Sew straight into the steel pipe

Description: Large diameter straight seam steel pipes generally refer to straight seam steel pipes with an outer diameter of 500mm or more. Currently, the double weld large diameter can reach 2020mm, and the single weld large diameter can reach 1220mm.

Large diameter straight seam steel pipes are a good choice for large-scale pipeline engineering, water and gas transmission engineering, and urban pipeline network construction. The West East Gas Pipeline uses 200000 tons of this type of steel pipe, with broad market prospects.

Application range of large-diameter straight seam steel pipes:

Large diameter straight seam steel pipes are mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, and urban construction.
