Oil and gas exploration, refining and petrochemical processing applications for erosion resistance cermet lining

摘要

Production and gas exploration and oil that are exposed to the solid particulate erosion at a temperature of 1000 ℃ below, the present invention relates to a method of protecting a metal surface in the petrochemical process applications as well as the refinery. This method comprises the steps of providing an insert or heat erodible cermet lining to the metal surface in such applications, the ceramic phase of about 95 vol% a) from about 30, insert or cermet lining and b) metal binder phase and wherein the insert or cermet lining including the step of having a fracture toughness _{K 1C} of about 7.0MPa ^{· m 1/2} at least HEAT and erosion resistance index of at least 5.0. The metal surface may be provided with a heat-erodible cermet coating with HEAT erosion resistance index of at least 5.0. The advantages provided by this method, in particular, as well as outstanding thermal expansion compatibility to the base metal of the process equipment, high-temperature erosion resistance and corrosion resistance include poles in combination with outstanding fracture toughness. Guide process piping process vessel, and transfer lines, heat exchanger, cyclone, and sliding gate valve, feed nozzle, aeration nozzle, thermowell, valve body, internal riser, deflection shield, sand screen, as well as the method, oil sands mining It is used for a particular application to protect the equipment.
