ASTM A672 Grade J80 Pipes, EFW Steel Pipes, High-Pressure Alloy Pipes, Manganese-Molybdenum Pipes, ASTM A533 Pipes.
Kwality Steelage Pvt Ltd, a prominent manufacturer, supplier, and exporter based in Mumbai, India, specializes in providing ASTM A672 Grade J80 Electric Fusion Welded (EFW) Steel Pipes. These high-performance pipes are specifically engineered for high-pressure services at moderate temperatures. Fabricated using manganese-molybdenum quenched and tempered steel, as per ASTM A533 Cl-1B standards, these pipes exhibit exceptional strength, reliability, and resistance to mechanical stress, making them suitable for demanding applications in industries such as oil and gas, petrochemicals, and power generation.
ASTM A672 Grade J80 pipes are available in nominal sizes ranging from 1/2 inch to above 3 inches, with customizable thickness options to meet specific operational needs. Lengths can be tailored to requirements, including standard options like 3 meters, 6 meters, 12 meters, and up to 30 meters. These pipes are precision-engineered and undergo rigorous quality assurance measures, including chemical and mechanical property testing, ensuring adherence to the highest industry standards. Their chemical composition features 0.25% Carbon, 1.62% Manganese, and up to 0.64% Molybdenum, providing superior corrosion resistance and tensile strength.
The manufacturing process incorporates advanced Electric Fusion Welding (EFW) technology, ensuring uniform weld quality and seamless performance under high-pressure conditions. These pipes are offered in various classes, including Class 10 to Class 53, allowing clients to select the ideal variant based on radiographic, pressure testing, and heat treatment requirements. Supplementary testing, such as Charpy V-notch impact tests, further guarantees their reliability in critical applications. Available finishes include plain, beveled, and threaded ends, with protective options like shrink wrapping, jute wrapping, and wooden boxes to ensure safe transportation and handling.
The mechanical properties of ASTM A672 Grade J80 pipes include a minimum tensile strength of 485 MPa, a yield strength of 275 MPa, and an elongation range of 20-30%, making them highly durable and adaptable. These pipes are extensively used for fluid transportation, boiler components, and superheater systems across sectors requiring optimal performance under extreme conditions. Advanced surface treatments like varnishing, black painting, and anti-corrosion coatings further enhance their operational longevity.

ASTM A672 Grade J80 pipes are subjected to precise manufacturing and heat treatment processes to ensure superior performance. Quenching and tempering (Q&T) are integral steps in their production, delivering enhanced mechanical properties and structural integrity. For pipes with thicknesses exceeding 13 mm, Post-Weld Heat Treatment (PWHT) is recommended to minimize residual stresses and improve durability. For thinner sections, preheating to 120°C is typically sufficient, ensuring reliable performance under high-pressure conditions.
