What is the difference between a wave compensator and a metal flexible hose? I only know that metal hoses generally have a relatively thin wall thickness and are used to compensate for lateral displacement, while compensators can be selected according to their model to compensate for different types of displacement. Those with further insights are welcome to share them!
Refer to SY/T4073-94, the standard for the selection of metal hoses and bellows compensators for seismic resistance of storage tanks. Metal hoses can also compensate for axial displacement, with different internal structures
Both have similar structures; the diameter of the bellows compensator is generally larger, and it is used to compensate for axial thermal displacement or vibrations； The diameter of corrugated metal hoses is generally not large; they are mainly used to compensate for radial displacement or changes in direction. Corrugated metal hoses are generally protected with wire mesh wrapping.
Generally, large-diameter bellows compensators are used for providing lateral and axial compensation for the displacement of the entire pipeline caused by tank settlement or equipment vibration; metal hoses, on the other hand, are suitable for handling displacement in multiple directions. Therefore, in my opinion, if the installation diameter at the tank’s inlet and outlet is 700 MM or less, a metal hose should be used. Hehe, I still need more guidance from all of you experts
