HGF300high-frequency welded pipe production line isthe special equipment providinglongitudinally welded pipeand cold formed steel forindustriessuch asmetallurgy, construction, transportation, machinery, vehicles andso on.Used traditional square technology to produce square and rectangle pipe.Takingcold or hot-rolled steel as raw materials,throughcold-formed and high-frequency welding method to producethe suitable roundtube.Material of the coil: low carbon steel (σb≤500Mpa,σs≤235Mpa.)Strip Steel: Q235 (max.)
Finished product will be of round pipe, square and rectangle pipe.
