Welded steel tube mill
Brief introduction
Welded steel tube mill is designed to produce round tube diameter of 25–80mm, and wall thickness of 1.2-4.0mm.
The Welded 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.
Application
Furniture/ornamental for high quality tube with aesthetic surface
Mechanical tube for precision tube as well as for high-resistant material
Structural high productivity and good mechanical properties
Water/gas to comply with the norms
Heat exchanger for pressure, boiler and heat exchanger tubing
