Can the outlet pipelines of the three safety valves be combined?
Thread Content
Can the outlet pipelines of the three safety valves be combined? The diameter of the outlets is DN25. If they can be combined, what diameter should the resulting pipe have? Experts, please let me know: P
I don’t think they can be combined; they might affect each other.
I think they can be combined; I’ve encountered cases where this was done before, and DN50 is sufficient. It depends on the manufacturing process and piping; if the material tends to self-agglomerate or cause blockages, a burst disc needs to be added as an additional layer. If torch walking is required, the main pipe needs to be at 45°C, with nitrogen added at the end of the main pipe.
There are many factors to consider when merging on the outlet side, such as displacement and back pressure. If not handled properly, when one safety valve activates, its exhaust gas can affect the activation pressure of another safety valve that is still in operation. Although it is unlikely for multiple safety valves to activate at the same time, it cannot be ruled out entirely.
They can be combined, but there are requirements regarding the pipe diameter
It is feasible if discharged into a larger vessel; as for the size of the common pipeline, it depends on the actual layout, although an approximate value can be calculated based on the equivalent cross-sectional area
First of all, it’s important to clarify whether you are engaged in design work or technical upgrades. Because the setting of the extraction points for these three safety valves is crucial; factors such as the set pressure, temperature, medium, and the physical and chemical properties of the medium all need to be taken into consideration. If it’s a technical modification, it’s best to submit a report for confirmation and approval by the technical department. If it’s design,,, haha, then it’s not a problem anymore, right?
They can be combined, but it is necessary to calculate the size of the pipeline after combination. This is similar to merging them into the main pipeline in the conduit, but the size of the pipeline needs to be recalculated; it must be less than or equal to the size of the main pipeline in the conduit, and larger than that of any individual outlet pipeline before combination
Thank you. It seems they can be combined. Are there any requirements regarding the routing of the pipes?
It’s design – so why isn’t that a problem? Don’t understand
