Tungsten carbide valve gate FAQ FOR CLIENTS

Stainless steel valve gates

Valve Gate: The core parts of flat gate valves used in the petrochemical industry require high pressure, wear resistance, corrosion prevention against H2S and CO2, especially wellhead and Christmas tree valves have higher requirements.

PRODUCT PARAMETERS

Valve Gate: The core parts of flat gate valves used in the petrochemical industry require high pressure, wear resistance, corrosion prevention against H2S and CO2, especially wellhead and Christmas tree valves have higher requirements. Our company selects thermal spraying technology which using high-quality thermal spraying powder as raw material, adopts supersonic spraying equipment, optimizes thermal spraying process, and supports advanced processing equipment and technology, so that the denseness of coating can meet the gas sealing requirements under up to 140 MPa, the coating porosity <1%, the bonding strength exceeds 75MPa, the hardness reaches HV1500 and the hardness uniformity fluctuates by no more than HV100; the product surface after coating can reach mirror surface, with roughness less than Ra0.1, and flatness no more than 2 bands, which can effectively reduce the coefficient of friction between Valve Gate and valve seat and improve its service life.
