High temperature ball valve test requirements

     We know that high-temperature ball valves are mainly valves that operate in some high-temperature and harsh environments, such as in the coal chemical industry. Therefore, if the valve fails, it is likely to cause the system to stop or cause environmental pollution, and the serious ones can threaten the life. Safety issues, therefore, in order to ensure that the high-temperature ball valve will not have problems during operation, its testing is particularly important.

     High temperature ball valve test requirements

     Product testing can not only predict and analyze the problems that occur in the use of the valve, but also improve the development progress of the valve, reduce the trouble of online maintenance, disassembly and replacement of the valve, and avoid economic losses in the use of customers.

     Take the S-ZROB continuous reforming device valve in the petroleum refining process as an example to analyze the high temperature test process of the ball valve. The S-ZROB continuous reforming unit mainly realizes oil purification. The working conditions of the reforming catalyst station are very bad, the operating pressure is 4.26MPa, the operating temperature is 427℃, the circulating medium is high-hardness adsorbent, and the operating frequency is 3 times. /h. The valve is used at a high temperature and has strict requirements on sealing and action accuracy. Whether it can meet customer requirements in a high temperature environment requires sufficient theoretical and experimental data verification and support.

     The high-temperature ball valve test needs to complete data collection of valve sealing performance and operating conditions at high temperatures with increasing temperature. The ball valve should have a fault-free operating life of 200,000 times, and the sealing performance should meet the requirements of ANSIFCI/70-2VI for a long time.
