AP I 5L ERW (Electric Resistance Welded) line pipe is a high-performance steel pipe designed for oil, gas, and hydrocarbon transportation in demanding environments. Manufactured to AP I 5L (American Petroleum Institute) specifications, these pipes are available in Grades B, X42, X46, X52, X56, X60, X65, and X70, with low sulfur content (≤0.12%) to enhance weldability and corrosion resistance.

Available in 8.625" to 20" diameters, these pipes are widely used in onshore/offshore pipelines, refineries, and petrochemical plants, ensuring high strength, durability, and leak-proof performance.

 

Key Features & Benefits

 High-Strength Material - Suitable for high-pressure oil & gas transmission.
 ERW Construction - Precision electric resistance welding ensures consistent wall thickness & structural integrity.
 Low Sulfur Content (≤0.12%) - Improves weldability & corrosion resistance.
 AP I 5L Compliance - Meets PSL1 & PSL2 requirements for pipeline safety.
 Cost-Effective - ERW process reduces production costs compared to seamless pipes.
