Material

The most common materials used are carbon steel, alloy steel and stainless steel. Carbon steel is used a lot in industry because it is cheap. It can also be coated to protect it from rust. Stainless steel is expensive, but it lasts a long time and is resistant to rust. Alloy steel is used less than carbon and stainless steel, but it works well and costs a lot.

Application

They are mainly used in the petroleum, chemical industry, power plants, water management, aerospace, military industry, metallurgy, shipbuilding, gas, etc.
