114 Tube mill Line High‐frequency welded tube mill line is designed to produce round tube diameter of 25.4 – 114 mm, and wall thickness of 0.8 ‐4.0 mm. This line utilizes roll forming to process steel strip into various shapes. 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 British Eurasia Digital speed‐regulating unit ensure that the production line works reliably and operates and maintains easily.
