Q195 Q215 Q235 Q345 Structural ERW Carbon Steel Pipe

Structural ERW Carbon Steel Pipe Use In Various Engineering Purposes, Fencing, Scaffolding Etc

Both electric resistance welded (ERW) and submerged arc welded (SAW) tube or pipe is mostly produced by first forming steel sheet or plate into a cylinder and then welding the longitudinal gap to form a seam.

With ERW the seam is progressively welded using a combination of heat and pressure. Resistance to electric current generates heat in the weld locality, taking the temperature of the steel to just below its melting point. Simultaneously, mill rolls located around the pipe force the two edges of the formed sheet/plate together to join them.

Steel structure, with its own advantages, in the construction of the proportion is more and more big, the steel structure is also made great breakthrough. Steel tube structures with its unique advantages to get the favour of people, is mainly used in some large public buildings;In industrial workshop column and roof truss, light steel structure and potential application of residential steel structure is very wide;Such as Bridges, DAMS, offshore platform bearing with columns, large span steel structure building structure and electric tower mast structure has broad prospects.
