Petrochemical industry

1.Industry Background Introduction

Petrochemical equipment often operates in environments containing various corrosive media such as CO2, H2S, Cl, etc., with high temperature and pressure underground and harsh working conditions. As a result, corrosion perforation and failure accidents caused by wear and tear occur frequently, seriously affecting oilfield production. The traditional surface treatment of components mainly adopts technologies such as carbon nitrogen co diffusion, martensitic strengthening, high chromium wear-resistant treatment, ion nitriding, etc., which have problems such as high energy consumption, low process level, high pollution, difficult repair, and high cost. Laser cladding technology can effectively solve these problems, significantly improving the physical and chemical properties of mechanical components such as wear resistance, corrosion resistance, heat resistance, and oxidation resistance.
