LEAK TEST STANDS
Hydrogen Leak Testing Stands for Composite Pressure Vessels
Test Stand Features:
• For vessels up to 600L with test pressure up to 12,600 psi
• Cycle times of 5-30min. (depending on vessel volume)
• Fully automatic with transport system for vessel
• Accumulation or vacuum test chambers
• Nitrogen-Helium-Mix or Nitrogen-Hydrogen-Mix test gases
• Includes flushing and OTV functional test
Our leak test stands serve as the functional test for the production of hydrogen composite pressure vessels.
National and international regulations as well as customer specifications mandate end-of-line leak testing to ensure performance and safety of every vessel. The leak test is performed with a tracer gas which allows fast and accurate integral testing in a vacuum or accumulation chamber. During testing, the vessels can be safely pressurized and the tracer gas is recovered during depressurization.
The Hydrogen Leak Test Stand is available in 3 sizes to fit all commonly produced vessel sizes.
Based on the vessel dimensions and later application, customers can configure the proven modular design in the sizes S, M or L. The chart below shows the delimitations between these 3 different sizes.
