The integrity of pressure vessels is commonly assessed through hydraulic pressure testing due to the effectiveness of this method in evaluating a vessel's strength and leak-tightness. During hydraulic pressure testing, the vessel is filled with water and subjected to pressure that exceeds its normal operating conditions. This helps identify any weaknesses or potential failure points, such as cracks, leaks, or structural deformities, that may not be evident through other inspection methods.

Hydraulic testing is considered a reliable way to validate that the pressure vessel can safely handle the loads it will experience in service. Additionally, using water instead of air for the test minimizes the risk of an explosive failure, as water is incompressible and does not store energy in the same way air does.

Regular assessments using hydraulic pressure testing are essential for maintaining safety standards and prolonging the lifespan of pressure vessels, ensuring they operate efficiently and safely within their designated parameters.
