Products We Offer

ASTM A672 C70 cl 22 Pipe

There are various classes that are available in ASTM A672 grade. Pipes made up of these different classes have different qualities. ASTM A672 C70 cl 22 Pipe is one such class that is made up of pressure vessel quality plates. These pipes are widely used in high-pressure applications at moderate temperatures. Heat treatment may or may not be performed on these pipes to attain the desired properties. ASTM A672 Grade C70 ERW Pipe displays good workability with wall thickness that is thin. These pipes are rugged in structure and are sturdy with accurate dimensions.

ASTM A672 Gr c70 cl 12 EFW Pipe is also resistant to rust, and general corrosion. These pipes can be machined, sandblasted, galvanized, heat-treated, shot blasted and drawn. They are available in various shapes, sizes, and dimensions. CS A672 c70 cl11 Welded Pipe is available in different thicknesses ranging from 2mm to 60mm and the diameter that ranges between 12 inches to 64 inches. The pipes are usually plain, beveled, or threaded. The composition of elements used in ASTM A672 Gr. c70 cl.22 Round Pipe enhances the ductility and toughness of the product.

A672 c70 class 22 SAW Pipe produced by us are usually as per the international standards since we cater not only to domestic but international customers as well. We even customize these products as per the customers' specific requirements. ASTM A672 C70 pipe produced by us are supplied at affordable prices.
