ASME B16.9 Buttweld Pipe Fittings Dimensions

Comprehensive dimensional data for factory-made wrought buttwelding fittings.

What is the ASME B16.9 Standard?

The ASME B16.9 standard covers overall dimensions, tolerances, ratings, testing, and markings for factory-made wrought buttwelding pipe fittings in sizes NPS 1/2 through NPS 48 (DN 15 through DN 1200). It is the globally accepted standard for ensuring that fittings like elbows, tees, reducers, and caps seamlessly weld to pipes and handle high-pressure industrial applications.

At Creative Piping Solutions, we manufacture and supply premium quality ASME B16.9 Buttweld Fittings designed for precision, durability, and leak-proof performance in critical pipelines.
