Tubos redondos de acero inoxidable de alta calidad 316L con prueba hidráulica

"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 welded 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 welding 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.

"One-stop shopping, reducing the procurement process."
We have extensive experience in providing stainless steel welding pipes and fittings for more than 118 project contractors and stockists. 

We has a complete series of advanced equipment from Germany, Japan, Italy and France, including plasma auto-welding machine, polishing facility, online inner bead removed and online bright anneal facilities etc.

The tubes, produced by our facilities, are mainly applied for mechanical industries in boiler, heat exchanger, condenser, heater. After inner and outer polished, tubes are widely used in sanitary industries of food, beverage, biology, pharmacy, beer and electron. Large diameter fluid conveying welded pipes, ranging 325-2000 mm, are commonly used in oil, chemical.

We have three factories that can be used to make stainless steel pipes. You don't have to worry about the production cycle at all.We will formulate a production plan according to the delivery time to ensure that it can be completed on time.

We have a team of professional designers, engineers and skillful welders.We can make products that meet your requirements.
