Question

For threaded gas piping systems of 200 feet or less with a working pressure of 10 psig, the minimum test duration shall be:

a) 10 minutes
b) 15 minutes
c) 30 minutes
d) 60 minutes

Answer 1

For threaded gas piping systems of 200 feet or less with a working pressure of 10 psig, the minimum test duration shall be 60 minutes to ensure the integrity of the system.

Step-by-step explanation:

For threaded gas piping systems of 200 feet or less with a working pressure of 10 psig, the minimum test duration shall be 60 minutes. When testing a gas piping system, it is essential that the test is conducted for a sufficient amount of time to ensure there are no leaks and that the system can hold the specified pressure safely. For threaded gas piping systems of this length and pressure, a 60-minute test is the minimum standard to assess the integrity of the piping.
