Hangers for copper tube should be made from which material?

Hangers for copper tube should be made from copper finished or insulated materials to maintain compatibility in thermal expansion and to prevent galvanic corrosion. When copper pipes carry gases, they can expand and contract with temperature changes. Using copper or insulated hangers ensures that the hanger has a similar thermal expansion rate, which reduces the risk of stress on the tubing and maintains the integrity of the gas lines.

Additionally, copper as a material for hangers can help in preserving the lifespan of the medical gas lines by minimizing the potential for corrosive reactions that could occur if dissimilar metals were in contact with each other. Insulated hangers can also help in minimizing heat transfer, thereby preserving the desired temperatures for specific medical gas applications.
