What material is commonly used for the piping of medical gas systems?

Copper or aluminum pipes are commonly used for the piping of medical gas systems due to their excellent mechanical properties, resistance to corrosion, and ability to maintain the purity of the gas being transported. Copper is especially favored because it has natural antimicrobial properties and is durable, making it highly suitable for environments like hospitals where hygiene is critical. Aluminum is lightweight, resistant to corrosion, and can also be used in medical gas systems, especially when weight is a consideration in the installation.

In contrast to the other materials, plastic tubing and PVC may not be suitable for all medical gas applications due to concerns about durability, potential for gas contamination, and structural integrity at high pressures. Rubber hoses, while flexible, are generally not used for permanent installations due to issues with wear and safety when transporting compressed gases. Thus, copper and aluminum pipes stand out as the optimal materials for ensuring both compliance with health standards and the reliability of medical gas systems.
