Tees branch a line or join two flows. On an equal tee the run and branch are the same size; on a reducing tee the branch is smaller.
We make tees to GB, SHJ, HGJ, ANSI, JIS, DIN and other standards, or to your drawing. Tees are in the approved scope of our China Petrochemical Materials and Equipment Network qualification certificate, valid until 10 July 2028.

Questions
What tee sizes can you make?
Send the run and branch nominal sizes, wall schedule and material, and we will confirm each item against our production capacity.
Can tees ship together with elbows and reducers?
Yes. We make elbows, tees, reducers, caps and flanges, so all fittings for one project can be quoted together.
