Product introduction of metal compensator:

There are two types of connection forms for universal metal compensators, namely welded universal metal compensators and flanged universal metal compensators. The welded universal bellows compensator directly welds the two ends of the pipe to the pipeline, while the flanged universal bellows compensator welds the flange on the pipe and connects it to the pipeline with the flange and fasteners.

Model representation of universal bellows compensator:

If the model of the universal bellows compensator is: 1.6YGTB2800×6J, it means that the second universal bellows compensator is a universal bellows compensator with a diameter of 2800, a pressure of 1.6MPa, a bellows with 6 corrugations, and a carbon steel pipe connection.

Structural features of universal bellows compensators:

The universal bellows compensator consists of a stainless steel bellows, two end pipes and other parts. The compensator absorbs the expansion of the pipeline caused by the temperature difference through the flexibility of the bellows. The universal bellows compensator can absorb the axial displacement of the pipeline and a small amount of lateral displacement and angular displacement.

There are two types of connection forms for universal bellows compensators, namely welded universal bellows compensators and flanged universal bellows compensators.

The welded universal bellows compensator directly welds the two ends of the pipe to the pipeline, while the flanged universal bellows compensator welds the flange on the pipe and connects it to the pipeline with the flange and fasteners.

The small pull rod on the universal bellows compensator is also called the transport pull rod. It is mainly used for rigid support during transportation or for pre-deformation adjustment of the compensator. It is not a load-bearing part. This type of compensator has a simple structure, low price, and is easy to install and use. Therefore, when the pipeline needs to use a compensator, the universal bellows compensator is a preferred compensator form.

Notes on installation of universal bellows compensator:

• The direction of the guide tube should be consistent with the flow direction of the medium in the pipeline (there is a flow direction mark on the compensator);
• After the on-site installation is completed, the small pull rod on the universal bellows compensator must be removed;
• In order to reduce the force on the pipe rack, if the universal bellows compensator needs to be pre-stretched and compressed before installation, it must be proposed when ordering the compensator, and it cannot be operated privately.

Application of universal bellows compensator：

When using universal bellows compensators, it is necessary to consider the displacement of the pipeline and reasonably set the pipeline support and hanger.

In the case of lateral displacement or axial and lateral combined displacement, the limitation of using universal bellows compensators is mainly the limited ability of the compensator to absorb lateral displacement.

In addition, in the case of high working pressure, high temperature, large diameter or in the case of inability to install the main fixed bracket or multiple guide brackets on the structure, the use of universal bellows compensators may not work. At this time, it is necessary to contact technicians to replace the form of the compensator.
