introduction
ASTM A671 Carbon Steel EFW Pipe is a carbon-based stainless steel alloy containing elements such as carbon, silicon, and manganese, as well as trace amounts of phosphorus and sulfur.
Its mechanical properties are improved by alloying elements, with a yield strength of approximately 240 MPa and a tensile strength ranging from 450 MPa to 585 MPa. Pipe ends are available in a variety of styles, including beveled, flat, grooved, square cut, etc. with plastic protective caps. Threaded ends and splice ends are also available.
Surface treatment includes coatings such as EP, PE PP, FBE, anti-corrosion oil and black paint, or painting or galvanizing to improve corrosion resistance. ASTM A671 EFW Pipes are used in a wide range of applications including shipbuilding, oil and gas, fertilizers, manufacturing and other industries to transport fluids and gases from the site to the factory. Pipes undergo several tests such as hydrostatic testing or ultrasonic testing, eddy current testing and non-destructive testing, and their physical and chemical properties are checked.
