Applications:
We,this type seamless and welded food steel tube be widely in food production all over the world
In passed many years,the factories be warmly welcome to use food bright surface both inside and outside stainless steel tubeing,in order to reach high quality from European,Japanese and others countries,we owned a set of advanced equirpment for material chemical component test,physical performance test and hydraulic test etc.
Our advantage
- Bright Annealing
- Strict tolerance control
- Good quality control system
- Good after sales services
- Good package
