical pipeline projects.

Our threaded equal tee is manufactured in accordance with ASME B16.11, the standard covering forged socket-weld and threaded pipe fittings for high pressure small bore piping.

FAQ

Q1: What is the difference between equal tee and reducing threaded tee?

A: Equal threaded tee has three ports of identical diameter; reducing threaded tee comes with a smaller‑size branch port for different‑diameter pipeline split.

Q2: Do your threaded tees have minus‑tolerance on wall‑thickness?

A: All our forged pipe fittings are strictly manufactured to full‑nominal standard dimensions. We guarantee zero minus‑tolerance on wall‑thickness and thread sizes without thin‑wall cutting‑corners.
