Economical Large-Diameter Pipe
Spiral submerged-arc welded pipe reaches OD 219-3500mm with wall 6-28mm and lengths to 30m - the economical choice for water transmission, piling and low-to-medium pressure lines at volume.
Standards and Grades
Production covers SY/T5037, GB/T9711 and API 5L grades A, B and X42-X70 in Q235B and Q355B. LSAW longitudinal pipe (OD 325-1422mm, wall 6-40mm) is available where the specification requires it.
Buyer Tip: Confirm Line-Pipe vs Piling Duty
Piling and structural use accepts SY/T5037 class material at a lower cost; water and oil transmission usually requires GB/T9711 or API 5L PSL levels. Confirm the duty class before comparing prices.
