An ASTM A335 P22 tee is a fitting with a 90° branch that splits or combines flow, for use with ASTM A335 P22 pipe. ASTM A335 P22 itself is a pipe or plate specification, so the matching tee is made to ASTM A234 WP22 (buttweld) · ASTM A182 F22 (forged) — which is what we supply for P22 lines. Equal tees have the same size branch as the run; reducing tees have a smaller branch. Barred tees add internal bars so pipeline pigs pass the branch.

ASTM A335 P22 Tee — questions buyers ask
What is a barred tee?
A tee with bars welded across the branch opening so a pipeline pig cannot enter the branch.
Which standard covers ASTM A335 P22 tees?
The material is ASTM A234 WP22 (buttweld) · ASTM A182 F22 (forged); dimensions follow ASME B16.9 · B16.11. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a ASTM A335 P22 tee?
The steel price, the size and schedule or class, quantity, and the testing and documents required. Send your list and we quote the same working day.
What documents do you supply?
EN 10204 3.1 mill certificates as standard, 3.2 with third-party inspection on request, plus dimensional and PMI reports.
