API 5L High-Frequency Longitudinal ERW Pipes strictly comply with the American API 5L standard. The ERW (Electric Resistance Welding) process endows these steel pipes with high dimensional accuracy and superior weld quality during production. High-frequency longitudinal welding technology ensures weld seam uniformity and density, enhancing the pipe's overall strength and reliability.
Typical specifications include:
Outside Diameter: 21.3–762 mm
Wall Thickness: 2.0–140 mm
enabling adaptability to diverse engineering requirements.
