In recent years, with the rapid development of China's petrochemical industry, China's self-made and introduced large complete sets of equipment items increased, and its matching valve demand increased sharply. Valves are the main components in industrial pipelines. Whether it's good or bad and whether the choices are reasonable. It is very important for the safe and economical operation of the industrial piping system. Due to the pipeline of the mind is different. The functions of various valves are not the same, so there are many kinds of valves.
Erosion corrosion wear is the metal damage phenomenon caused by the high speed relative movement between the metal surface and the corrosive fluid. It is the result of the interaction of erosion corrosion and wear of materials. The metal parts in contact with corrosive medium bear serious erosion corrosion wear of liquid-solid two-phase flow, which leads to the failure of parts or scrap of equipment. We usually use the domestic valve in use process may be long in the acid, alkali, salt and sediment state of medium or high temperature corrosion, withstand strong corrosion and scouring, at the same time there are density than the pressure under the action of the seal between the friction and wear, its are harsh working environment, causing the untight seal leakage flow, the leakage flow serious when, in turn, increase wear and tear, It creates a vicious cycle where wear and leakage negatively affect each other. In this erosion and corrosion interaction under the conditions of work, the existing domestic wear-resistant valve life is low, poor sealing, resulting in frequent replacement, domestic valve life is generally 3-6 months, which will cause great losses to the factory production. This not only wastes a lot of manpower and material resources, but also causes greater economic losses in the process of replacement shutdown. Therefore, more often in the key parts we have to use imported wear-resisting valves, although the life of imported wear-resisting valves is generally only 2-3 times that of domestic wear-resisting valves, but the price is much higher than that of domestic wear-resisting valves.
Our company and foreign enterprises all the year round to maintain the valve technology communication and exchange, so in the wear-resistant valve spraying wear-resistant corrosion technology has a mature technical solution, can help customers to achieve mass processing of various wear-resistant valve of all kinds of long-life coating.
