Natural Gas gas is indispensable for the development of people and economic, it provides great convenience for us. So the natural gas pipeline and gas pipeline valve is increasing every year. So what is the different between gas pipeline valve and normal valve? Prime Steel Pipe will tell you next. Please note that Prime Steel Pipe is a excellent gas pipeline valve provider, we can provide whatever you need.
At first, gas pipeline valve should choose the material that can resist sulfur and corrosion. It is because gas pipeline need to transport the gas containing a lot of hydrogen sulfide (which is a toxic and corrosive gas, and iron will become iron sulfide by the reaction, flaky peeling and wear eclipse machinery and equipment).
Second, most of the natural gas pipeline network were built on the edge of the city, workers should to operate, maintain and inspect regularly. If the gas pipeline were built in complex areas, natural gas leaks may result in serious fire incidents. The pipeline is closer from the city, the valve for preventing the leakage is more important. The requirement of the gas pipeline valve is very strict, in order to ensure the sealing performance of the pipeline valves, valve with excellent corrosion resistance, wear resistance, self lubrication and flexibility.
Third, the working time of gas pipeline is longer than others, once operational, within a few years is not allowed to stop running. Pipeline transportation of natural gas facing the entire city a large number of users, residents, businesses, factories, does not be allowed a moment interrupted. In the pipeline, the pipeline valve failure could cause disastrous consequences. The mainline gas pipeline valve life requires more than 30 years.
Fourth, as the high pressure pipeline has a large caliber, the switching time is fast, gas pipeline valve should has high torque drive. The pipeline valves require that the force is small. Emergency shut-off valve must be capable of long-term in the fully open state, when necessary, quickly locking the pipe. Requirements of the location of valve opening and closing and opening indicator is accurate, easy to understand, to meet the appropriate switching speed.
