Tee vs Weldolet vs Stub-in Branch Fitting Selector | Synbase Steel

Branch Connection Selector: Tee vs Olet vs Stub-in

There is no single code rule — the choice is total installed cost and stress, not sticker price. This routes on branch ratio and service.

Logic from ASME B31.3 (both reducing tees and integrally-reinforced branch fittings permitted) + piping-engineering practice. Final selection is subject to your stress analysis.
