China Supplier ASTM A53 Carbon Welded Steel Tube Welded Structure Pipe
Welded steel pipe for structure is used in steel structure, bridge support, building structure pipe, pile foundation pipe, etc.Because the structure of the pipe needs a lot of pressure and pressure capacity, the general use of wall thickness is greater than 8mm.The main material of the structure pipe is carbon steel.The main parameters of the welded steel tubes used in the structure are diameter, wall thickness, length and welding technology.Welded steel pipes for export shall be beveled, painted and capped.The welded steel tubes for the structure are made of double-sided submerged arc welding or high-frequency welding.
