ASTM A672 Grade J100 Pipes, EFW Steel Pipes, High-Pressure Steel Pipes, Manganese-Molybdenum Pipes, ASTM A533 Pipes.
Kwality Steelage Pvt Ltd, based in Mumbai, India, is a leading manufacturer, supplier, and exporter of ASTM A672 Grade J100 Electric Fusion Welded (EFW) Steel Pipes. These pipes are engineered for high-pressure applications at moderate temperatures, adhering to ASTM A533 Cl-3B standards. Crafted using manganese-molybdenum quenched and tempered (Q&T) steel, these pipes offer exceptional strength, durability, and resistance to mechanical stress. They are ideal for critical industries such as oil and gas, power generation, petrochemicals, and fluid transmission.
The ASTM A672 Grade J100 pipes come in nominal sizes ranging from 1/2 inch to over 3 inches, with wall thicknesses customizable up to 250 mm, depending on project requirements. Available in lengths of 3 meters, 6 meters, 12 meters, and even 30 meters, these pipes provide flexibility for various industrial applications. Their chemical composition includes a maximum of 0.25% Carbon, up to 1.62% Manganese, and 0.64% Molybdenum, ensuring superior corrosion resistance and strength. These attributes make them highly suitable for transporting fluids, gases, and other critical substances across long distances.
The manufacturing process leverages advanced Electric Fusion Welding (EFW) technology to ensure seamless construction and consistent quality. These pipes are offered in a wide range of classes, including Class 10 to Class 53, with options for stress-relieved, normalized, or tempered finishes to meet specific operational demands. Rigorous testing, such as radiographic and hydrostatic examinations, is conducted to ensure compliance with stringent industry standards. With a tensile strength of 550 MPa and a yield strength of 310 MPa, these pipes deliver reliable performance in high-pressure environments.
To meet diverse project needs, ASTM A672 Grade J100 pipes come with various end types, such as plain, beveled, or threaded finishes, and can be coated with anti-corrosion treatments like 3LPE, FBE, or epoxy coatings. Their dimensional tolerances are precise, with ±1% accuracy for outer diameter and ±10% for wall thickness, ensuring flawless installation. Additionally, optional value-added services such as galvanizing, sandblasting, and heat treatment are available for enhanced functionality and longevity.
Kwality Steelage Pvt Ltd ensures every ASTM A672 Grade J100 pipe meets the highest quality standards while offering competitive pricing. The company is committed to delivering customized solutions for global industrial needs. Contact us today to learn more about technical specifications, pricing, or to request a personalized quote.

ASTM A672 Grade J100 pipes are manufactured with precise heat treatment to enhance their durability and mechanical properties. The quenching and tempering (Q&T) process ensures superior tensile strength and resistance to stress. For wall thicknesses exceeding 13 mm, Post-Weld Heat Treatment (PWHT) is essential to reduce residual stresses and prevent cracking. For thinner sections, preheating to 120°C is recommended, ensuring robust performance in high-pressure applications.
