For medical gas pipeline systems design and installed, due to gas variety and composition complex, flammable and toxic gases leakage are all may produce an accident. Therefore, hospital indoor installation medical gas alarm is necessary to achieve safe conditions of production. In short, at standard gas preparation process must be prepared for the medical gas research, development of rational filling process and safety procedures provides the necessary safety conditions. Medical gas pipeline engineering medical oxygen gas manifold under certain conditions with gas cylinders, valves, medical gas piping material may dangerous as follows:

1. Caustic
        1) moisture corrosion
        2) stress corrosion

2. Create dangerous compounds
