Pressure Test Stands For
Marine & Shipbuilding-Components
At Poppe + Potthoff we serve many industries and marine and shipbuilding applications are frequently tested on our rigs. Ship engines are assembled with many components. Many of them are exposed to high pressures and thus require substantial pressure testing. Consequentially, engine parts for fuel injection such as diesel or ING, and recently also hydrogen, are tested with pressure cycle rigs and strength tests. In addition, some rails or injection nozzles are exposed to autofrettage processes. Further, ship engine cooling systems, pumps and valves are exposed to pressure and frequently tested with Poppe + Potthoff pressure test rigs.
Poppe + Potthoff offers a wide range of pressure test rigs that are utilized in the shipbuilding industry. Find a fitting rig and contact us to discuss your unique project.
Test Rig for Acoustic Emission Testing of High-Pressure Composite Tubes
Our test stand solution for Acoustic Emission Analysis (SEA) enables the early and non-destructive detection of material defects in high-pressure composite fiber tubes. With automated pressure testing up to 1,000 bar, flexible test mandrels, and integrated safety monitoring, the system offers maximum process reliability and efficiency. During the test cycle, the measurement technology captures all relevant acoustic events, ensuring complete and traceable quality documentation. In this way, you safeguard the integrity of your products and meet the highest testing standards.
Liquid Cooling Burst- and Pressure Cycle Test Rig
Poppe + Potthoff Maschinenbau leads in burst and pressure pulsation testing for liquid cooling components like coolant distribution racks, manifolds, and CPU/GPU cold plates. Our rigorous testing ensures these components can withstand extreme pressure fluctuations, with burst pressures up to 70 bar (1100 psi) and pressure cycle testing at up to 20 bar (290 psi) using PG25 coolant. We utilize both wave and square pressure curves at frequencies up to 2 Hz, providing a comprehensive simulation of operational conditions. Additionally, our testing of passive cold plates, which rely on external Coolant Distribution Units (CDUs), further guarantees system reliability by mitigating internal pump failure risks.
Burst- and Pressure Pulsation Testing Cold Plates
Poppe + Potthoff Maschinenbau’s test rigs provide essential burst and pressure pulsation testing for liquid-cooled cold plates in server technology, mirroring practices from the automotive industry. Designed to verify component durability and seal integrity under fluctuating cooling circuit conditions, our rigs handle up to 35 bar (500 psi) in burst pressure and 12 bar in pressure cycle testing with PG25, at frequencies up to 2 Hz. These tests are vital for ensuring the reliability of cooling systems in CPUs, GPUs, and similar hardware. For more information, visit our product page.
Large Components | Burst- and Pressure Cycle Test Rig
The test stand has two large chambers in which individual burst pressure and pressure cycle tests can be executed. Our state-of-the-art P+P flex pressure intensifier covers large components, such as accumulators, and generates pressure load changes of up to 800 bar with a frequency of up to 10 Hz.
Nitrogen (N) Charging Unit
The PPM nitrogen charger (PPM NCU/HA/35/400) is intended for filling large accumulator systems such as bladder, membrane and piston accumulators.
Compressed Air Booster
Our compressed air booster units are utilized where the existing compressed air supply is no longer sufficient. Consequentially our booster units increase pressure from e.g. 3 bar to up to 50 bar to meet requirements for special tools, machines or systems.
Hose Test Bench with Laser Measurement
When hoses are subjected to pressure, they often change from their original form and dimension. The test stand has an integrated automatic laser and length measurement system and can measure torsion easily. In addition, a quick connector system enables the hoses to be replaced rapidly.
Pipe and Hose Test Bench
Hoses, pipes and pipe connections must reliably withstand operational pressures and predefined pressures during testing. To prove the component and material quality, they are exposed to pressure, sometimes to the point of failure or bursting.
High-Pressure Burst Test Stand
Components are exposed to extremely high pressures during operation and must be tested for quality and material fatigue. Our high-pressure test bench for burst pressure tests up to 15,000 bar can put any component to the test.
Autofrettage for R&D and Prototypes
The autofrettage system is ideal for research and development and prototype manufacturing. The rig enables manufacturers to mount different components with a flexible fixture system. Therefore a high variety of components, designs and prototypes can be autofretted on the system.
