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.
