Recommendation for using flexible connections at the inlet and outlet of horizontal centrifugal pumps in high-temperature pipelines

For high-temperature pipelines and horizontal centrifugal pumps, in order to reduce the stress on the pipe ends, since the original equipment manufacturers do not provide data such as the allowable stress on these pipe ends or their displacement values, the use of flexible connections can significantly reduce the stress on the pipe ends, while also **simplifying the stress analysis of the pipelines. Is this approach the standard practice? Is there anything I need to pay attention to? I heard that hoses tend to break and leak
Many centrifugal pumps use hoses for the inlet pipe, but I’ve never seen one that uses a hose for the outlet pipe
It’s an effective approach. If one doesn’t pay attention to the properties of the medium being transported, such as corrosion and erosion, choosing the appropriate material should not pose any problems
Hehe, I’m telling you to go to Taobao; type in “high-temperature and high-pressure flexible connection pipes” there, and you’ll have many options to choose from.
A centrifugal pump is inherently a device designed to increase pressure, and I think it’s not appropriate to use a flexible connection at the outlet
Using a hose is definitely not the best method, but it is the simplest and most straightforward one. It’s certain that it will break easily and leak easily; if it’s not a toxic or flammable substance, then the problem isn’t serious.
