What is your understanding of the bending and stretchability of vacuum bellows?

The bending and elasticity of vacuum bellows are important performance characteristics,and the following is my specific understanding of these two characteristics:
Flexibility
Vacuum bellows,due to its corrugated busbar,has high flexibility and can be bent within a certain range.This flexibility allows vacuum bellows to adapt to various complex installation environments and space limitations,without the need for excessive joints and elbows,thus simplifying the design and installation of pipeline systems.Meanwhile,the bending of corrugated pipes can also reduce stress and fatigue caused by pipeline vibration and displacement,improving the stability and reliability of pipeline systems.
Scalability
The scalability of vacuum corrugated pipes is another significant feature.The structure of corrugated pipes allows their length to change under pressure,axial force,lateral force,and bending moment.Under the action of tension,the length of the corrugated pipe will be elongated;Under the action of compression force,its length will be shortened.This scalability enables vacuum bellows to adapt to changes in temperature and pressure,as well as thermal expansion and cold contraction of pipeline systems.In addition,the scalability of corrugated pipes also enables them to have a certain effect on shock absorption and noise reduction,which can improve the operating environment and performance of pipeline systems.
The range of expansion and contraction
Generally speaking,the expansion and contraction of vacuum bellows is between 5%and 30%,depending on the type,material,and design of the bellows.The expansion and contraction within this range can meet the needs of most pipeline systems,enabling corrugated pipes to maintain stable performance under various working conditions.
In summary,the bending and scalability of vacuum corrugated pipes are important performance characteristics,enabling them to perform excellently in various complex pipeline systems.
