Kwality Steelage Pvt Ltd, a trusted manufacturer, supplier, and exporter based in Mumbai, India, offers ASTM A671 Gr CJ108 Electric Fusion Welded (EFW) Pipes, engineered for demanding industrial applications. These pipes, crafted from quenched and tempered alloy steel as per ASTM A517 standards, provide exceptional durability, strength, and reliability. Designed for low-temperature and atmospheric applications, they cater to industries such as petrochemicals, oil and gas, power plants, and marine engineering with unparalleled efficiency.
ASTM A671 Gr CJ108 Pipes are available in versatile sizes, lengths, and finishes to meet diverse project requirements. With diameters ranging from ½ inch to >3 inches, lengths of 3 meters, 6 meters, and 12 meters, and customizable thicknesses, these pipes offer flexibility for various use cases. The surface finishes include mill-finished, sand-blasted, brushed, anodized, and polished, with options for black and other coatings. Each pipe undergoes rigorous quality checks, including radiographic and pressure testing, ensuring dimensional accuracy and reliability.
Made from high-quality alloy steel, these pipes boast superior mechanical and chemical properties. They have a tensile strength of 515-655 MPa, yield strength of at least 240 MPa, and elongation rates of 21-25%, making them ideal for high-stress and high-pressure applications. The chemical composition, with controlled amounts of carbon, manganese, and silicon, further enhances their strength, ductility, and corrosion resistance, ensuring a long service life.
Widely used in petrochemical plants, boiler systems, marine engineering, and structural applications, ASTM A671 Gr CJ108 Pipes deliver exceptional performance under extreme conditions. Their ability to resist low-temperature cracking and maintain strength under pressure makes them a preferred choice across industries. Whether for fluid transportation, saltwater applications, or structural support, these pipes stand out for their unmatched performance and reliability.
