Pressure Test Stands for Hydrogen (H2) Components

Pressure Cycle Test Bench | Burst Test Bench | Hydrostatic Fatigue Testing | Testing with Coolant, Oil, Water and more

Poppe + Potthoff Maschinenbau GmbH develops test systems for research & development and validation of media carrying hydrogen components. At Poppe + Potthoff we offer test stands in the field of pressure pulsation testing, pressure cycle testing, burst pressure testing and hydrostatic (fatigue) testing. The test benches are used in various component testing setups. Some examples are: shut-off valves, connection parts for containers, flexible fuel lines, non-return valves, pressure regulators, pressure reducers, pressure relief valves, flow sensors and sensors for detecting hydrogen leaks. In order to test the test parts for their design life or to find material compositions in the area of ​​research and development, test parts are subjected to pressure tests, sometimes at ambient temperatures. Contact us today and we look forward to working on your project.

Pressure Pulsation & Burst Test
Stand: 1x Chamber + 1x Climate Chamber

Pressure Cycle Test Bench
up to 700 Bar for H2 Systems

Burst Test Stand

Pressure Cycle & Burst Test
Bench with two Chambers

Exemplary test bench with Pressure Pulsation and a climate chamber for H2 Components at it’s core. Burst test and Hydrostatic Fatigue test capabilities can be added or purchased as stand alone test bench.

R&D Pressure Pulsation Test Stand for H2 Components up to 2000 bar

The system is a self-sufficient unit and is made of a solid welded frame, contains media preparation, a hydraulic unit and electrical engineering. The pressure test bench has a secure test chamber for burst pressure and hydrostatic pressure tests and, optionally, a climatic chamber for pressure tests with environmental simulation.

Depending on the option selected, pressure change tests up to 2,000 bar and 10 Hz can be generated. With the test circuit for hydrostatic and burst pressure tests, pressure ramps up to 3,000 bar can be generated. It is operated on a support arm PC.
