ASTM A672 Grade H75 Pipes, EFW Pipes, High-Pressure Steel Pipes, ASTM A302 Pipes, Manganese-Molybdenum Steel Pipes.
Kwality Steelage Pvt Ltd, based in Mumbai, India, is a prominent manufacturer, supplier, and exporter of ASTM A672 Grade H75 Electric Fusion Welded (EFW) Steel Pipes. These pipes are meticulously crafted from pressure vessel quality plates, ensuring outstanding performance in high-pressure applications at moderate temperatures. Designed to meet ASTM A672 standards, they feature manganese-molybdenum-normalized steel construction, as specified in ASTM A302 Grade A, delivering exceptional strength, weld integrity, and durability. Their versatility and adherence to stringent quality requirements make them a preferred choice for industries such as oil and gas, petrochemicals, and power generation.
ASTM A672 Grade H75 pipes are available in sizes ranging from 16 inches to 60 inches in diameter, with wall thicknesses up to 3 inches, catering to a broad spectrum of industrial needs. These pipes are engineered with precision and undergo rigorous testing, including transverse tensile properties, radiographic examination, and guided weld bend tests. The heat treatment process, which includes normalization and tempering at temperatures up to 1800°F (980°C), ensures optimal mechanical properties, making them suitable for demanding applications. With various classes available, from Class 10 to Class 53, these pipes are tailored to meet specific radiography and pressure testing requirements.
Known for their superior chemical composition and mechanical properties, these pipes are designed to withstand challenging environments. Manganese and molybdenum contribute to their excellent corrosion resistance and high-pressure strength. The pipes undergo product analysis to ensure compliance with the chemical and welding specifications, providing unmatched reliability and consistency. Their robust construction and reliable performance make them an ideal choice for critical applications in power plants, transporting high-pressure fluids in the oil and gas sector, and structural projects requiring heavy-duty materials.

Welding ASTM A672 Grade H75 pipes requires careful handling to maintain mechanical integrity. Post-Weld Heat Treatment (PWHT) is recommended for pipes with wall thicknesses over 13 mm to reduce residual stress and prevent cracking. For thinner sections, preheating to 120°C is generally sufficient. This ensures robust connections and optimal performance under high-pressure conditions.

|---|---|---|
| Material Composition | Manganese-Molybdenum | Plain Carbon Steel |
| Applications | High-Pressure, Moderate Temperatures | Low to Medium-Pressure |
| Heat Treatment Requirements | Normalized | Varies |
