9+ Reasons: What Causes Tank Pressure Increase During Leak Test?

During a leak test, a sealed tank is pressurized to a specified level to assess its integrity. A pressure rise within the tank, contrary to the expected pressure decay in the presence of a leak, signifies an introduction of energy into the system. This typically stems from a change in the thermodynamic state of the gas contained within, or the introduction of additional gas mass. Sources include temperature fluctuations, which cause expansion of the gas, or vaporization of residual liquids within the tank, which adds gaseous mass to the system. For instance, if a tank is exposed to sunlight during a leak test, the resultant temperature increase of the gas inside leads to a corresponding rise in pressure.

Maintaining consistent and accurate leak testing procedures is crucial across diverse industries, from aerospace and automotive to manufacturing and chemical processing.
