Alloy Steel Pipe Fittings
Seamless & welded alloy steel butt-weld fittings — elbows, tees, reducers and return bends in chrome-moly WP grades for high-temperature power and refinery piping.
Product Overview
Our alloy steel fittings range completes the piping circuit — directional and branch connections, diameter transitions and terminations — manufactured to the same chrome-molybdenum grade families as our alloy steel pipe stock so material properties stay consistent across a project.
Fittings are available seamless or welded, in the full dimensional range from ASME B16.9, and are dispatched with matching mill certification and heat treatment records to your pipe order.
