Medical gas piping is most often joined by which method?

  1. Crimping

  2. Welding

  3. Silver braze

  4. Soldering

The correct answer is: Silver braze

Medical gas piping is usually joined by silver braze because it creates a stronger and more leak-proof connection than crimping, welding, or soldering. Crimping is primarily used for joining electrical wires, not gas pipes. Welding is not recommended for medical gas piping as it can weaken the metal and create potential hazards. Soldering is also not recommended as it can leave gaps and create leaks in the piping. Therefore, silver brazing is the preferred and most common method for joining medical gas piping.
