Butt-Weld Elbow — Precision for Fluid Direction Change

Butt-weld elbow is a pipe fitting designed to alter the direction of fluid flow in pipeline systems. Connected via butt welding, these elbows provide precise angle changes (45°, 90°, or 180°) for efficient fluid distribution. They are commonly used in oil, gas, chemical, and industrial pipeline networks.
