The air permeability of the flame retardant corrugated plate of the breathable cap should be checked frequently to ensure good flame retardant and air permeability properties. When maintaining, unscrew the upper cover of the breathable cap and loosen the screws securing the fire-resistant core. Remove the fire-resistant core and check whether the fire-resistant core is clogged, deformed or rusted. be cleaned or replaced immediately and checked twice a month.
What is the purpose of the breather plug in water supply and drainage?
There are some differences between the two, but they are both devices security.
The flame arrester is generally installed in the pipeline carrying combustible gas, or on the ventilated tank. It is a device that prevents the propagation of the flame (deflagration or detonation). It consists of a flame-arresting core, a flame-arresting shell and accessories.
The flame retardant vent cap is a safety device used to prevent the hydrogen flame from spreading outward. It is made of a solid material (fireproof element) with many small channels or spaces that can allow gas to pass through. The gap or channel of the flame retardant element should be as small as possible, so that when the flame enters the flame arrester, the flame retardant element is divided into several small flame streams due to heat transfer ( the gas is cooled). ) and the wall effect, the flame flow is extinguished.

Prevent external flames from entering equipment and pipelines containing flammable and explosive gases or prevent flames from spreading between equipment and pipelines. The flame arrester is designed and manufactured based on the principle that when the flame passes through the narrow pores of the thermal conductor, it goes out due to heat loss.
Detailed information
The top cap of the explosion-proof and flame-retardant vent cap is made of flame-retardant stainless steel plate sprayed with plastic. , and the hull is made of cast aluminum. The fireproof core has stainless steel corrugated plates, which meet the technical requirements of SY/T0511-96. When the tank material expands or oil enters, it will be released.evacuated through the fireproof core corrugated plate.
When the oil is discharged from the tank, air is drawn into the tank and all fire sources cannot pass through to ensure safety. The air permeability of the fireproof corrugated sheet metal of the ventilation hood should be checked regularly to ensure good fireproofing and air permeability performance.
