A671 Gr CJ107

These pipes are electric fusion welded (EFW) and made from pressure vessel quality plates, offering wall thicknesses up to 250 mm and diameters between 3/4 inch and 100 inches. ASTM A671 Gr CJ107 Pipes are quenched and tempered as per ASTM A517/A517M standards, providing excellent mechanical strength and durability. They are available in finishes such as polished, anodized, mill finished, and brushed, making them adaptable to various applications. Standard lengths include 3, 6, and 12 meters, with custom options available upon request. Packaging options like shrink wrapping and wooden boxes ensure safe transportation.

Widely used across several industries, these pipes excel in environments where performance and safety are critical. In the petroleum and oil sectors, they ensure smooth fluid and gas transmission. Marine engineering applications rely on their corrosion resistance under harsh environmental conditions. Power plants utilize these pipes for high-pressure and high-temperature operations, while chemical industries benefit from their robustness against aggressive chemical reactions.

ASTM A671 Gr CJ107 Pipes deliver superior mechanical properties, including a minimum yield strength of 260 MPa and tensile strength between 485 and 620 MPa. Their chemical composition ensures low carbon content (0.31% max) and manganese up to 1.30%, promoting ductility and thermal stability. Advanced heat treatments such as normalization, tempering, and stress relieving enhance the pipes’ toughness and reliability for long-term use in challenging conditions.

These pipes offer extensive customization options, including a range of classes (Class 10 to Class 73) to suit specific heat treatment and testing needs. Coatings like epoxy and 3LPE enhance corrosion resistance, extending service life. Comprehensive testing, including Charpy impact tests, radiographic examinations, and ultrasonic inspections, ensures compliance with global safety and quality standards.
