Ventilation pipe for ventilation of the gas space of tanks without a pontoon and communication with the atmosphere. It is equipped with a fire barrier cassette and a protective hood.
The ventilation pipe ensures the communication of the gas space of the tank with the atmosphere and its ventilation, preventing the formation of overpressure and vacuum in tanks operated without overpressure. A fire barrier cassette is installed inside, which does not allow the flame to enter, and a protective hood against precipitation is installed on top.
It is available with a nominal bore DN 100-500. The body is made of steel with a protective and decorative coating; the fire barrier cassette is made of corrugated aluminum strips. It is mounted on the pipe of the tank roof through a flange.
