Overview Of 45 Degree Butt Weld Elbow
45 degree butt weld elbow (BW elbow) is a core butt-weld pipe fitting applied to turn pipeline route with a gentle 45° angle. It adopts seamless hot forming technology, uniform wall thickness, smooth inner surface to reduce fluid resistance.
For full pipeline layout design, you may also check our 180 Degree Butt Weld Bend to achieve U-turn routing, and the Seamless Concentric Butt-Weld Reducer for pipe diameter transition in your piping system.
We produce long radius 45° elbows as standard, short radius type available for custom orders. Raw material carbon steel A234 WPB / MS mild steel, fully comply with ASME B16.9, ASTM, IS 1239 industry standards. All goods keep full nominal size with zero minus tolerance, no thin-wall cutting corners.
