I. Improvement of Corrosion Resistance Resistance to Medium Corrosion: In various operating environments, valves are exposed to different media such as acids, alkalis, salt solutions, and corrosive gases. These media may corrode the metal surface of the valve, thereby reducing its service life. Electroplating a layer of corrosion-resistant metal or alloy—such as chromium, nickel, or zinc&mda...

A gate valve is widely used for full open or full close flow control in pipeline systems. If a gate valve goes bad, then problems such as leakage, jamming, or operating failure will occur, directly affecting system safety and efficiency. Most gate valve failures develop gradually. If routine maintenance is ignored, then failure risk will increase significantly. Sealing Failure If the...

In seawater piping systems, globe valves can be used to control and isolate fluid flow, provided that the materials and corrosion protection design are suitable for seawater service conditions. Seawater contains a high concentration of chloride ions and dissolved oxygen. If the valve material is not properly selected, corrosion can occur rapidly. Therefore, when globe valves are used in sea...
