Plate-bending equipment

Taking into account the requirements of integrated iron and steel works, NKMZ offers equipment for all existing schemes of gas and oil large diameter pipes manufacturing:

  • Skelping by means of plate-bending machine
  • Press forming technique
  • Sequential press bending process


In order to convey plate or pipe, we have designed and ready to supply all kinds of technological equipment, such as: plate pilers, roller tables, transfer cars, etc
Except skelping, technological process of pipes manufacturing includes following stages:

  • Edge milling
  • Submerged arc welding of inside and outside welds
  • Ultrasonic and radiographic tests
  • Pipe expanding
  • Chamfer machining
  • Hydrostatic pipe testing
  • Pipe control and storing


The entire technological process is monitored by means of automated process control system. We have gained the experience in designing, manufacturing and commissioning of a set of equipment for skelping, based on the process of forming a pipe billet using a plate-bending and post-bending machine.
