The bellows compensator has always had an irreplaceable position in the pipeline field. The key is the connection of the pipeline, which is very convenient for the replacement and maintenance of the pipeline. Bellows compensator is divided into two major types: flange bellows compensator and welded bellows compensator. Different types of bellows compensators correspond to different requirements in the pipeline field. The bellows compensator is an indispensable part in the pipeline field, which gives a very large use value for the pipeline field.
The corrugated compensator is a tubular compensation machine with axial corrugations made of single-layer or multi-layer thin-walled metal tubes. When working, it uses the corrugated deformation to complete the pipeline thermal compensation. The corrugated pipe used on the heating pipe network is made of stainless steel. classification of bellows compensator:
According to the classification of corrugated shape, can be divided into: "U" shaped corrugated and "n" shaped corrugated.
According to the type of compensation, it can be divided into: axial type, horizontal and vertical type (compound tie rod), angular type (articulated) and other types.
Axial type bellows compensator can absorb axial displacement, according to its pressure type can be divided into internal pressure type and external pressure type.
The horizontal and vertical bellows compensator can deform along the axial direction of the compensator, and is often installed in the horizontal and vertical pipes in the pipeline to absorb the thermal expansion of the pipeline.
The angle-type bellows compensator can bend and deform with its hinge axis as the center, similar to the spherical compensator, which must be installed in pairs on the corner section to complete the pipeline thermal compensation.
Fatigue life: refers to the number of cycles that a certain type of corrugated compensator should maintain without destruction when the displacement range value reaches the rated value under the specified nominal pressure level.
