Is it necessary to install a safety valve on pipelines for flammable liquids whose operating temperature can exceed the boiling point, between two isolation valves? What if the pipes are insulated? For flammable liquids such as dichloromethane and petroleum ether.
Please consider the semantic conditions that cause the temperature rise; addressing these conditions is better than installing a safety valve in this location. The function of a safety valve is to automatically release pressure in case of overpressure; it cannot ensure cooling through pressure release. For reference.
