ASME carbon steel butt-weld fittings selection guide

Product function

Wrought carbon steel butt-weld fittings (elbows, tees, reducers and caps) manufactured to ASME B16.9, with beveled ends for welding to carbon steel pipe.

Selection criteria

Materials: ASTM A234 WPB and WPC (ambient and higher temperature), ASTM A420 WPL3, WPL6 and WPL9 (low temperature).

Sizes NPS 1/2" to 60"; wall thickness STD, XS, XXS and Sch.20 to 160. Short radius elbows follow ASME B16.28 and welding ends ASME B16.25.

Dimensions are in inches. Outside diameters can differ from KS fittings, so confirm the piping standard first.

Information for quotation

Provide the shape (long/short radius elbow, tee, concentric/eccentric reducer, cap), nominal size, wall thickness (schedule), material and quantity.

Specify the dimensional standard (KS/JIS or ASME). The same nominal size can have different outside diameters and dimensions under each standard.

State any material documentation (for example mill test reports) required at the time of the quotation request.
