Druckhalteprüfungen

Druckhalteprüfungen, also known as pressure holding tests or leakage tests, are essential procedures in various industrial and engineering applications to verify the integrity and tightness of a system under pressure. These tests are conducted to ensure that a system, such as pipelines, vessels, or hydraulic components, can maintain a specific internal pressure over a defined period without significant loss. This is crucial for preventing leaks, which can lead to safety hazards, environmental damage, material waste, and operational failures.

The fundamental principle of a Druckhalteprüfung involves pressurizing the system with a suitable medium, typically a gas like nitrogen or air, or a liquid such as water. Once the desired test pressure is reached and stabilized, the pressure source is isolated. The system is then monitored for any drop in pressure over the specified duration. A stable pressure indicates that the system is leak-free, while a declining pressure suggests the presence of leaks.

The execution of a Druckhalteprüfung requires careful planning and adherence to established standards and protocols. Factors such as the type of system being tested, the operating pressure, the test medium, and the ambient conditions all influence the test procedure and acceptance criteria. Specialized equipment, including pressure gauges, regulators, and data logging devices, are used to accurately measure and record pressure changes. These tests are vital for quality control, regulatory compliance, and ensuring the long-term reliability and safety of pressurized systems.
