1/2 in (15 mm) Buttweld 90 Degree LR Elbow, Std | WE15
Available
This AAP buttweld 90 degree long radius elbow is made from carbon steel to ASTM A234 WPB, ANSI B16.9 (manufacturer-stated). It is supplied in 20 sizes, 1/2 in (15 mm) to 24 in (600 mm).
A long radius elbow turns the pipe run through 90 degrees with a gradual bend. It is welded end to end with the pipe, so the joint is a continuous weld instead of a thread or flange.
AAP describes its buttweld range as carbon alloy steel to ASTM A234 for use in various piping systems. AAP lists these advantages of buttweld (manufacturer-stated): a welded fitting is permanently leak proof, the continuous metal between pipe and fitting adds strength, the smoother inner surface and gradual direction changes reduce pressure loss, turbulence, corrosion and abrasion, and a welded system uses a minimum of space.
Where this product is used
- Pipework where a welded, permanently leak proof joint is wanted, as AAP describes for buttweld
