The universal expansion joint is composed of a bellows and two end joints. It absorbs the axial displacement of the pipeline through the flexible deformation of the bellows. The two end of the pipe is connected with the pipe, and the fixed stud is the rigid support of the bellows during the transportation.
Displacement direction: axial (a small amount of transverse, angular direction)
The universal expansion joint is a compensation device used to absorb the size changes caused by the heat expansion and contraction of pipelines, tubes or vessels by the effective expansion and deformation of the elastic elements of the bellows compensator, which belongs to a compensation element. The absorption of axial, transverse and angular displacement can be used for heating displacement, mechanical displacement, vibration absorption and noise reduction in pipelines, equipment and systems.
In the course of construction, general expansion joint is mainly used to compensate for axial displacement, also to compensate lateral displacement or axial and lateral displacement, and to compensate angular displacement, but generally do not apply it to compensate angular displacement. The above data is atmospheric pressure 1.0MPa. If there is special requirement for general corrugated compensator, it can be made separately.
A general expansion joint is a building material pipe consisting of a bellows (an elastic element) and an end tube, a support, a flange, a pipe and so on. It also belongs to a compensation element. The effective expansion deformation of the bellows of the main body is used to absorb the size changes caused by heat expansion and shrinkage, or to compensate for the axial, lateral and angular displacement of pipelines, ducts and vessels.
Expansion joints are often called expansion joints. It is composed of bellows (an elastic element) which is the main body of its work, and accessories such as end pipe, bracket, flange, conduit and so on.
It belongs to a compensation element. The effective expansion deformation of the bellows of the main body is used to absorb the size changes caused by heat expansion and shrinkage, or to compensate for the axial, lateral and angular displacement of pipelines, ducts and vessels. It can also be used for noise reduction and vibration reduction. It is widely used in modern industry.
Expansion joints are also known as extender and ripple compensator. The compensator is divided into several types, such as ripple compensator, sleeve compensator, rotary compensator, square natural compensator and so on. The corrugated compensator is more commonly used, and the compensator is mainly to ensure the safe operation of the pipeline, and it has the following functions:
A compensates for axial, transverse and angular thermal deformation of the absorption pipeline.
B bellows expansion compensator to facilitate installation and removal of valve piping.
C absorbs the vibration of equipment and reduces the impact of equipment vibration on the pipeline.
D absorbs the deformation of pipelines by earthquakes and subsidence.
