Valve Fire Testing

The petrochemical industry is one of the pillars industries of the national economy, its production processes are complex and most of the raw materials, semi-finished and finished products used in the production process are flammable and explosive substances, which can easily cause fires and explosions. Due to the potential fire hazard the valves used on some occasions must be specially designed so that we have high sealing and operating performance even after being in contact with high temperatures for long periods of time. To measure the fire resistance of the valves of a specific test: fire resistance test. There are many standards to follow when testing valves for fire resistance, both in China and around the world, and testing methods and standards of judgment also change. Therefore, learning each standard is of great importance to understand the test requirements and improve the fire resistance performance of the valves.

 Fire resistance test of JB / T 6899 valves

ISO10497 specifies the fire test requirements for valves and fire test methods for valves to verify the pressure resistance performance of valves during and after fire tests. This standard does not include manual transmissions or similar parts of machinery from the valve assembly. The fire resistance test requirements of the transmission device and other types of valve transmission devices (such as electric, pneumatic or hydraulic), require special protection to ensure that the valve can be operated under the conditions established in the test.

The valve fire test can be dangerous, so personal safety is an essential factor to consider. Due to the structure of the test valve, the test equipment and the fire resistance test, the pressure interface can break dangerously. Therefore, in order to ensure personal safety, adequate protective devices must be installed around the test chamber and other necessary measures must be taken.
