Stainless Steel Butt Weld Elbow Long Radius
Stainless Steel Butt Weld Elbow Long Radius
Specifications
The Butt Weld Elbow is a pipe fitting used to change the direction of flow in a piping system. Manufactured in accordance with ASME B16.9 dimensional standards, these elbows are butt-welded directly to pipe, creating a permanent, full-strength joint that can be radiographically inspected.
