Hydrotest and pneumatic test for piping

Question

Accepted Answer

Hydrotest and pneumatic test are methods used to test the integrity of piping systems.

Hydrotest involves filling the piping system with water and pressurizing it to a specified level for a set duration.
Pneumatic test involves filling the piping system with compressed air or nitrogen and pressurizing it to a specified level for a set duration.
Both tests are used to ensure that the piping system can withstand the expected operating pressure without leaking or rupturing.
Hydrotest is typically used for systems that will carry liquids, while pneumatic test is used for systems that will carry gases.
The test pressure and duration are specified in the project specifications or applicable codes and standards.
After the test is completed, the piping system is inspected for leaks or damage.
If any leaks or damage are found, the piping system must be repaired and retested before being put into service.
