What joint types are permitted for medical gas piping?

The correct choice indicates that gauges and sensors are specifically relevant to the operation and monitoring of medical gas piping systems, rather than being a type of joint used for connecting pipes. Gauges and sensors play an essential role in ensuring the safety and functionality of medical gas systems by monitoring pressure and detecting leaks.

In medical gas piping installations, ensuring the integrity and safety of joints is critical, and various methods, such as soldered and welded joints, are utilized based on the specific materials and requirements of the gas being delivered. Each type of joint has its applications and standards that align with regulations governing medical gas systems. Thus, understanding that gauges and sensors serve a different purpose underscores the importance of safety monitoring in conjunction with the types of physical connections made in the piping system. This choice clarifies the distinction between the components involved in a medical gas system and the infrastructure itself.
