Question

During the hydrostatic test, the piping shall be tested at _______ percent of the maximum working pressure, but at a pressure less than the test pressure required for the storage tank.

Answer 1

During a hydrostatic test, the piping is tested at a certain percentage of the maximum working pressure, which is usually less than the test pressure required for a storage tank. This is done to ensure that the piping can withstand higher pressures than it would normally encounter during operation.

Step-by-step explanation:

During the hydrostatic test, the piping shall be tested at a certain percentage of the maximum working pressure. The specific percentage is typically determined by industry standards or project specifications. However, it is generally expected to be less than the test pressure required for a storage tank.

For example, if the maximum working pressure of the piping is 1000 psi, the hydrostatic test may be conducted at 150% of the maximum working pressure, which would be 1500 psi. This is done to ensure that the piping can withstand higher pressures than it would normally encounter during operation.
