How to prevent corrosion of instrument valve
The anti-corrosion of instrument valve is mainly due to the correct selection of materials. Although the data of anti-corrosion is very rich, it is not easy to choose the right one, because the problem of corrosion is very complicated. The difficulty of selecting valve body material lies in not only the corrosion problem, but also the pressure and temperature resistance and long service life, which can greatly avoid leakage. Concept: the instrument pipe joint is an important part of the instrument measuring pipeline system. It can be used to press the nut and ferrule onto the pipe. Instrument valve is a kind of advanced connection valve in power station, oil refining, chemical plant and instrument pipeline. Whether it is reasonable economically and whether it is easy to buy. The second is to adopt lining measures, such as lead lining, aluminum lining, engineering plastics lining, natural rubber lining and various synthetic rubber lining. If the medium conditions permit, this is a saving method. Thirdly, in the case of low pressure and temperature, using non-metal as the main material of valve can often effectively prevent corrosion.
