What type of test is conducted to confirm the integrity and leak rates of a piping system?

The hydrostatic test is specifically designed to confirm the integrity and leak rates of a piping system. This test involves filling the piping system with water and pressurizing it to a specified level above its normal operating pressure. By maintaining this pressure over a period of time, any leaks or weaknesses in the system can be detected. If the pressure remains stable, the system is considered to have passed the test, indicating that it is suitable for use and can withstand operational pressures safely.

Hydraulic calculations are utilized to determine the flow rates, pressures, and other hydraulic characteristics of the system but do not test for physical integrity. A flow test measures the actual flow rate available to the system, providing useful information about capacity, but it does not assess for leaks or structural integrity. A flushing test is conducted to remove debris or contaminants from the piping system and does not specifically address the strength or leak rates of the pipes. Therefore, the hydrostatic test stands out as the appropriate method for validating the integrity of the piping system.
