45 HF Welded Pipe Mill

I Summary:

45-2.0 High frequency welded pipe production line is used to produce EMT tube and cold bending profile steel with material of mild steel & low carbon steel of cold and hot roll carbon steel and galvanized roll carbon steel (CR, HR & GI) in the fields of metallurgy, construction, traffic, mechanism and vehicle. It can make steel strip of a certain specification into round pipe and square and rectangular pipe through cold bending forming and high frequency welding. The forming and sizing machine is designed well, so it can produce the perfect pipe.
