2 in (50 mm) Buttweld Cap, X-Stg | WC50X
Available
This AAP buttweld cap is made from carbon steel to ASTM A234 WPB, ANSI B16.9 (manufacturer-stated). It is supplied in 6 sizes, 2 in (50 mm) to 10 in (250 mm).
A cap closes the end of a welded pipe run. It is welded to the pipe end. This is the X-Stg (extra strong) weight, with a thicker wall than the Std weight of the same size. C is its overall length.
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.

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.
