Corrosion of pneumatic butterfly valve and effective solutions
1. As we all know, metal corrosion has a considerable impact on the life, reliability and service life of pneumatic butterfly valves. The influence of mechanical and corrosion factors on metal greatly increases the total wear of contact surfaces.
2. Total wear on valve friction surface during operation. During valve operation, the friction surface is worn and damaged due to simultaneous mechanical action and chemical or electrochemical interaction between metal and environment.
3. For valves, the climatic conditions of their pipelines are complex; The presence of hydrogen sulfide, carbon dioxide and some organic acids in oil, natural gas and oil reservoir water will increase the destructive power of metal surface, thus rapidly losing the ability to work.
