Using of non-destructive test of accoustic emission for prolonging the operation life of composite pressure cylinders

Abstract

Financial crisis in the years 2008 to 2013 had a negative effects also in a state administration, and as well in a purchase, renewing and services of technical means of fire protection. Under the terms of School educational and vocational establishment of the Fire and Rescue Service of the Czech republic (FRS CR), center in Frydek - Mistek, this condition was fully displayed at the FRS CR at the state of composite pressure cylinders (PCs), that are from the point of view of operation of the breathing apparatuses, and other technical means such as bags, sealing means, means for works on water, that are inevitable for their operability. In this article prolongation of an operation life of PCs is described, on the basis of supplementary nondestructive acoustic emission testing (AT), that is a part of hydraulic pressure test. In conclusion it is written the state of PCs after the operation life having been prolonged and before their final decommissioning.
