Seamless steel cold-rolled tubes

Seamless steel cold-rolled tubes

Seamless steel cold-rolled tubes are applicable in chemical, oil and food industry for machines parts and units production. The tubes are produced in accordance with TU 14-3-1941-1994, TU 14-3Р-134-2014 by cold rolling method or by cutting machining.

Material of seamless steel cold-rolled tubes

  • structural steel grade 20, 35, 35Г pursuant to TU 14-3-1941-94, TU 14-3Р-134-2014;
  • corrosion-resistant steel grade12Х18Н10Т, ultimate strength is up to 100 kilogram-force/mm2.

We provide

  • production of displaced tolerant zone tubes in inner and outer diameter;
  • production of high working accuracy tubes and tubes with high mechanical properties at the customer’s request;
  • prompt adoption of tubes with any diameter within 60 and 125 mm (by outer diameter).

Engineers of CJSC “IOMZ” developed innovative technology to produce tubes and this made possible not only to improve tubes quality but also to exclude harmful working conditions: no etching treatment, no drawing operations with use of lubricants necessary to utilize.
