Prüfdruck

Prüfdruck, often translated as test pressure or proof pressure, is a term used in engineering and manufacturing to denote a specific pressure value applied to a component or system during testing. This test is conducted to verify the integrity, strength, and safety of the item under conditions that exceed its normal operating pressure. The purpose of applying a Prüfdruck is to detect potential weaknesses, leaks, or defects that might not be apparent under standard operational loads.

The level of Prüfdruck is typically set at a multiple of the intended working pressure. This multiple is determined by industry standards, regulatory requirements, and the specific application of the component or system. For instance, in the context of pressure vessels, pipelines, or hydraulic systems, a higher Prüfdruck ensures that the component can safely withstand unexpected pressure surges or excursions beyond its normal operating range.

During a Prüfdruck test, the system is pressurized to the specified value and held for a defined period. Inspectors then examine the component for any signs of deformation, leakage, or failure. Successful completion of the Prüfdruck test indicates that the component meets the required safety and performance standards. Failure to withstand the Prüfdruck necessitates investigation into the cause of the failure, followed by repair or replacement of the defective part. This rigorous testing procedure is crucial for preventing catastrophic failures and ensuring the safety of personnel and equipment.
