Abstract

Apparatus for testing a number of pressure vessels (10) comprises an accumulator (11) to deliver fluid pressure via hydraulic hoses and a pressure gauge (12). Detectors (14) are mounted to the vessels to sense acoustic emission (AE) when the vessels are subjected to cyclical pressurisation and de-pressurisation. AE signals from the detectors are transmitted to a central processing unit (13) for analysis and display on a display unit (15). A prediction of the working lifespan of the vessels is made by analysing AE signals occurring when the pressure in the vessels is on the increase.
