Regarding the selection of gaskets for oxygen pipelines

Requirements regarding the selection of gaskets for oxygen pipelines in SH/T 3059-2012, \"Code for Selection of Materials in Petrochemical Pipeline Design\": Requirements regarding the selection of gaskets for oxygen pipelines in GB 50030-2013, \"Code for Design of Oxygen Stations\": I would like to ask everyone why, in the \"Code for Selection of Materials in Petrochemical Pipeline Design\", the selection of gaskets is not based on the design pressure, but rather polytetrafluoroethylene wound gaskets with an inner ring are chosen directly? In practical engineering, how should oxygen pipeline gaskets be selected? If a wound gasket with an inner ring is to be selected in accordance with the \"Specifications for the Selection of Materials for Petrochemical Piping\", HG/T 20610 specifies types B and D – which one should be chosen? I hope experienced friends can answer, thank you
The statement “it is advisable to use” in SH/T3059 is a recommended requirement. It’s better to choose according to national standards. The specifications of the gasket depend on those of the flanges on the pipeline.
I think the key is to carry out proper degreasing and completely eliminate oil~
Mm-hmm, mainly SH/T 3059 directly recommends PTFE wound gaskets. I’m not sure what the reasoning is behind that; it’s a bit confusing: lol
Oxygen pipelines should give priority to professional standards, namely the standards for oxygen stations
All standards specify their scope of application; it is recommended to first determine which scope applies to the project at hand before looking up the relevant standards. If the scope of application cannot be distinguished, a stricter and more stringent approach should be adopted.
