Double Sides Submerged Arc Welded Pipe

The double sides submerged arc welded pipe has large diameter, works with high transportation efficiency and is conducive to saving the investment of laying the pipeline. It is mainly applied for water supply engineering, petrochemical industry, chemical engineering, electric power industry, agricultural irrigation and urban construction.

Application Range
1. Fluid delivery in water supply and drainage
2. Gas delivery for coal gas, vapor and liquefied petroleum gas
3. Structural use as pile pipe and bridge
4. Tube for wharf, road, building structure, etc.
