1 in (25 mm) Buttweld 90 Degree SR Elbow, Std | WE25SR
Available
This AAP buttweld 90 degree short radius elbow is made from carbon steel to ASTM A234 WPB, ANSI B16.28 (manufacturer-stated). It is supplied in 13 sizes, 1 in (25 mm) to 12 in (300 mm).
A short radius elbow turns the pipe run through 90 degrees in less space than a long radius elbow: its centre to end distance is shorter than the long radius elbow of the same size. It is welded end to end with the pipe.
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
- Changing the direction of a welded pipe run through 90 degrees where space is tight
- Compact bends in welded pipework

Selecting the right option
Match the wall thickness to the pipe you are welding to. AAP does not publish a pressure rating for the fittings themselves.
