The materials of steel pipes mainly include carbon steel, alloy steel, stainless steel, aluminum alloy, etc. details as follows:

Carbon steel pipe. This is a common steel pipe material that includes steels with different carbon contents (low carbon steel, medium carbon steel, and high carbon steel). This type of steel pipe is usually used to transport fluids such as water and gas, and to make machine parts.

Alloy steel pipe. This kind of steel pipe is formed by adding a certain amount of alloy elements (such as chromium, molybdenum, nickel, titanium, etc.) on the basis of carbon steel. It has the properties of heat resistance, wear resistance and corrosion resistance, and is suitable for high temperature and high pressure. of pipes and valves.

Stainless steel pipe. This kind of steel pipe is an alloy product composed of iron, chromium, nickel and other metal elements. It has good corrosion resistance and is suitable for special environments such as strong acid and strong alkali.

Aluminum alloy steel pipe. This kind of steel pipe is made of aluminum alloy and has the characteristics of low density, high strength, good rigidity and strong corrosion resistance. It is widely used in aerospace, automobile manufacturing, construction and other fields.

In addition, steel pipes can also be divided into seamless steel pipes and welded steel pipes according to the production process. Seamless steel pipes are divided into hot-rolled and cold-rolled (drawn). Welded steel pipes are divided into straight seam welded steel pipes and spiral seam welded steel pipes.
