What type of piping is recommended for level 3 positive-pressure medical gases?

Seamless copper tubing is the recommended type of piping for level 3 positive-pressure medical gases due to its excellent properties that enhance safety and reliability in medical gas systems. Copper is non-combustible and has intrinsic antimicrobial properties, which reduces the risk of bacteria and other pathogens contaminating the gas supply.

Additionally, seamless copper tubing is resistant to corrosion, particularly in environments where it may be exposed to various chemicals or moisture. This longevity ensures that the piping maintains its structural integrity, reducing the risk of leaks or failures in the system over time, which is critical in medical applications where reliability is paramount.

The use of copper also allows for easy joining and installation due to available soldering techniques, making it easier to create secure and leak-tight connections necessary for the effective delivery of medical gases under positive pressure. These factors make seamless copper piping an ideal choice for ensuring safe and efficient operation in healthcare environments.
