pipeline

It is likely that the operating height of the valve is being taken into consideration

It seems a bit upside down; if it’s for ease of use, it would be perfectly fine to make a small stool

For ease of operation; otherwise, the height of the outlet valve is too high

If the outlet is too high, it becomes difficult to provide support, carry out operations, and perform maintenance; adding an operation platform makes things even more complicated

There are probably too many factors. Could you send a clearer photo with it facing straight ahead?

When the temperature of the medium operating the pump is high, this type of piping arrangement is adopted based on pipeline stress analysis. Adding elbows can improve the flexibility of the pipes, reduce secondary stresses in them, and lessen the stress on the pump’s outlet nozzle. Most of the centrifugal pumps produced by our company use this kind of piping configuration.

GB50316 provisions regarding piping: Pipeline layout – For pipes above the ground, it is generally specified that the pipeline layout must meet the requirements of the process as well as those outlined in the piping and instrumentation diagrams. The layout should also facilitate production operations, installation, and maintenance. It is advisable to use overhead installation; the planning and arrangement should be neat and orderly. In areas within workshops or installations where maintenance is difficult, pipes carrying highly corrosive fluids or similar substances should not be laid underground. For pipes that expand and contract due to temperature changes, flexible design considerations must be taken into account, and the extent of such considerations should not be less than what is specified in this code and in the engineering design. In the pipeline layout, pipe vibration must be controlled in accordance with the requirements set out in Article [X] of this code

Refer to various standard specifications for pipeline installation design, as well as technical guides on pressure pipeline design and approval procedures for process pipeline installation – all of which cover this topic

Personally, I think the process conditions should be considered first, followed by operational issues. Please don’t criticize my opinion if you disagree; P
