Product Description

The flange limit joint (also called limit expansion joint or limit compensator) is a special pipe connection device, which is mainly used to absorb the axial displacement, lateral displacement and angular displacement of the pipe, and prevent the pipe from being damaged due to excessive displacement through the limit device. It combines the functions of expansion joints and limit devices and is widely used in pipeline systems that require strict control of the displacement range.

Main functions of flange limit joints
1. Displacement absorption:
- It can absorb the axial, lateral and angular displacement of the pipe caused by thermal expansion and contraction, vibration or foundation settlement.
2. Limit protection:
- Prevent the pipe from being damaged due to excessive displacement through limit devices (such as limit rods or limit bolts), ensuring the safe operation of the pipeline system.
3. Reducing stress:
- By absorbing displacement, reduce stress concentration in the pipeline system and extend the service life of the pipeline and equipment.
4. Easy installation and maintenance:
- The flange connection method is easy to install and disassemble, and easy to maintain.

Main structure of flange limit joint
1. Bellows:
- Core component, usually made of stainless steel or other metal materials, with good flexibility and pressure resistance, used to absorb displacement.
2. Flange:
- Used to connect pipeline systems, usually using standard flanges (such as national standard, American standard, German standard, etc.).
3. Limiting device:
- Including limiting rods or limiting bolts, used to limit the displacement range of the bellows to prevent excessive stretching or compression.
4. Inner liner:
- 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 flange limit joint
1. Heating pipeline:
- Used to absorb the thermal expansion and contraction of the pipeline caused by temperature changes, and prevent excessive displacement through the limiting device.
2. Chemical pipelines:
- Used to compensate for the displacement of pipelines caused by medium temperature changes or chemical reactions, and protect pipeline systems.
3. Electric 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.
