High Frequency Carbon Steel Tube Mill

Brief Introduction of High Frequency Carbon Steel Tube Mill

The High frequency carbon steel tube mill line 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.

Applications of High Frequency Carbon Steel Tube Mill

Furniture/ornamental for high quality tube with aesthetic surface
Automotive to comply with the high demand standard of automotive industry
Mechanical tube for precision tube as well as for high-resistant material
Structural high productivity and good mechanical properties
Conduit electric cables conduits
Water/gas to comply with the norms for
Heat exchanger for pressure, boiler and heat exchanger tubing
API for oil and natural gas
Steel profiles
