Stainless Steel
Stainless steel is a widely used material, applied in the production equipment and components with high requirement for the comprehensive performance of corrosion resistance and molding. In order to maintain the inherent corrosion resistance of stainless steel, stainless steel tubes must contain more than 18% chromium and 8% nickel.

6 Inch Stainless Steel Pipe ASTM A358 A790 Round Hollow Steel Tube

Stainless steel pipe

Stainless steel pipe is a kind of hollow and long steel pipe, which is widely used in petroleum, chemical, medical, food, light
industry, mechanical instrument and so on. In In addition, in the same bending and torsional strength, stainless steel pipe has light weight, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used for furniture, kitchenware, etc.

Notice:Our tubes are welded by High frequency resistance welding, submerged arc welding, TIG welding and GMAW welding methods. Our pipes can get fully welded and smooth inner welding, without blisters, leak welding or black line. All of our pipes are good for bending.

Our pipes

Produced with brand-new normal material coil as raw material, with high purity, especially the main elements such as nickel, chromium and copper are up to standard and stable.

The pipes from other small factories

In order to reduce cost, many manufacturers use slag turning materials with Low purity, unstable composition and easy to rust.

Our Pipes

The surface is smooth without peeling, black spots, cracks and pulling.There is no sand hole and the weld is flat.

The pipes from other small factories

The surface is dull peeling, sand holes, black spots, cracks, strain and uneven welding.

Application
