Pressure Test Stands For
Marine & Shipbuilding-Components
Ship engines are assembled with many components that are exposed to high pressures and require substantial pressure testing. Engine parts for fuel injection such as diesel or ING, and recently also hydrogen, are tested with pressure cycle rigs and strength tests. For some rails or injection nozzles, autofrettage is applied. In addition ship engine cooling systems, pumps and valves are exposed to pressure and frequently tested with Poppe + Potthoff pressure test rigs.
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. The state-of-the-art flex pressure intensifier can cover large components, such as accumulators, and generate 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 due to an increased pressure requirement 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
Some 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.
Autofrettage for (Diesel) Injection Lines
With this system, high-pressure lines such as diesel injection lines (common rails) are prepared and optimized for continuous use with pulsating pressure in series. By applying the autofrettage process the service life can be increased by up to 30%.
Common Rail Serial Production Autofrettage
The rig is a uniquely developed autofrettage system for the serial production of common rails and is utilized by manufacturers to increase the fatigue strength of common rails, injection lines and other components.
Multipurpose Autofrettage
The multipurpose autofrettage system is ideal for research and development but is also well equipped for smaller serial production lines up to 13000 bar.
