Ceramic lined pipe

The late eighty`s, American technology of rare eath wear resistant steel was introduced into our country. The relevant experts researched and made many experiments. The rare-earth wear-resistant steel had occupied the main position.Rare-earth wear-resistant steel is based on 40 steel. Cr, Ni, Si, Mo, Mn, Re elements are mixed in 40 steel forming low alloy steel which carbon content is 0.35~ 0.45%. Experienced long-term production making and many failures, we summed up a reasonable science and new experience.A certain amount of rare earth element is added into steel can improve the quality of alloy steel and can fining grains also can form a protective film on surface. A certain amount of Mo is added, the alloy under certain temperature and certain antioxidant effect, increase the service life.A certain amount of boron carbide is added, hardness can be controlled in the range HRC45 ~ 65. At the same time solve the contradictions between the hardness and weldability of wear resistant ste...

High-chromium alloy elbow 22.5 degree is a high-strength low-alloy rare earth heat, wear and pipe fittings suitable for power plant coal boiler systems, powder feeding, ash slagging pipe. RE wear resistant alloy pipes well, give full play to the high chromium cast iron (KmTBCr28MoCuRe) wear resistance. Pressure is high. Applicable to any pressure level. Use in conjunction with the outer lining tight, using a special process to form a connection between the composite layer solution to ensure the reliability of operation, has good resistance to mechanical shock, thermal shock resistance, easy installation and connection, any cutting, welding. Steel – High-chromium-nickel alloy composite pipe complex by the outer wall and the inner liner is made of 5-12mm thick wall seamless steel pipe, lined 6-25mm thick high-chromium-nickel alloy, centrifugal composite made of straight pipe, pipe vacuum negative forged, the product takes full advantage of the large seamless steel pipe bearing capacity, ...
