The oil cracking pipe is mainly used for the manufacture of high-quality carbon structural steel, alloy structural steel and stainless steel heat-resistant steel high-pressure seamless pipes for steam boiler pipes such as high pressure and above. These boiler pipes work under high temperature and high pressure, and oil The cracking tube will also oxidize and corrode under the action of high temperature flue gas and water vapor. Therefore, the steel pipe is required to have high durability, high oxidation resistance and good structural stability.

The oil cracking tube is used for high-pressure, ultra-high pressure production of high-quality carbon structural steel, alloy structural steel and stainless steel high-pressure seamless pipe, mainly used for the production of high-pressure, high-pressure steam boiler tubes. These petroleum cracking tubes work under high temperature and high pressure, and the pipes will also oxidize and corrode under the action of high temperature flue gas and steam. Therefore, steel is required.

The tube has the advantages of high durability, good oxidation resistance and good structural stability. The quality of high-quality carbon structural steel is 20g, 20MnG, 25MnG, alloy structural steel 15Mo, 20Mo, 12CrMo, 15CrMo, 12Cr2Mo, 12CrMo, 12Cr3MVSiTiB, etc.; and anti-rust steel is usually used for 1Cr18Ni9, 1Cr18Ni11Nb high pressure.

In order to ensure the chemical composition and mechanical properties of the boiler, the boiler tubes should be hydraulically tested. They should be opened and flattened, and high pressure seamless tubes will be transported during heat treatment.
