ERW pipe mill
The high frequency straight seam welded pipe mill is used to level the fixed strip after slitting line, and entry it to forming machine, bend to open pipe by rollers, melt the strip edges through the high frequency current,squeeze and weld the pipe to be closed by the squeeze roll. The high frequency pipe mill also called ERW pipe mill.
High frequency welded pipe mill is the special equipment producing welded steel pipe and profile pipe for industries such as metallurgy, construction, transportation, machinery and so on. Taking cold or hot rolled steel as raw materials, through cold formed and high-frequency welding to produce the round pipe, square pipe and rectangle pipe.
