Hydrostatic testing is a method used to check the integrity and strength of pressure vessels, pipes, and tanks. During this process, the object is filled with water and pressurized to a level higher than its normal operating pressure. This helps identify any leaks, weaknesses, or structural issues that may not be visible during a visual inspection. The test is essential for ensuring safety and compliance with industry standards. If any leaks or failures are detected, repairs can be made before the equipment is put back into service. This testing is commonly used in industries such as oil and gas, water supply, and manufacturing.
