Pressure Safety Vent

In atmospheric storage tanks with stable roof, where petroleum products are stored, pressure safety vents are useful in expulsing of the excess oxygene which appears during loading into tank to atmosphere in the most cost-efficient way. Since these vents minimize tank shrinkage and reduce economically air pollution, they are also useful for atmospheric ecological equilibrium. Pressure safety vents are generally manufactured between 2" and 12" in diameter. Body material is rust resisting aluminum cast which do not spark due to friction and hit and is resistant to petroleum products steam, which have ex-proof and spark proof characteristics.
