The tee is a pipe fitting and a pipe connector. The tee is usually used at the branch pipe of the main pipeline. The tee is divided into equal diameter and different diameter, and the ends of the equal diameter tee are all the same size; The size of the main pipe is the same, while the size of the branch pipe is smaller than that of the main pipe. For the use of seamless pipes to manufacture tee, there are currently two commonly used processes: hydraulic bulging and hot pressing. Divided into electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.

Frequently Asked Questions (FAQ)
What is a pipe tee and what is its primary function?
A pipe tee is a T-shaped pipe fitting featuring two outlets at 90° to the connection to the main line. It is primarily used to connect pipelines to branch off fluid or gas flow in distribution systems.
What is the difference between an equal tee and a reducing tee?
An equal diameter tee has all three ends of the same diameter size. A reducing tee (different diameter tee) has a branch outlet that is smaller in diameter than the run/main pipe outlets.
What manufacturing processes are used for seamless pipe tees?
The two most common manufacturing processes for seamless pipe tees are hydraulic bulging and hot pressing. Additional processing methods include bending, extrusion, pushing, molding, and precision machining.
What materials are available for pipe tee production?
Pipe tees are manufactured from various materials including Carbon Steel (ASTM/ASME A234 WPB-WPC), Alloy Steel, Stainless Steel (304, 316, 321, 347 series), Low Temperature Steel, and High-Performance Steel depending on operational demands.
What size ranges do you offer for seamless and seamed tees?
We supply seamless tees ranging from 1/2" to 24" (DN15–DN600) and seamed (welded) tees from 4" to 78" (DN150–DN1900), with wall thicknesses available up to 150mm.
Which international manufacturing standards do your pipe fittings comply with?
Our industrial pipe fittings conform to major international standards including ASME B16.9, JIS (B2311/B2312/B2313), GB, ISO, API, EN, DIN, BS, SH, and SY standards.
