ASTM A691 GR.5CR welded pipes offer excellent corrosion resistance, high strength, & good creep resistance at elevated temperatures. The addition of chromium enhances their resistance to oxidation & scaling, making them suitable for applications in various industries, including petrochemical, power generation & refineries.

ASTM A691 GR.5CR welded pipes are manufactured using the electric-fusion-welding (EFW) process. This involves the fusion of two or more materials by heating them to a molten state & then allowing them to solidify to form a single, continuous pipe. The process ensures a strong and reliable weld.

ASME SA 691 GR.5CR welded pipes are available in a range of sizes typically ranging from 16 inches to 120 inches in diameter. The pipes are specified by their nominal pipe size (NPS) and schedule which indicates the wall thickness. They are manufactured in accordance with ASTM A691 specifications.

Yes, ASME SA 691 GR.5CR welded pipes are specifically designed for high-pressure applications. They are suitable for conveying fluids under high pressure & are commonly used in piping systems for power plants, oil and gas refineries & other industries where high-pressure conditions are present.
