I would like to ask everyone: are metal wound gaskets used as sealing gaskets for gas pipeline valves on the station a problem?

If the pressure rating is sufficient, there should be no problem. Many of the gaskets used on the liquefied gas line here for propylene are wound gaskets

PTFE gaskets are commonly used in gas pipelines.

Reply to 1# dwf198208: The gaskets I mentioned are basically polytetrafluoroethylene gaskets; they offer good sealing performance and are also cost-effective

The West-to-East Gas Pipeline primarily uses flexible graphite gaskets with supports.

We use flexible graphite gaskets with positioning rings
