The maintenance of the tank flame arrester can achieve these points, and it can be used for a long time.
Storage tank flame arrester is the introduction of foreign advanced technology, accompanied by advanced processing equipment and perfect detection device, the production of explosion-proof corrugated flame arrester, has a compact structure, high reliability, fire resistance core parts explosion-proof, anti-corrosion, fire resistance performance , Easy to clean and so on. We know that the flame arrester is composed of many small channels or pores. When the flame enters these small channels, many small flame streams are formed. Due to the large heat transfer area of the channels or pores, after the flames exchange heat through the channel walls, the temperature drops and the flames are extinguished to a certain extent. The tests performed showed that when the thermal conductivity of the flame arrester material was increased by 460 times, its quenching diameter changed by only 2.6%. This shows that material issues are secondary. That is, heat transfer is a cause of extinguishing the flame, but it is not the main reason.
The function of the tank flame arrester is to allow flammable and explosive gases to pass through, and to prevent suffocation of the flame. Suitable flame retardant gases include: oxygen, hydrogen, natural gas, and biogas. It is also used to install important safety equipment on fixed-top storage tanks such as crude oil, gasoline, kerosene, diesel, aromatics, and sulfur. Storage tank flame arrester is suitable for combustible gas pipelines, such as gasoline, kerosene, light diesel oil, stupid oil, petrol, crude oil and other oil storage or torch systems, gas purification systems, gas analysis systems, coal mine gas emission systems, heating furnace Fuel gas pipelines can also be used in acetylene, oxygen, nitrogen, and natural gas pipeline supplies. This valve can be used together with breathing valve or alone.
Maintenance method of storage tank flame arrester:
1. In order to ensure the full performance of the flame arrester, you must carefully read the instructions provided by the manufacturer before installing the flame arrester.
2. When reinstalling the flame arrester, the gasket should be renewed and the sealing surface should be clean and free of damage, and no air leakage should be allowed.
3. The blocked fire arrester should be cleaned to ensure that each eyelet is unobstructed. The deformed or corroded fire arrestor should be replaced.
4. When cleaning the core parts, high-pressure steam, non-corrosive solvents or compressed air should be used for cleaning. Sharp objects should not be used for scrubbing.
5. It should be checked every six months. Inspect the tank flame arrester for problems such as blockage, deformation, or corrosion.
