What is the distance between the location of the breather valve on the tank vent line and the tank outlet?
Thread Content
The vent line of an atmospheric storage tank is quite long; can a breather valve be installed at the end of this vent line? Are there any specific requirements regarding the distance between the breather valve and the storage tank?
No, the breathing valve is installed on the storage tank, while a flame arrester is installed on the vent line
A breathing valve is an important accessory for ensuring the safety of oil tanks; it is installed on the top of the tank and consists of a pressure valve and a vacuum valve. Its function is, under normal circumstances, to maintain the integrity of the oil tank and to reduce oil evaporation losses to a certain extent. And when necessary, it can automatically ventilate to regulate the pressure inside and outside the oil tank, thereby ensuring its safety.
The breather valve must, in theory, be installed directly on the storage tank
No, you won’t be able to react in time, and your storage tank will explode
