What is one advantage of expansion bends over expansion joints?

Expansion bends are specifically designed to accommodate thermal expansion and contraction in piping systems while maintaining the integrity of the system. One significant advantage of expansion bends is that they have a reduced chance of leakage compared to traditional expansion joints.

Expansion bends are constructed as part of a continuous pipe system, which means they eliminate the need for connection points where leaks can potentially occur, as is often the case with expansion joints that require additional connectors or seals. The smoother, continuous shape of the bend allows for even distribution of stresses caused by thermal movement, which further minimizes the risk of leakage. Thus, this design feature contributes to their reliability and overall performance in preventing leaks, making them a preferred choice in systems where leak prevention is critical.
