ANALYSIS OF LEAK DETECTION SYSTEM FOR CRYO-INSULATION PRESSURE VESSELS

Leakage is one of main technical parameter for cryo-insulation pressure vessels.Measuring leak rate accurately is an important method to assess property,reliability and safety of products.In this paper,impacts of auxiliary pump,analysis of effective minimum detectable leak rate,leak detector,standard leak position and tracer gas response time for the cryo-insulation pressure vessels are discussed and analyzed.
