What is likely a disadvantage of using screwed connections in piping?

The choice identifying a higher risk of leaks as a disadvantage of using screwed connections in piping highlights a significant concern in piping systems. Screwed connections rely on threaded fittings to maintain a seal. Over time, vibrations, thermal expansion and contraction, or even improper tightening can lead to these connections loosening. If a screwed joint is not properly maintained or if it experiences stress or corrosion, the likelihood of leaks increases, which poses risks to both safety and efficiency within the system.

In addition, as the conditions around the piping change—such as temperature fluctuations—the integrity of the threaded joint can deteriorate further, exacerbating potential leak issues. Ensuring leak-free operations is critical in any power engineering application, making the reliability of connection types an essential consideration.

Other options may relate to different factors, but the fundamental concern for many engineers lies with the integrity of the joints, making leak risk a prominent disadvantage associated with screwed connections.
