The welded stainless steel pipe is made from stainless steel by electric welding or sheet metal strips by means of forming and welding. Electrically welded tube is made of thermally without subsequent processing and hot-reducing.
Our Advantages:
1, Direct material sourcing from Bao Steel, ZPSS, TISCO.
2, More than 5 processing mills to produce the welded titanium tube for us. And also we own a steel tube mill.
3, Strong business cooperation with Bao Steel and Shanghai Minmetals.
4, More than usd$50,000,000 annual turnover.
