Issues with the pressure values recorded in pipeline system pressure testing?
Thread Content
In the pressure testing records for pipeline systems, there are many pipelines under the same testing group, each with a different design pressure. If I consider them as one group and enter only the maximum pressure value, then should I record the actual pressure value or the theoretical hydrostatic test value? The pressure test values specified for formulating theories vary, but since it is the same pressure testing system, the same pressure test values should be used. How should these values be determined?
It is not recommended to connect them in this way. If the design pressure is different, the test pressure should also be different – is the difference significant? In my opinion, the actual test pressure should be filled in.
The test value should be filled in with the actual pressure testing value. Generally, systems are classified into pressure testing packages based on the process or medium used; the design pressures within a single pressure testing package should not vary significantly.
