Alloy C-22 · UNS N06022
A Hastelloy C22 tee is a fitting with a 90° branch that splits or combines flow, made from Hastelloy C22 to ASTM B366 WPHC22 (buttweld) · ASTM B564 (forged). 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.
