Shanghai flame retardant breathable cap

Shanghai fire-resistant breathable cap is an important supporting equipment to ensure the breathability and vacuum safety of gas stations, industrial oil tanks, etc. The connection forms of breathable cap include flange connection and threaded connection. It should be installed vertically at the top of the oil tank to ensure the balance of pressure inside and outside the tank, thereby ensuring the safety of the tank body and gas station.

Fire resistant breathable cap is an important supporting equipment to ensure the breathability and vacuum safety of gas stations, industrial oil tanks, etc. The connection forms of breathable cap include flange connection and threaded connection.

　　Shanghai flame retardant breathable capProduct Features

The top cap of the fire-resistant breathable cap is made of Cr18Ni9Ti, and the shell is made of cast aluminum. Fireproof ring material: Stainless steel SS304 corrugated plate. When the oil tank material expands or oil enters, it is vented outward through the flame retardant layer. When oil is discharged from the tank, it is sucked into the tank and all sources of ignition are prevented and eliminated from passing through, ensuring the safety of the tank.

Installation precautions:

The breathable cap should be installed vertically at the top of the oil tank to ensure the balance of pressure inside and outside the tank. To ensure the safety of tanks and gas stations.

Repair and maintenance:

The breathability of the flame retardant ring of the breathable cap should be checked regularly to ensure good flame retardant and breathability performance. During maintenance, unscrew the screws on the top cover of the breathable cap and loosen the screws that fix the flame retardant core. Remove the flame retardant core and check whether the flame retardant ring is blocked or deformed by dust. The flame arrester should be cleaned or replaced immediately, and checked every three months.
