VALVE GATE COATING INTRODUCTION

VALVE GATE COATING INTRODUCTION tungsten carbide valve gate 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. Since there is an urgent need to improve wear resistance and corrosion resistance of mining and processing equipment in petroleum and petrochemical industries, surface engineering
