Durable and Reliable ASTM A671 Gr CJ104 Pipes for Industrial Applications
ASTM A671 Gr CJ104 pipes are a versatile solution for industrial and commercial applications requiring high-pressure and low-temperature capabilities. Manufactured by Kwality Steelage Pvt Ltd in Mumbai, India, these pipes are crafted from alloy steel, quenched and tempered to deliver exceptional durability and mechanical strength. The pipes are available in customizable lengths, ranging from 3 meters to 30 meters, with sizes tailored to meet specific project requirements. Their versatility is further enhanced by various surface finishes, such as sand-blasted, polished, mill-finished, and anodized, making them ideal for use in petroleum, oil, and gas industries.
These pipes adhere to the ASTM A517/A517M specifications, ensuring they meet the highest standards for electric-fusion-welded (EFW) pipes. The alloy steel composition provides exceptional weldability, toughness, and resistance to stress cracking, which makes them suitable for boiler and superheater applications. Available in standard and customized dimensions, ASTM A671 Gr CJ104 pipes are designed to withstand harsh environments while maintaining structural integrity. This makes them a preferred choice for industries ranging from petrochemical plants to marine applications.
Kwality Steelage Pvt Ltd is a globally recognized supplier, stockist, and exporter of ASTM A671 Gr CJ104 pipes, offering them in a variety of grades and classes, including Class 10 through Class 73. These classifications cover different heat treatments, such as stress-relieved, normalized, and quenched and tempered. The pipes are rigorously tested, including radiographic and pressure testing, to ensure they conform to mechanical properties like tensile strength of up to 620 MPa and yield strength starting from 205 MPa. Such robust characteristics make these pipes indispensable for critical infrastructure.
One of the standout features of ASTM A671 Gr CJ104 pipes is their adaptability for custom coatings and finishes, including epoxy coatings and 3LPE, to enhance corrosion resistance. They are available in both plain and beveled ends, facilitating ease of installation in diverse piping systems. Additionally, these pipes meet ISO certification standards and are supported by NABL-approved laboratory test certificates, ensuring uncompromising quality and reliability.

ASTM A671 Gr CJ104 pipes undergo advanced electric fusion welding to enhance their mechanical properties. To ensure durability, these pipes are quenched and tempered during the manufacturing process. Post-weld heat treatment (PWHT) is recommended for pipes with wall thickness exceeding 13 mm, maintaining structural stability. For thinner sections, preheating to 150°C is sufficient, reducing residual stress and improving weld performance.
These pipes are widely used in industries such as:
