Branch off or combine a flow

An equal tee creates a 90° branch the same size as the main line. It feeds a new branch, combines two inlets, or takes an instrument, a drain or a bypass valve.

Compared with a branch welded straight onto the pipe, a butt-weld tee keeps a controlled wall thickness around the outlet and only needs butt welds, which are easier to inspect. Our tees come in A234 WPB to ASME B16.9 (STD or XS, painted) and in S235 to EN 10253-1 (black or galvanized), Ø 60.3 to 219.1 mm.

If the branch is smaller than the line, combine the tee with a concentric reducer on the outlet.

Frequently asked questions

Do you make reducing tees?

Our standard references are equal tees. For a smaller branch, use an equal tee with a reducer. Reducing tees can be made to drawing: send us your specification.

Can an equal tee combine two flows?

Yes, it works both ways. For two merging flows, bring both in from the opposite run ends and take the combined flow out of the branch.

What documents come with the delivery?

An EN 10204 3.1 inspection certificate, with the heat number marked on each fitting.
