What is the suitable pressure rating for a bellows corrugated expansion joint?

The suitable pressure rating for a bellows corrugated expansion joint is 2000kPa. Bellows expansion joints are designed to absorb thermal expansion, vibrations, and misalignment in piping systems. They are constructed from flexible metallic or non-metallic materials that allow for movement while maintaining a seal against pressure.

Choosing a higher pressure rating like 2000kPa ensures that the expansion joint can withstand significant pressure changes that can occur in systems involving fluids or gases under pressure. At this rating, the joint can accommodate various operational conditions while ensuring reliability and safety.

In selecting a pressure rating, factors such as material strength, application type, temperature variations, and the specific requirements of the piping system must be considered. The 2000kPa rating is generally suitable for many industrial applications, providing a balance of flexibility and durability. Lower pressure ratings may not provide the necessary safety margin required in high-pressure systems, leading to risks of failure or leaks.
