If you are still suffering from the inconvenience caused by the corrosion and cracking of the pipeline, or you are suffering from the failure to find a suitable stainless steel sanitary tube supplier. Please read the following content in 3 minutes. I hope it can be helpful for you.
Our stainless steel weld pipes and fittings are not only sold to domestic markets,but also exported to many countries like Australia,Canada,Germany,Holland,Russia,Saudi Arabia,Spain,the United Kingdom,the United States,UAE,etc.
"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 engineering drawings with parameters. Our engineers will analyze the technical difficulties and discuss cooperation plans with you.

1.The inner wall of the our pipeline is smooth and not easy to scale, so it is not easy to be infected by bacteria, reduce coliform bacteria poisoning and other hazards.And it ensures the safety of drinking. .
2.Stainless steel tube is 3 times stronger than steel pipe and 8-10 times stronger than plastic pipe, which is not easy to leak. Stainless steel pipes are also resistant to damage in earthquakes because they are impact resistant.
3.Stainless steel tubing has low thermal conductivity, the thermal insulation performance is five times that of copper pipe, so it is also suitable for application in high temperature fluid.
