Product Description

The metal expansion joint is a flexible structure arranged on the container shell or pipeline to compensate for the additional stress caused by temperature difference and mechanical vibration.
The metal expansion joint is a flexible structure arranged on the container shell or pipeline to compensate for the additional stress caused by temperature difference and mechanical vibration. Because of its advantages of reliable operation, good performance and compact structure, it has been widely used in chemical industry, metallurgy, nuclear energy and other departments.

Type classification:
1.Elbow expansion joint
Bend the tube into a U shape or other shape, also known as a tension bend. It is an expansion joint that uses the elastic deformation ability of the body to compensate. It has the advantages of good strength, long life, and can be produced on site. The disadvantages are that it takes up a lot of space, consumes a lot of steel and has a large frictional resistance. This kind of expansion joint is widely used in various steam pipelines and long pipelines.
2.Bellows expansion joint
Bellows expansion joint is an expansion joint made of metal bellows. It can expand and contract along the axis, and also allows a small amount of bending. Figure 2 shows a common axial bellows expansion joint used for axial length compensation on the pipeline. In order to prevent exceeding the allowable compensation amount, protective rods or protective rings are arranged at both ends of the bellows, and guide brackets are arranged on the pipes at both ends connected with it.
In addition, there are corner and lateral expansion joints, which can be used to compensate the corner deformation and lateral deformation of the pipeline. The advantages of this type of expansion joint are space saving, material saving, easy standardization and mass production, but the disadvantage is that the service life is short.
Bellows expansion joints are generally used on pipelines with low temperature and pressure and short lengths. With the improvement of the production technology level of bellows, the application scope of such expansion joints is expanding.
3.Casing expansion joint
The casing expansion joint is composed of inner and outer casings capable of relative axial movement.
A stuffing box is used to seal between the inner and outer casings. When in use, keep both ends of the tube moving on an axis. 4.Guide brackets are installed at both ends of the expansion joint.
Its advantages are small frictional resistance to fluid flow and compact structure, but its disadvantages are poor sealing and large thrust to fixed brackets. Casing expansion joints are mainly used for water pipelines and low-pressure steam pipelines.
