Abstract

The most sensitive leak detection method for high pressure vessels is based on the use of a mass spectrometer leak detector. Our Q60U type universal quadrupole mass spectrometer was incorporated into the leak test system (type LD-60) designed for the testing of the axial compensators of steam pipings. During manufacture of these items it is possible to detect leak rates ranging from 10-9 mbar l s-1 and 10-7 mbar l s-1 with a response time of 5 min and 5 s, respectively, using a combined slow-fast samplingunit and He as the test gas. The leak detector is pumped by an air-cooled, automatically controlled diffusion pump system.
