SS304 / SS316L stainless steel pipe flameproof cap / fireproof cap
Explosion-proof and fire-resistant ventilating caps are essential safety accessories for petroleum products during storage, and are widely used for gas venting during the storage and operation of petroleum products. The filter element of this product is composed of stainless steel cold sheet pressed uniform ripple. Corrosion resistance, can meet the needs of oil storage and ventilation. The breathable cap element is designed as a whole free-standing, one-time curing to ensure the stable size of the corrugations and easy to clean and accompany.

Fire-resistant breathable cap (breathable cap for short) is an important supporting equipment to ensure the safety of ventilation of gas stations and oil tanks. There are two types of connection for breathable caps: flange connection and thread connection. Flame arresters are also called flame filters, flame catchers and fire arresters. It is divided into two types, flame-retardant and detonation-proof. It is a triangular unit formed by an explosion-proof and fire-resistant corrugated metal core to destroy the flame. It is a safety device used to prevent the spread of flames of gases and liquids and to prevent flashbacks from causing explosions. It is usually installed in storage tanks and pipelines that transport or discharge flammable and explosive gases. Such as torches, heating combustion systems, petroleum gas recovery systems or other systems. SS304 / SS316L stainless steel pipe flameproof cap / fireproof cap
The top cap of the fire-resistant breathable cap is made of refractory aluminum plate, and the shell is cast aluminum. There are two kinds of stainless steel corrugated plate and aluminum corrugated plate, which meet the technical requirements of CB-5908-2005. When the fuel tank material expands or enters the oil, it is vented to the outside through the flame-resistant corrugated plate. When the oil tank is filled with oil, the air is sucked into the tank, and all fire sources are prevented and prevented from passing through to ensure the safety of the tank.

The vent cap should be installed vertically on the top of the oil tank to ensure the pressure balance inside and outside the tank. So as to ensure the safety of the tank and the gas station.
The breathability of the fire-resistant corrugated board of the breathable cap should be checked frequently to ensure good fire-resistant and breathable performance. During maintenance, unscrew the cap of the ventilating cap, and loosen the screw that fixes the fire wick, remove the fire wick, and check whether the fire wick is blocked, deformed or rusted. The fire wick should be cleaned or replaced immediately. Check twice a month. Times.
