What does the term "hydrostatic testing" refer to?

The term "hydrostatic testing" refers to a method where a system is filled with water and pressurized to evaluate its integrity. This testing method is crucial in determining if there are leaks or weaknesses in a pipeline, pressure vessel, or other components of a piping system. During hydrostatic testing, water is used because it is incompressible, providing a reliable way to detect leaks. If a defect exists, the pressurized water will escape, making it clear where the failure points are.

Using this method ensures that the piping system can safely operate under the pressures it will experience during normal operations. Water also provides a safer alternative to gases, which can be hazardous under pressure. This testing is typically done after installation and periodically throughout the lifecycle of the system to ensure ongoing safety and reliability.
