Can stainless steel be used as the material for oxygen filling busbars?
Thread Content
I checked the \"Specifications for Oxygen Stations\" (GB50030-2013). Regarding the material used for oxygen manifolds (with a filling pressure of around 15 MPaG), stainless steel pipes cannot be used; copper or nickel pipes are required. I’m not very familiar with this area, and the client said that all the manifolds are made of stainless steel, without any use of copper pipes. Does anyone know anything about this? ?
\"GB16912-2008 Safety Technical Regulations for the Production of Oxygen and Related Gases by Deep Freezing Method\", Table 10 \"Table of Materials Suitable for Oxygen Pipelines\".
As long as the flow rate remains within the specified range, it is acceptable. However, copper pipes are the best, but welding requires certain technical skills. It is also common to use non-stainless steel. Compliance is mandatory; otherwise, the supervision authorities will not issue the relevant permits.
