Acoustic emissions tests in LPG tanks

This test replaces hydraulic tests on LPG tanks to determine the suitability of the tank without having to empty it and, therefore, have to stop supplying the customers while the test is being performed.

This test can be performed on aerial and buried tanks, no matter the capacity, in which the fluid contained is a LPG – usually propane. Periodic tests must be performed every 15 years to check their condition.

The test consists on the removal of the liquid phase from the tank that is heated it in a vaporiser, and returned to the tank in gas phase. After this process, the pressure is increased in a controlled manner, while signals are collected by a series of sensors placed on the walls of the tank. This non-destructive method helps to anticipate future defects, detecting their existence before the regular use causes a rupture.
