What size vent pipe is required for a waste oil tank?

The requirement for a 2-inch vent pipe for a waste oil tank is based on safety and functionality considerations. A larger vent pipe size, such as 2 inches, ensures that there is adequate airflow to prevent pressure buildup within the tank. In waste oil applications, it is critical to allow vapors to escape efficiently to avoid the risks of overpressure and potential tank failure.

Additionally, a vent pipe of this size accommodates the necessary ventilation needed during both filling and dispensing operations. Ensuring proper ventilation helps prevent the accumulation of harmful fumes, thereby enhancing safety for both the environment and individuals working with the oil storage system. This standardization in vent pipe sizing is often mandated by regulations and industry best practices to ensure all waste oil handling aligns with established safety protocols.
