Structural Features
Axial external pressure expansion joints mainly absorb axial displacement, and have the advantages of large compensation, good heat preservation performance, and residual media can be eliminated. Utilize the expansion and contraction of the bellows of its working body to absorb the dimensional changes caused by thermal expansion and contraction of pipelines, conduits, containers, etc., or to compensate for the axial, lateral and angular displacement of pipelines, conduits, containers, etc. It can also be used to reduce noise and vibration.
It is composed of one or more bellows connected in series through a middle tube, and the two ends are respectively welded to the inner sealing plate and the sealing bottom plate, and then connected to the outer pipe of the through pipe. The wave number of the bellows is more.
