ASTM A671 Carbon Steel EFW Pipe
ASTM A671 Carbon Steel Pipes are available in a range of sizes and thicknesses to suit different application requirements. The nominal pipe sizes can vary from NPS 1/2 inch to NPS 48 inch.
ASTM A671 EFW pipe is a carbon steel alloy containing elements such as carbon, silicon, and manganese, as well as trace amounts of phosphorus and sulfur. The mechanical properties of this alloy have been improved by adding alloying elements, with a high yield strength of approximately 240MPa and a tensile strength ranging from 450MPa to 585MPa.
ASTM A671electric resistance welded pipe ends are available in a variety of styles, including beveled, flat, grooved, square cut, etc., and are equipped with plastic protective caps. Also available are threaded and spliced ends. The surface treatment of this kind of pipeline includes coatings such as EP, PE PP, FBE, anti-corrosion oil and black paint, or spray painting or galvanizing to improve corrosion resistance.
ASTM A671 EFW steel pipe is widely used in several industries, including shipbuilding, oil and gas, fertilizers, manufacturing and other industries. It is used to transport fluids and gases from the site to the factory. In order to ensure the quality and performance of pipelines, a number of tests are required, including hydrostatic testing or ultrasonic flaw testing, eddy current testing and non-destructive testing, to check their physical and chemical properties.
