A bellows corrugated expansion joint is suitable for pressures up to approximately how many kPa?

A bellows corrugated expansion joint is designed to accommodate thermal expansion and provide flexibility in piping systems, especially in refrigeration and HVAC applications. The typical operational pressure limit for this type of expansion joint is generally around 2000 kPa (kilopascals). This limit ensures that the joint can effectively handle the pressure without compromising its structural integrity or performance.

Among the other options, pressures exceeding 2000 kPa may lead to failures or leaks in the bellows, as they aren't engineered to safely operate under such extreme conditions. Thus, while options indicating higher pressures may seem appealing, they do not reflect the standard design limits for bellows corrugated expansion joints in practical use. Therefore, recognizing that 2000 kPa is the accepted threshold helps in understanding the appropriate application of these components in mechanical systems.
