ASTM A672 Grade H80 Pipes, EFW Steel Pipes, High-Pressure Steel Pipes, Manganese-Molybdenum Pipes, and ASTM A302 Pipes.
Kwality Steelage Pvt Ltd, headquartered in Mumbai, India, stands out as a leading manufacturer, supplier, and exporter of ASTM A672 Grade H80 Electric Fusion Welded (EFW) Steel Pipes. Designed to meet the stringent requirements of high-pressure applications at moderate temperatures, these pipes are fabricated using manganese-molybdenum-normalized steel, conforming to ASTM A302 standards. With unmatched structural integrity, they cater to industries such as oil and gas, petrochemicals, power plants, and boiler systems, ensuring durability and reliability under challenging operating conditions.
ASTM A672 Grade H80 pipes are available in outer diameters ranging from 12 inches to 64 inches, with wall thickness options from 2mm to 60mm, covering a wide spectrum of schedules, including SCH10, SCH40, SCH80, and SCH160. These pipes can be customized to lengths of 5 meters to 14 meters, with end finishes such as plain or beveled, protected with plastic caps. Their robust surface treatments, including bare, black painting, varnished, or advanced anti-corrosion coatings like 3PE and FBE, enhance durability and resistance to harsh environments.
The manufacturing process includes precision-driven hot-rolled or cold-drawn techniques, followed by comprehensive testing. Each pipe undergoes eddy current, ultrasonic examination, and hydrostatic testing to ensure structural soundness and compliance with API and ASTM standards. The mechanical properties of Grade H80 pipes include a tensile strength of 485 MPa and a yield strength of 275 MPa, with elongation ranging between 20% and 30%, making them highly resilient for high-pressure fluid transmission and structural applications.
With diverse applications, ASTM A672 Grade H80 pipes are indispensable for conveying oil, gas, and water across refineries, marine industries, and chemical plants. The supplementary requirements, such as Charpy V-notch impact testing and bend tests, further affirm their suitability for critical use cases. Offered in multiple classes, including Class 10, 20, 30, and up to 53, these pipes can be normalized, tempered, or quenched based on specific project requirements.

Welding ASTM A672 Grade H80 pipes demands precision to ensure durability under high-pressure applications. For wall thicknesses above 13 mm, Post-Weld Heat Treatment (PWHT) is highly recommended to reduce residual stresses and improve mechanical stability. For thinner sections, preheating to 120°C is generally sufficient. Stress-relieved, normalized, and tempered options are available to meet specific operational demands.
| Feature | H80 | Other Grades (e.g., B60) |
|---|---|---|
| Material Composition | Manganese-Molybdenum | Plain Carbon Steel |
| Applications | High-Pressure, Moderate Temperatures | Low to Medium-Pressure |
| Heat Treatment Requirements | Normalized | Varies |
