ERW 12CrMo Alloy Steel Pipe
12CrMo alloy steel pipe can withstand temperatures up to 600°C, which is more than twice that of conventional steel pipes. This means that in high-temperature environments, this kind of steel pipe can remain stable and is not prone to deformation or failure.
Good corrosion resistance: Steel pipes can resist the erosion of corrosive media such as acids, alkalis, and salts, so they have good durability in corrosive environments.
Manufacturing process of 12CrMo welded steel pipe:
The raw material for manufacturing this steel pipe is high quality low alloy steel. Choosing the right raw materials is the key to ensuring the quality of steel pipes. Using hot rolling or cold rolling processes, steel pipe shapes and sizes that meet the requirements can be obtained. Through the use of heat treatment processes such as quenching and tempering, the structure and performance of the steel pipe can be optimized. Heat treatment can change the internal structure of steel, thereby changing its physical and mechanical properties. The surface finish and corrosion resistance of steel pipes can be improved by surface treatment processes such as pickling and sandblasting. These processes can remove impurities and oxide layers on the surface and increase the corrosion resistance of steel pipes.
These characteristics and processes make 12CrMo steel pipes widely used in many fields, such as petrochemical industry, electric power, and other fields that need to withstand high temperature, high pressure, and corrosive environments.
