Are there time limits for the tank water filling test and the fixed-roof sealing and strength tests?
Thread Content
Hello, everyone! Are there time requirements for the water filling test of vertical cylindrical storage tanks, as well as the tests for the tightness, strength, and stability of fixed-roof tanks? For example, if the test pressure for the tightness and strength of the fixed roof of a storage tank is 6000 Pa, how long does it take to maintain this pressure once it has been reached? For the fixed-roof stability test, when a negative pressure of 2400 Pa is reached, how long is required to maintain this pressure? Isn’t it specified in the regulations?
This specification does not specify any time requirements
There is no time requirement; it depends on the circumstances, but usually 30 minutes is the standard.
Yes, the specifications do not specify a time limit; it has to be determined based on conventions and experience.
The water filling test for storage tanks is required to be completed within 21 days, and there are also requirements regarding the chloride ions in the water used.
