Fittings are used in the piping system to forge connections. While different fittings have different secondary purposes, ASME B16.9 Fittings are a means of modifying the existing piping system. This Standard covers overall ASME B16 9 Pipe Fittings Dimensions, as well as tolerances, ratings, testing, and markings for wrought type butt-welding fittings. These factory produced fittings are available in sizes NPS 1/2 through 48. Commonly, the ASTM Pipe Fittings Materials includes Steel, Stainless Steel, Carbon steel, Cast iron, Ductile iron, Iron, Brass, Copper, Aluminium, Rubber, Plastic etc. Depending on the application or the requirements of the buyer, a manufacturer is to produce ASME B16.9 Butt-Welding Pipe Fittings using materials that are relevant to the particular specification.

For instance, if corrosion resistance, high mechanical strength and superior mechanical properties with heat resistance properties are required, several stainless steel grades may be used to produce ANSI B16.9 Welded Fittings. Typically industries such as the chemical, textiles, petroleum, food and beverage, sugar industry, fluid power, nuclear power, electronic and pulp and paper plants use the ASME B16.9 Material Weight Chart.
