Pipeline heat-dissipating venting flame arresting are usually installed in tanks and pipelines that transport or discharge flammable and explosive gases. They are used to prevent flammable gases, liquid flames and prevent tempering and cause explosions. Can be used in flares, heating combustion systems, petroleum gas recovery systems or other flammable gas systems.
