The internal and external pressure balanced corrugated compensator (type) can compensate for the axial displacement of the piping system, and the internal pressure thrust balances itself. This structural product can be applied to tall straight pipelines or large-diameter pipelines where fixed brackets are not suitable. The straight pipe pressure balance compensator consists of a bellows and two end connections forming other parts.
Precautions for installation and use of internal and external pressure balanced corrugated compensator (type):
Internal and external pressure balanced corrugated compensator (type) is generally used on overhead straight pipelines and installed horizontally.
After the B internal and external pressure balanced corrugated compensator (type) is installed, all small tie rods must be removed.
In order to reduce the elastic reaction force of the bellows expansion joint on the support, this type of bellows expansion joint can be pre-tensioned or pre-pressed before installation (this can be achieved by adjusting the small tie rod on it).
The internal and external pressure balanced corrugated compensator (type) absorbs the axial displacement of the pipeline (there is also a small amount of lateral and angular displacement) through the flexible deformation of the bellows. The end pipe is either directly welded to the pipe pipe, or the flange is welded Then connect with the pipe flange. The small tie rod on the expansion joint is mainly used for rigid support during transportation or for pre-deformation adjustment of the product. It is not a load-bearing part.
The internal and external pressure balance bellows compensator (type) has a working bellows at each end and a balance bellows in the middle. The straight tube pressure balance compensator is borne by the force-bearing member (large tie rod or tongue tube) Internal pressure thrust, so the piping system only needs intermediate fixing brackets. This type of corrugated expansion joint can only absorb axial displacement.
Structural principle of internal and external pressure balance bellows compensator (type): The pressure balance expansion joint is a bellows structure, which is composed of a pressure balance bellows and a compensation bellows. The pressure of the bellows compensator is balanced through the pressure balancing bellows to relieve the compensator and the pipeline's own thrust.
