Is there a mandatory requirement for electrical and instrumentation cable trays to be placed above pipes?
Thread Content
Ladies and gentlemen, regarding the piping design for Class A workshops: pipelines run above the walkways within the workshops (including those carrying heat transfer oil, steam, circulating water, instrument air, compressed air, vent pipes, exhaust pipes, and process liquids), as well as electrical and instrumentation cable trays. Is it necessary for these cable trays to be placed above the pipelines? And to avoid thermal pipelines (heat transfer oil, steam, etc.). Can we go under the pipeline? Are there any mandatory requirements? Why? Thank you!
What about the cables if the pipeline leaks?
It’s difficult to lay cables under the pipeline.
There are few leakage points, so it generally won’t leak. . . Is the cable routed downward only to account for leaks?
The cables are not laid beneath the ducts – is this mainly for reasons related to cable installation?
I don’t understand; there are always exceptions, plus the impact of lifespan.
Taking a look at the General Principles for the Layout Design of Process Piping in the petrochemical industry should be helpful to you, as it covers this topic.
Connecting a pipeline to a cable is very dangerous.
They can be laid parallel; electrical and instrumentation cable trays don’t take up much space
More people are welcome to participate in discussions and sharing. This issue needs to be taken into consideration for multi-layer pipe racks; however, they are generally installed on the top layer
