ASTM A671 Carbon Steel EFW Pipe Manufacturer, Supplier, Exporter & Stockist in india
ASTM A671 Carbon Steel Electric Fusion Welded (EFW) Pipe is a standardized specification that governs the manufacturing and use of electric-fusion-welded steel pipes designed for atmospheric and lower-temperature service. These pipes are commonly used in industries and applications where the pipes are subjected to less extreme temperatures and atmospheric conditions. ASTM A671 encompasses a wide range of grades and classes, providing options suitable for various operating conditions. Grade and Class: ASTM A671 EFW Pipes come in various grades and classes, such as A671 CC60/CC65/CC70, and many more, each with distinct properties to meet specific service requirements. The choice of grade and class depends on factors like temperature, pressure, and corrosion resistance.
Size and Wall Thickness: These pipes are available in a range of sizes, typically ranging from NPS 1/2 to NPS 100 (Nominal Pipe Size), and various wall thicknesses, including SCH 10, SCH 20, SCH 30, SCH 40, SCH 60, SCH 80, SCH 100, SCH 120, SCH 140, SCH 160, STD, XS, and XXS. The selection depends on the application's design and operational requirements. Manufacturing Method: ASTM A671 pipes are manufactured using the electric fusion welding process, which involves joining steel plates or coils by melting them together with the application of electrical energy. This method ensures the formation of strong and reliable welds. Application: These pipes are suitable for use in low-temperature service conditions and in atmospheres where the demands on the material are less severe. They are commonly used in applications such as process piping, refineries, chemical plants, and other industrial settings.
