Structural Welded Steel Pipe

Structural steel pipe applicant in steel structure bridge support, building structural tube, pipe pile foundation, etc. Due to structural tube takes a lot of pressure and pressure ability, generally USES wall thickness greater than 8 mm. Give priority to the main material is carbon steel structural tube. Structure with the main parameters of the welded carbon steel pipe diameter, wall thickness, length and welding technology, whether the need for surface anti-corrosion insulation treatment. Exports of welded steel pipe need to groove, brush paint, pipe cap. Structure with welded steel pipe made of double-sided submerged arc welding or high frequency welding.
