The expansion joint is mainly composed of pipe body, flange, expansion element and other parts.
Expansion joints are composed of multiple components, and the type and quantity of components may vary depending on the type of expansion joint. Normally, an expansion joint consists of the following components:
The expansion element is the core component of the expansion joint. It can expand and contract freely according to the expansionand contraction of the pipeline system, thereby protecting the pipeline system from damage.
The pipe body and flange of the expansion joint are usually made of carbon steel, stainless steel and other materials, which have goodcorrosion resistance and strength.
1. Choose a suitable expansion joint according to the temperature, pressure and other parameters of the pipeline system.
2.Follow the installation instructions of the expansion joint, and install the expansion joint correctly.
3.Check the working status of the expansion joint regularly, find problems in time and deal with them.
The expansion joint balance ring is used to enhance the “T” section ring of the valley and wave sidewalls, with internal pressure resistance and uniform compression displacement of each wave. Strengthening rings, circular or circular cross-sectional components are also used in U-shaped corrugated pipes to enhance the pressure resistance at the groove.
The guide bolt is installed on the expansion joint. Once the main fixed bracket fails, the limit bolt must withstand full internal pressure thrust, mainly used to limit the displacement range of the expansion joint under normal working conditions.
At the same time, prevent excessive expansion of the expansion joint corrugated pipe. After installing the expansion joint on site, it needs to be removed. The fixing bolt is used to prevent the corrugated pipe from being damaged by collision during transportation. It should be noted that expansion joints with different functions are required for different applications.
Insulation material is an accessory component of the expansion joint, used to isolate the expansion joint from other parts of the pipeline system to prevent medium leakage or damage in the pipeline system. Insulation materials are generally made of materials such as rubber and plastic.
In summary, the components of expansion joints mainly include corrugated pipes, connecting flanges, supporting components, and insulation materials. The type and quantity of these components may vary depending on the type of expansion joint.
