Pipe Mill with ZTF Forming Process
ZTF forming is a pipe production process specially developed by Zhongtai Group. The process is designed to minimize the time it takes to complete round pipe production, lowering your operating costs. A tube production line using the ZTF forming process does not require the changing of any rollers in the breakdown section, lowering roll costs by about 60%.
- uring pipe and tube production, you do not need to change any molds in the breakdown section, leading to a 60% reduction in roll costs.
- It allows for the production of pipes with a variety of diameters through simple adjustment.
- Reduction in manpower
- Suitable X70 and N80 grade steel strips.
- The friction between the steel strip and rollers is reduced, extending the useful lifetime of the rollers.
- Rollers are easy to adjust.
ERW carbon steel pipe mills with our ZTF forming technology can produce pipes in a wide OD range from 48mm to 720mm and max. wall thickness up to 22mm.
