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.

Burst Test Rig

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.

Compressed Air Booster

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

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.

Burst Test Rig

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.

Burst Test Rig

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.

Burst Test Rig

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.


Autofrettage for (Diesel) Injection Lines

High-pressure lines such as diesel injection lines (common rails) are autofrettaged for continuous use with pulsating pressure in series production. By applying the autofrettage process component service life can be increased by up to 30%.


Common Rail Serial Production Autofrettage

This state-of-the-art autofrettage system is the perfect solution for the serial production of common rails. Our flagship system is utilized by manufacturers around to world. It enables improvement of the fatigue strength of common rails, injection lines and other components.


Multipurpose Autofrettage

Our multipurpose autofrettage system is ideal for research and development. In addition, is also well equipped for smaller serial production lines up to 13000 bar.
