The core components of flat gate valves used in petrochemical industry require high pressure, wear resistance, H2S and CO2 corrosion resistance, especially wellhead Christmas tree valves. Our company selects high-quality thermal spraying powder as raw material, adopts supersonic spraying equipment, optimizes thermal spraying technology, and supports advanced processing equipment and processing technology, so that the coating compactness can meet the requirements of air sealing under 140MPa, the coating porosity is less than 1%, the bonding strength exceeds 75MPa, the hardness can reach HV1500 and the fluctuation of hardness uniformity does not exceed HV100;; After coating processing, the surface of the product can reach mirror surface, the roughness is lower than Ra0.1, and the flatness does not exceed 2 light bands, which can effectively reduce the friction coefficient between valve plate and valve seat and prolong its service life.
