Butt Weld Tee Grade Selector by Service

Match an ASME B16.9 tee to your service before you spec it — the grade error that surfaces two years later.

Logic per ASTM A234 (carbon/alloy), A420 WPL6 (low-temp), ASTM A403 (stainless), NACE MR0175/ISO 15156 (sour), EN 10204 (MTC). Always confirm MAWP against wall, OD and design temperature.
