SCZ50-A flame retardant ventilation cap, also known as SCZ50-A flame retardant ventilation cap, is installed at the end of oil tanks, storage tanks, and combustible gas emission systems. It is mainly used for fire prevention, waterproofing, dust prevention, and also plays a role in suction and exhaust during loading and unloading. When the oil tank material vaporizes or enters the oil tank, it is discharged outward through the flame retardant core corrugated plate. When unloading oil from the inside and outside of the oil tank, it can also suck air into the tank and prevent external sources of fire from entering, ensuring the fire safety of the oil tank.

The flame retardant vent cap is vertically installed on the top exhaust pipe of oil tanks and storage tanks. The breathability of the flame retardant corrugated plate of the flame retardant vent cap should be checked regularly to ensure good flame retardant and breathability performance. If impurities are found to block, deform or rust the flame retardant corrugated core plate, the flame retardant core should be cleaned or replaced immediately.

The flame arrester vent cap of Shanghai Yonglong Valve Factory meets the technical requirements of flame arresters for petroleum tanks CB-5908-2005, with a high-quality aluminum alloy molded shell, a 41mm high stainless steel corrugated flame arrester element, and a 304 stainless steel rainproof and dustproof cap. According to the flame arrester test procedure: 6) Explosion resistance test (7.6), 7) Burn resistance test (7.7) for testing. Explosion proof test: A mixture of propane and air was used for the test, with a propane concentration of 4.3% (error ± 5%). The test results showed that the explosion proof test was conducted continuously for 13 times, and each time it was able to extinguish the fire. Flame resistance test: A mixture of propane and air is used for the test, and the test results show that it can withstand continuous burning for more than 1 hour without tempering.
