Pressure Testing H2 Components
Our flagship H2 test bench is utilised in research & development. In addition, it is used for constant benchmarking of the manufacturing process to validate H2 component quality. The rig is qualified to test H2 components such as 0n-tank valves, sensors, hoses, fuel cell components and more.
R&D Pressure Pulsation Test Stand for H2 Components up to 2000 bar
P+P test stands are used in research & development and to constantly benchmark the manufacturing process and H2 component quality. To guarantee the safety of media-carrying components during their entire service life, components must undergo endurance tests under extreme load and temperature changes. P+P offers and uses flexible solutions while simulating diverse conditions and environments. Our test systems allow for leak tests with a range of more than 1050 bars, depending on the specification.
The test stand can be expanded with several expansion stages. Depending on the option selected, pressure cycle tests up to 2,000 bar and 10 Hz can be generated in addition to the gas test. Pressure ramps of up to 3,000 bar can be generated with the test circuit for hydrostatic and burst pressure tests.
The system consists of two modules. The tests can be carried out in a climate chamber, in which the components can be exposed to media and outside temperatures from -40 °F (-40 °C) to +320 °F (+160 °C). The individual printing units are precisely tailored to the properties and components of the customer in order to generate ideal test conditions. A common setup in the industry and for this specific test stand is one intensifier for 1000 psi (70 bar), two for up to 4000 psi (275 bar) and one for up to 6000 psi (414 bar). A typical test medium is water, glycol, aerospace oil, gas, and other oils.
