Latest company news about ASTM A672 Carbon Steel EFW Pipe

ASTM A672 Carbon Steel EFW Pipe

ASTM A672 Pipe comes under a specification that covers pipes of larger diameter sizes. The diameters range from 16 inches to mostly 100 inches. GNEE is a leading supplier of the ASTM A672 Pipe types. There are different grades of pipes within the same specification based on the chemical composition. The pipes mostly have carbon, silicon, manganese, phosphorus and sulfur in the composition with varying quantities for various grades. The Tubo ASTM A672 grades have different mechanical properties as well.

Most of them have minimum yield strengths of 240MPa and minimum tensile strength in the range of 450 to 585MPa. The applications of the A672 efw pipes are seen mostly in the petroleum, petrochemical, engineering, ship building, marine, food processing and in other oil and gas industrial applications. As one of the leading A672 pipe manufacturers we produce the pipes for all application types, different grades and dimensions as well. The pipes are suitable for high pressure service in moderate temperatures. Therefore the A672 ASTM Welded pipe is also used in boiler, heat exchanger and condenser components where appropriate.
