GB / T3091 ERW Carbon Steel Pipe Use In Various Engineering Purposes, Fencing, Scaffolding Etc

Electric Resistance Welded pipe is used for welding pipe. Straight seam high frequency welded pipe has the characteristics of relatively simple process and rapid continuous production. It is widely used in civil construction, petrochemical industry, light industry and other departments.Used for making various engineering components and light industrial products.

Electric Resistance Welded is based on the principle of electromagnetic induction and the skin effect, proximity effect and eddy current thermal effect of ac charge in the conductor, so that the steel at the edge of the weld is partially heated to the melting state, and then the butt weld is extruded by the roller to achieve crystal indirect fusion, so as to achieve the purpose of weld welding.High-frequency welding is a kind of induction welding (or pressure contact welding), it does not need weld filler, no welding spatter, welding heat affected zone is narrow, beautiful welding molding, good welding mechanical properties, and other advantages, so it has been widely used in the production of steel pipe.

The Round Carbon ERW Steel Pipe adopts the carbon steel with high strength which is available to meet the ERM specification to make sure that it can work steadily and consistently.

Designed with the resistance to corruption, water, oxygen and dust, it is convenient to maintain and clean, which is available to maintain original after the long-term use. And it is endurable with prolonged life circle that it can be used for a long time.
