  • Leak detection methods and defining the sizes of leaks
    Pregelj, Andrej ; Drab, Marjan ; Mozetič, Miran, 1961-
    There is a constantly growing need for products and technologies that for their realisation requirre hermetically closed elements, vessels and tubes. Envelopes with greater or smaller vacuum ... tightness had to assure a satisfactory isolation between external atmosphere and inside over-or under pressure. Crytical leak spots in closed systems are usually: connections, gaskets, welded and brazed joints, defects in material etc. Regarding to quality demands in different production processes, technical people very often encounter with standards for tightness testing. Wishing to state if an element or system meets with corresponding standards we have to be familiar with the procedures enabling the following appointments: - question if there is leakingor not, - settlement of the leak size, - detection of leak locality. For solving the mentioned problems different treatments and techniques are known but among them there is no an universal method. Each testing is suitable only for a selected leak rate or for fixed forms and technologies. Oura rticle presents the leak types, their sizes and various leak detection techniques.
