ERW Carbon Steel Welded Pipe Production Line

we are offering erw carbon steel welded pipe production line.
electric resistance welded (erw) tubes are made by forming the steel strip into a tubular round section by progressive movement through a set of specially designed rolls. the butted ends of the strip are welded by high frequency induction welding process without any filler material. the hot weld-flash formed due to welding is removed internally (fin-cut) and externally by the deburring units. turks head and sizing rolls provided at the end of the tube mill ensure straightening and sizing of the tubes into required sections like rectangular, square, elliptical and oval. the tubes are cut into required length and undergo annealing, pressure testing, eddy current testing, straightening or cutting depending upon the applications.
erw carbon steel tube mill production is designed to produce round tube, square rectangular pipe, oval pipe and special pipe like ltz section welding featured with high efficiency and reliable.
using high frequency induction heating, this line is capable of producing section material of various diameters and sizes by squeezing weld seam together into closed shape.
