Buttweld Pipe Fitting Specification & Standards

Welded Pipe fittings are made as per ASME spec B16.9. Asme B16.9 covers factory made wrought steel butwelding fittings in sizes 1/2" to 48". This standard however does not cover low pressure corrosion resistant buttwelding fittings. See MSS SP-43, Wrought Stainless Steel Butt-Welding Fittings.

Common Materials for Welded Pipe Fittings

Carbon Steel Welded Fitting:

A234 WPB is the most common material used for carbon steel butt welded fittings.

Astm A234 WPB is the Standard Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperature Service.

Specifications   

ASTM:   A234 WPB

ASME:   B16.9, B.11

NACE:    MRO175

MSS:      SP-83, SP-95

Chemical Composition%

Fittings made from bar or plate may have 0.35 max carbon.

Fittings made from forgings may have 0.35 max Carbon and 0.35 max Silicon with no min.

For each reduction of 0.01% below the specified Carbon maximum, an increase of 0.06% Manganese above the specified maximum will be permitted, up to a maximum of 1.35%.

The sum of Copper, Nickel, Niobium, and Molybdenum shall not exceed 1.00%.

The sum of Niobium and Molybdenum shall not exceed 0.32%.
