Seeking advice on the selection of gasket for gas pipelines
Thread Content
I have a question for the technical experts here. I have a client who uses methane as the medium in their pipelines. For the valves used in these systems, we chose butterfly valves with PTFE gaskets. The supervisor now claims that high-speed flow of dry methane can generate static electricity when it comes into contact with the PTFE gaskets in the butterfly valves; since this static electricity may not be able to escape from within the valves, it could pose a danger. He wants us to replace all those PTFE gasketed butterfly valves – are there any reasons why this theory might not be correct? **Could you please specify the standards for selecting gaskets in the gas industry? I need a standard number to give to the supervisor. Thank you!
Generally, static electricity bonding is carried out, with all connections brought together and linked to the on-site grounding system.
Static bonding is generally applied to gas pipelines
