The petrochemical industry is one of the pillar industries of the national economy. Its production process is complex, and the raw materials, semi-finished products and finished products used in the production process are mostly inflammable and explosive substances, which are very likely to cause fire and explosion accidents.

Due to the potential danger of fires in some valves that are prone to fire, the valves used in these applications should be specially designed to provide a certain sealing performance and operational performance after a certain period of fire. Fire resistance testing is an important tool in measuring the fire resistance of valves. At present, there are many standards for valve fire test at home and abroad, and the test methods and judgment standards are not the same. Therefore, learning the various standards is of great significance for understanding the fire test requirements of the valve and improving the fire resistance of the valve.

Here are some international standards listed for your reference:

ISO10497 Valve Test - Fire Test Requirements for Valves.
API standards: Fire resistance test of API 607 to 1/4 week valve and non-metallic valve seat valve.
API 6FA Valve Fire Test Specification.
API 6FD Valve Fire Test Specification.
