Product Description

An expansion joint (also called an expansion joint, expansion joint or compensator) is a flexible connection device used in a pipeline system. It is mainly used to absorb the displacement and deformation of the pipeline caused by temperature changes, mechanical vibration or foundation settlement. It can effectively reduce pipeline stress and prevent the pipeline system from being damaged by thermal expansion and contraction or other external forces.

Main functions of expansion joints

1. Compensation for thermal expansion and contraction:
- Pipes will expand and contract when the temperature changes. Expansion joints can absorb this displacement and prevent the pipeline from being damaged due to excessive stress.
2. Absorb vibration:
- When pumps, compressors and other equipment are running, the pipeline may vibrate. Expansion joints can absorb vibration and protect pipelines and equipment.
3. Compensation for installation errors:
- During the installation of pipelines, there may be certain errors. Expansion joints can compensate for these errors and ensure the normal operation of the pipeline system.
4. Adapt to foundation settlement:
- In the case of uneven foundation settlement, expansion joints can absorb the displacement of the pipeline and avoid pipeline breakage.

Main structure of expansion joint
1. Bellows:
- The core component of the expansion joint, usually made of stainless steel or other metal materials, with good flexibility and pressure resistance.
2. Flange or threaded connection:
- Used to connect the expansion joint to the pipeline system.
3. Limiting rod:
- Used to limit the displacement range of the expansion joint to prevent excessive stretching or compression.
4. Inner sleeve:
- Used to protect the bellows from medium erosion or corrosion.
5. Outer cover:
- Used to protect the bellows from external mechanical damage.

Application scenarios of expansion joint
1. Heating pipeline:
- Used to absorb the thermal expansion and contraction of the pipeline caused by temperature changes.
2. Chemical pipeline:
- Used to compensate for the displacement of the pipeline caused by medium temperature changes or chemical reactions.
3. Power industry:
- Used for steam pipelines, cooling water pipelines, etc., to absorb thermal expansion and contraction and vibration.
4. Water supply and drainage system:
- Used to absorb the displacement of pipelines caused by temperature changes or foundation settlement.
5. Oil and gas industry:
- Used for long-distance pipelines to compensate for temperature changes and foundation settlement.
6. Ship and marine engineering:
- Used to absorb vibration and displacement of ship piping systems.
