How to correctly select the corrugated metal compensator to ensure that the corrugated compensator to play its advantages have several.
Before selection, communicate with professional designers, measure data according to field conditions, make accounting, list the nominal diameter of the appropriate compensator, medium, compensation mode and compensation amount, high and low temperature resistance range, high and low pressure resistance range, connection port size, etc., and then the following.
2 . Select the appropriate number of waves, according to the use of bellows, compensation volume size and other factors, consider the number of compensator fatigue under stress, select the appropriate deformation stress is small, fatigue-resistant corresponding wave number.
3 . Whether you need to add a guide device, according to some compensators work for a long time, will produce column instability, should add some guide device.
4 . Whether to strengthen the ring, according to some compensators to adapt to higher working pressure, appropriate to increase the strengthening ring or multi-layer structure. Strengthening ring is local strengthening, multi-layer structure is overall strengthening.
5 . Connection, according to the compensator and the pipeline or the corresponding equipment port situation, can choose flange connection, clamp connection, welding connection. Choose flange connection, we must choose the appropriate flange according to the diagram, the flange technology to meet the corresponding standards for the specification, in practice, often choose the wrong flange, this must pay attention to, once the wrong choice, it will affect the use of the entire pipeline, resulting in the loss of the compensator pipeline.
