1 x 1/2 in (25 x 15 mm) Buttweld Concentric Reducer, X-Stg | WCR2515X
Available
This AAP buttweld concentric reducer is made from carbon steel to ASTM A234 WPB, ANSI B16.9 (manufacturer-stated). It is supplied in 22 sizes, 1 x 1/2 in (25 x 15 mm) to 6 x 5 in (150 x 125 mm).
A concentric reducer steps a pipe run from one size down to a smaller size, with both ends on the same centreline. This is the X-Stg (extra strong) weight, with a thicker wall than the Std weight of the same size. Sizes are listed as the larger size first, then the smaller.
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
- Reducing a welded pipe run from a larger size to a smaller one
- Heavier wall pipework that needs X-Stg fittings
Features
- 22 sizes, 1 x 1/2 in (25 x 15 mm) to 6 x 5 in (150 x 125 mm)
- Butt weld ends, ASTM A234 WPB, ANSI B16.9 (manufacturer-stated)
- Wall thickness listed for every size

Dimensions are in millimetres, as lettered on the AAP drawing: A1 and A2 are the outside and inside diameters of the larger end, B1 is the outside diameter of the smaller end, and C is the overall length. AAP also lists the inside diameter of the smaller end, but it does not agree with the wall thickness AAP lists, so it is not shown.
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.
