1 1/4"

The minimum vent pipe size for an oil storage tank is 1 1/4 inches. This size is established to ensure proper ventilation of the tank, allowing for the expansion and contraction of air and preventing the formation of vacuum conditions that could lead to tank deformation or failure. Adequate venting is crucial for the safe operation of oil storage tanks, as it helps to maintain atmospheric pressure and prevents the accumulation of flammable vapors.

A vent pipe that is too small may not effectively support the necessary air exchange, which could increase the risk of pressure buildup and potential spills or leaks. Therefore, the standard of 1 1/4 inches has been put in place as a minimum to promote safety and efficiency in oil storage practices.
