ASTM A672 Grade J90 pipes are available in sizes ranging from 1/2 inch to above 3 inches, with customizable wall thicknesses to meet specific requirements. Standard lengths include 3 meters, 6 meters, 12 meters, and even up to 30 meters, ensuring flexibility for diverse industrial needs. The chemical composition features a maximum of 0.25% Carbon, up to 1.62% Manganese, and 0.64% Molybdenum, offering superior resistance to wear, corrosion, and extreme pressure conditions. These properties make them suitable for transporting fluids, gases, and other critical substances.

The manufacturing process incorporates advanced Electric Fusion Welding (EFW) techniques to ensure seamless construction and superior weld integrity. Available in multiple classes (Class 10 to Class 53), these pipes undergo rigorous testing, including radiographic examination and hydrostatic pressure tests, to ensure compliance with stringent quality standards. Heat treatment processes like quenching and tempering enhance their mechanical properties, with a tensile strength of 485 MPa and a yield strength of 275 MPa, providing reliable performance in demanding environments.

To meet specific project requirements, ASTM A672 Grade J90 pipes are offered with various end types, including plain, beveled, and threaded finishes. Surface treatments such as bare, painted, or advanced anti-corrosion coatings like 3PE and FBE further extend their operational life. These pipes also conform to strict dimensional tolerances, maintaining ±1% accuracy in diameter and ±10% in wall thickness, ensuring precise installation and optimal performance under high-stress conditions.

Kwality Steelage Pvt Ltd ensures that all ASTM A672 Grade J90 EFW pipes meet the highest quality benchmarks while offering competitive pricing and custom solutions.

Welding and Heat Treatment for ASTM A672 Grade J90 Pipes

ASTM A672 Grade J90 pipes are manufactured with precise attention to heat treatment to enhance their mechanical properties. Quenching and tempering (Q&T) are key steps, ensuring improved strength and durability. For wall thicknesses exceeding 13 mm, Post-Weld Heat Treatment (PWHT) is recommended to relieve residual stresses and prevent cracking. Thinner sections generally require preheating to 120°C, ensuring reliable performance in high-pressure environments.

Differences Between ASTM A672 Grade J90 and Other Grades

Feature J90 Other Grades (e.g., B60)
Material Composition Manganese-Molybdenum (Q&T) Plain Carbon Steel
Applications High-Pressure, Moderate Temperatures Low to Medium-Pressure
Heat Treatment Requirements Quenched and Tempered Varies
