drukwaterproef

A drukwaterproef, often translated as a pressure water test or hydrostatic test, is a method used to verify the integrity and leak-tightness of a closed system, typically piping or a vessel, by filling it with water and then pressurizing it to a specific level. This testing procedure is commonly employed in various industries, including construction, plumbing, and manufacturing, to ensure that the system can safely withstand its intended operating pressures and is free from defects.

The process involves isolating the system to be tested and then filling it with water, often with an additive to prevent freezing or corrosion. Once completely filled, air is purged from the system to ensure it is entirely water-filled. The water is then pressurized to a predetermined test pressure, which is usually a multiple of the system's maximum working pressure, as specified by relevant codes and standards. This pressure is maintained for a specified duration, during which the system is monitored for any signs of leakage, such as dripping water or a drop in pressure.

If the pressure remains stable throughout the testing period and no leaks are observed, the system is deemed to have passed the drukwaterproef. If leaks are detected, they must be identified and repaired before a re-test can be performed. This test is crucial for preventing potential failures, such as burst pipes or leaks in storage tanks, which could lead to significant damage, safety hazards, and costly repairs. It is a fundamental quality control measure in many engineering applications.
