I. Summary

ERW610 high-frequency welded pipe production line is the special equipment providing longitudinally welded pipe and cold formed steel for industries such as metallurgy, construction, transportation, machinery, vehicles and so on. Taking cold or hot-rolled steel as raw materials, through cold-formed and high-frequency welding method produce the suitable round tube.

Material of the coil: low carbon steel and low alloy steel(σb≤827Mpa,σs≤690Mpa.)
