Alloy steel pipe elbows are curved butt-weld fittings made from chrome-molybdenum alloys like ASTM A234 WP11, WP22, or WP91, used for 90°/45° direction changes in high-temperature/pressure piping systems such as power plants and refineries. They offer superior creep resistance up to 1200°F compared to carbon/mild steel variants, with long/short radius options matching prior 3D bends, U-bends, caps, unions, reducers, and flanges.  ​

Types

• Long Radius (LR): 1.5D radius minimizes erosion (e.g., 6" NPS: 229mm center-to-end).

• Short Radius (SR): 1D for compact spaces.  ​
