The ASTM A234 WP11 SCH160 Equal Tee is a high-pressure, low-alloy "Chrome-Moly" fitting designed for severe service. Containing 1.25% Chromium and 0.5% Molybdenum, it offers superior creep strength and heat resistance. The SCH160 wall thickness provides the heavy-duty reinforcement needed for extreme pressure loads. This Equal Tee ensures a seamless 90° branch with a uniform diameter, utilized primarily in high-pressure steam headers and refinery catalytic units.
