ASTM A672 GR L70, EFW Pipes, Carbon Steel Pipes, High-Pressure Steel Pipes, Kwality Steelage , ASME SA672 L70 Pipes, Oil and Gas Industry Pipes
Kwality Steelage Pvt. Ltd., a trusted name in steel manufacturing and exporting based in Mumbai, India, offers high-quality ASTM A672 GR L70 EFW Pipes designed to meet the demanding needs of industrial applications. These pipes, crafted from pressure vessel-grade plates, are ideal for high-pressure applications at moderate temperatures. Known for their superior strength, excellent ductility, and enhanced corrosion resistance, ASTM A672 GR L70 pipes are extensively utilized in industries such as oil and gas, offshore drilling, power plants, and chemical processing.
ASTM A672 GR L70 pipes are electric-fusion-welded (EFW), delivering robust performance for high-pressure services. These pipes have a yield strength of 37 MPa and a tensile strength range of 65 MPa, ensuring durability and resistance under extreme conditions. Chemically, the composition includes a maximum of 0.25% carbon, 0.98% manganese, 0.64% molybdenum, and 0.45% silicon, making them highly suitable for structural and transmission needs. The pipes are available in diameters from 16 inches to 100 inches and wall thicknesses up to 250 mm, with customizable lengths ranging from 5 to 13 meters.
ASTM A672 GR L70 EFW pipes are versatile, finding applications in low-temperature services, oil and gas transportation, and offshore platforms. Their low thermal conductivity compared to alloy steels enhances their energy efficiency in various environments. The pipes offer excellent weldability and toughness, making them suitable for complex fabrication and assembly processes. They are commonly used for transmitting water, oil, and gas, along with structural applications in power plants and refineries.
To optimize performance, ASTM A672 GR L70 pipes undergo rigorous heat treatment processes, including normalizing, quenching, and tempering, tailored to the application’s requirements. Coating options like epoxy, 3LPE, and anti-corrosion oil further enhance their durability and resistance to harsh environments. Testing methods such as radiographic examinations and ultrasonic testing ensure the highest quality standards are maintained.
With a commitment to delivering excellence, Kwality Steelage Pvt. Ltd. ensures that all ASTM A672 GR L70 EFW pipes meet international standards such as ASME SA672 and ASTM specifications. The pipes are inspected and certified under stringent third-party audits and come with comprehensive documentation, including EN10204 3.1 and 3.2 certifications. Our products are competitively priced, making them accessible for projects across sectors.

ASTM A672 GR L70 EFW pipes undergo processes like normalizing, stress-relieving, and tempering, which optimize their mechanical properties. Welding requires care to prevent residual stress, and post-weld heat treatment (PWHT) is recommended for enhanced durability. Coatings like epoxy, varnish, or anti-corrosion oil are applied to extend the pipe’s life and protect against environmental damage.
