русскийWhat are the anti-corrosion measures in the manufacturing and design process of copper valve manufacturers?
1. Valve material selection is an important factor in preventing valve corrosion. Generally, cast steel valves are usually used for water, oil and gas. If there are corrosive media such as acid and alkali, stainless steel is selected. Generally, stainless steel with a temperature below 200 degrees is used to make a passivation film in the medium to prevent further corrosion. The temperature of the highly corrosive medium is also high, so choose the super anti-corrosion alloy material. The medium is reducing, and the stainless steel material is selected, and the medium is oxidizing, and the stainless steel material is selected.
2. Surface coating Paint coating the surface of the valve is also a common anti-corrosion method. The elastic valve seat of the copper valve and the surface of the sealing gate valve are sprayed with epoxy paint.
3. Use lining material to separate the medium from the flow channel of the valve body. The lining material includes lining engineering plastics, lining natural rubber and various synthetic rubbers, etc. Generally, copper valves can only be used under low pressure and low working temperature. .
