1. Hot water heating and cooling systems: In heating, cooling, and air conditioning systems, temperature variations can cause pipe expansion and contraction. Expansion joints are used to allow pipes to expand and contract with temperature changes, preventing damage or leaks.

2. Industrial piping systems: In industries such as chemicals, petroleum and natural gas, power generation, pipes often endure high temperatures, high pressures, and vibrations. Expansion joints are used to alleviate these stresses and extend the life of pipelines.

3. Vehicle exhaust systems: Vehicle exhaust systems, which handle high-temperature exhaust gases, use expansion joints to absorb the thermal expansion of exhaust pipes and prevent damage to the exhaust system.

4. Railways and bridges: Expansion joints are also commonly used in railway tracks and bridges to accommodate temperature fluctuations and structural vibrations, ensuring the safety and stability of the structures.

5. Wind turbines: The tower and blades of wind turbines can experience distortion and vibrations due to changes in wind conditions. Expansion joints are used to reduce these stresses and maintain the stability of the turbine.

6. Chemical plants: In chemical plants, where various chemicals are processed, which can corrode or expand pipe materials, expansion joints protect pipeline systems in different chemical environments.

7. Underground pipeline systems: Underground pipelines often need to withstand changes in soil temperature and seismic vibrations.

Expansion joints can help keep pipeline systems stable under these conditions.
