Product Details

Stainless Steel Pipe Advantages

Stainless steel pipe is a kind of hollow round steel strip, which is widely used in industrial pipelines and mechanical structural parts of petroleum, chemical, medical, food, light industry, machinery and instrumentation. In addition, it is light in weight when the bending and torsional strengths are the same, so it is also widely used in the manufacture of mechanical parts and engineering structures. It can also be used as furniture and kitchenware.
Due to its overall corrosion resistance and good machinability, stainless steel tubing is used in a wide variety of industries/markets. Tubing is often considered a conduit for liquids and is measured by internal diameter or ID.
Some examples of industries include marine, chemical and petrochemical, oil and gas, and renewable energy.
Upon special request, we can customize your stainless steel tubing to your size and quantity.
