What is the reason for the leakage of the carbon steel gate valve.

carbon steel gate valve is an industrial valve, in petroleum, chemical, power station and other industries are widely usedWith automation, easy operation, long service life and other advantages, but in the process of use due to their own or external factors, carbon steel gate valve will leakSo, what is the cause of the carbon valve leakage? There are a number of common reasonscarbon steel gate valvecarbon steel gate valve leakage reason
1, wedge seal ring processing accuracy low caused carbon steel gate valve leakage, as long as the choice of large brand of gate valve, then the general quality of spare parts are better, so that there will be no seal ring processing accuracy of low circumstances2, the production operation conditions are unstable leading to leakage inside the gate valve, the gate valve on the working environment requirements are relatively high, if the pressure and temperature environment is unstable, the magnitude of change is too large, then the seal ring to bear the impact pressure, so it is easy to deform the situation, in the end will lead to valve leakage3, valve maintenance quality is poor resulting in leakage inside the valve, some staff in the maintenance valve, did not clean the sealing ring sealing surface clean, the presence of impurities affect the operation of the valve, long before will scratch the sealing surface, which will lead to valve leakage4, the media corrosion wedge seal ring caused by the valve leakage, valve long-term operation, under the influence of the medium, the seal ring is easy to be corroded, corrosion to a certain extent, the seal ring is damaged, so that the gate valve leakage situation5, the valve body is defective, if the valve body if there are pores, slag, cracks, sand eye and other problems, then the use of the valve is prone to leakagecarbon steel gate valvein short, carbon steel gate valve leakage is a more common problem, if there is a leak, then it will endanger the safety of equipment and staff, so to find out the cause and solve the problem in a timely mannerCarbon steel valves are not resistant to corrosion, can only be used in steam, oil, water and other non-corrosive media pipes, and carbon steel valves cost is much lower than stainless steel costs, so generally no corrosive steam and other pipes are using carbon steel, and corrosive are using stainless steel valves and other materials.
