Straight Seam Welded Pipe
Produced by forming steel coil or plate into a tubular shape and welding the longitudinal seam using high-frequency ERW (for small to medium diameters) or submerged arc welding LSAW (for large diameters).
Spiral Welded Pipe
Produced by helically forming steel coil into a tubular shape and welding the spiral seam using submerged arc welding (double-sided or single-sided). Features wide diameter range, good dimensional consistency, high strength, and cost-effective production for large diameters.
