In chemical or petrochemical production, petrochemical process pumps can work under high temperature, low temperature or ultra-low temperature, high pressure, flammable, explosive, toxic and strong corrosive media, and can also work under high inlet pressure, high lift, high viscosity, and small flow , Work under high cavitation conditions. The materials of petrochemical process pumps can be used according to the working conditions or user needs: carbon steel, stainless steel, heat-resistant, wear-resistant steel and other materials. The following is the corrosion resistance selection table of the flow components of petrochemical process pumps for reference:
The petrochemical process pump can transport media:
1. Inorganic and organic acids such as sulfuric acid, nitric acid, hydrochloric acid and phosphoric acid at various temperatures and concentrations.
2. Alkaline solutions such as sodium hydroxide and sodium carbonate at various temperatures and concentrations.
3. Various salt solutions.
4. Various liquid petrochemical products, organic compounds, and other corrosive raw materials and products.
Petrochemical process pumps are mainly used for:
1. Oil refinery, petrochemical industry, coal processing industry and low temperature engineering.
2. Process industry of oil refining and coal industry.
3. Chemical industry, papermaking and pulp industry.
4. Water supply plant and desalination plant.
5. Power plant.
6. Environmental protection projects.
7. Ships and offshore industries, etc.
