  • Baosteel Seamless Steel Pipe Concept
    Oct 29, 2018

    Baosteel seamless steel pipe is made of steel ingot or solid tube blank by perforation, and then made by hot rolling, cold rolling or cold drawing; high quality carbon structure used for steam boiler pipes mainly used to manufacture high pressure and above pressure. Steel, alloy structural steel and stainless steel heat-resistant steel seamless steel pipe. Baosteel seamless steel pipe plays an important role in China's steel pipe industry.

    Baosteel seamless steel pipe is mainly used for the manufacture of high-quality carbon structural steel, alloy structural steel and stainless steel heat-resistant steel seamless steel pipe for steam boiler pipes with high pressure and above. These boiler pipes are often operated under high temperature and high pressure. The 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 high pressure boiler tube is guaranteed to have chemical composition and machinery. In addition to performance, it is necessary to do the hydraulic test one by one, and to make the flaring and flattening test. The steel pipe is delivered in a heat treated state. In addition, there are certain requirements for the microstructure, grain size and decarburization layer of the finished steel pipe.
