ASTM A672 is a specification that covers electric-fusion-welded (EFW) steel pipes used for high-pressure service at moderate temperatures. These pipes are primarily designed for conveying fluids like water, oil, and gas in various industrial applications. The "A" in ASTM A672 indicates that it's a specification for carbon steel, and the number following it signifies the minimum yield strength of the steel. The pipes under this specification are produced using a welding process that involves the fusion of steel plates through an electric arc. This process ensures the integrity and strength of the welded joints. ASTM A672 carbon steel EFW pipes come in several grades, each denoting different mechanical properties and chemical compositions. These pipes are often used in applications where high strength and resistance to corrosion are required.
