EN10217-7 SUS 304 316 Austenitic Welded Tube Stainless Steel Seamless Pipe
"The pursuit of quality is our persistence"
We chose austenitic stainless steels from BAOSTEEL or TISCO as raw materials. Because these raw materials have high-quality properties, the effects after surface treatment will be more diversified. Pickling, polishing, mirror polishing, satin brushing, powder coating, you can choose the effect you want according to actual needs, we will try our best to help you complete.
"Stainless steel sanitary pipes with a outer diameter of 25.40mm to 101.6mm meters can meet 80% of the market requirements"
The outer diameter range of the stainless steel food grade tubes that our company has currently made is 15.88 mm to 2000 mm, if you need a bigger one, we can also complete it.
"The products we do the most are round pipes , rectangular pipes and square pipes. In this respect, our production line and workmanship are very mature."
If you need a profiled tube, please consult us with detail profile tube drawing pictures
