The Hydrostatic Test Machine is a device used to assess the strength, leakage, and pressure resistance of tanks, pipes, and pressure-bearing components. This machine applies high pressure using water or other fluids to the test specimen to identify weak points, cracks, or leaks.
Operation and Working Principle of the Hydrostatic Test Machine
Filling the tank or pipe with water or test fluid
The tank or pipe is completely filled with water, and air is removed to ensure uniform pressure application.
Applying high pressure to simulate working conditions
A high-pressure pump delivers water at a pressure above the standard limit into the system.
The test pressure is usually 1.5 to 2 times the normal operating pressure of the tank or pipe.
Monitoring deformation and leaks
If cracks or holes exist, water will leak from them.
Digital sensors record pressure variations to identify weak points and material wear.
Draining the fluid and final inspection
After the test, the water is drained, and the internal and external surfaces of the tank are inspected.
Test data is stored in the system, and a final report is generated.
