What is the maximum allowable test pressure on any oil tank connected to the piping?

The maximum allowable test pressure on any oil tank connected to the piping is established to ensure safety and integrity in the system's design and operation. A test pressure of 10 psig is typically recognized as a standard limit in the industry for hydrostatic pressure testing of oil tanks.

This pressure is sufficient to reveal any leaks or weaknesses in the tank without putting undue stress on the tank material or creating a risk of rupture during the test. The selection of this specific limit balances safety with practical considerations, ensuring that the tanks can function effectively under normal operating conditions. Exceeding this pressure could risk damaging the tank or connections, leading to safety hazards or costly repairs.

Establishing test pressures at this level helps ensure compliance with regulations and industry best practices, helping to maintain a safe environment for both personnel and equipment.
