To satisfy needs of the steel-making plant, NKMZ may offer the equipment for producing large dia, gas and oil tubes through the use of any applicable technologies and processes given below:

Tube billet forming on a sheet bending machine;
Press forming technique;
Sequential press bending process.

To convey the sheet or tube, NKMZ is capable to manufacture and supply all kinds of the related process equipment such as sheet pilers, roller tables, transfer cars, etc.

Edge milling;
Carbon-dioxide-shielded are welding of the preliminary welds;
Submerged are welding of the inside and outside welds;
Ultrasonic and radiographic tests;
Tube expanding;
Chamfer machining;
Hydrostatic tube testing;
Tube checking and storing.

The entire tube making is monitored through the aid of the automatic process control system.
We have gained an experience in designing, producing and commissioning of the tube billet forming facilities through the use of the sheet bending and rebinding machines.
