Which type of pipes are recommended for oxygen systems at high pressures?

Metal pipes are recommended for high-pressure oxygen systems due to their strength, durability, and ability to withstand the significant pressures typically encountered in these systems. Oxygen, especially at high pressures, poses certain hazards, including the risk of combustion when in contact with combustible materials. Metal pipes, such as stainless steel or carbon steel, provide a robust barrier that can safely transport oxygen without the risk of degradation or failure that could occur with other materials.

In addition to strength, metal pipes are non-combustible and have excellent compatibility with oxygen, reducing the risk of reactions that might occur with more reactive materials. Their rigid structure is also advantageous in maintaining the integrity of high-pressure systems, ensuring that there are no leaks or weaknesses that could pose safety risks.

Using alternative materials like polymeric pipes, flexible plastic pipes, or rubber hoses in high-pressure oxygen systems is discouraged because these materials can potentially fail under high pressure and may not provide the necessary fire resistance or compatibility with oxygen.
