High frequency steel tube mill is designed to produce round tube diameter of 60–140mm, and wall thickness of 1.5-4.0mm.
The High frequency steel tube mill is designed for forming pipes and tubes on one continuous line with steel strip, which was slit by slitting line to fit pipe or tube diameter. 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.
The application of advanced aperture technology, PLC automatic control system and
Digital speed regulating unit ensure that the production line works reliably and operates and maintains easily.
