HGF200 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.
Used new technology to produce square and rectangle pipe directly.
Taking cold or hot-rolled steel as raw materials, through cold-formed and high-frequency welding method to produce the suitable pipe.
Material of the coil: Low carbon steel, max. Q355.
