Regarding the issue of whether bellows compensators can be used under high pressure
Thread Content
I am currently working on a project involving the overhead installation of pipelines. The operating temperature should not exceed 85°C, the pressure is 4 MPa, and the fluid being transported is refined crude oil. The pipeline diameter is DN250, and the client requires the use of bellows compensators for thermal compensation. I asked the experts in our thermal engineering field, and they all advised against using bellows compensators under high pressure, as the quality of production cannot be guaranteed. I would like to ask whether it is possible to use bellows compensators under high pressures. Does anyone know in which specific projects bellows compensators are used under high pressures with flammable and explosive media, and which brand of such compensators is employed?
It is unwise to use compensators under high pressure, but if the right model is chosen, there should be no major problems
4MPa; try to avoid using this situation, and it is recommended to use a U-shaped bend instead.
I have never used wave compensators under high pressure; the operating conditions for wave compensators are quite demanding
Do not use bellows compensators; it won’t work. If the site is too crowded, other solutions must be found, such as U-shaped compensators or something like that
Does Party A not have any process engineers? It should also be understood that under such high pressure, U-shaped pipe compensators must be used to ensure the safe operation of the pipes.
