How is static electricity dissipated when non-metallic pipes or pipes lined with metal are used for transporting flammable and explosive liquids? ? Because of its complex composition and severe corrosion, using titanium is too expensive. I hope the expert can give some guidance!
Non-metallic pipes or pipes with a metal lining made of non-metals can be directly grounded using corrosion-resistant wires; some PTFE pipes are inherently anti-static, and the flanges as well need to be bonded together.
Antistatic materials are used during manufacturing, and additional antistatic measures are taken during installation
Here, we have replaced the vertically oriented pipelines with 304 material; the pipelines that run horizontally and are used for storing materials are lined with plastic, and they are connected across each other. However, this setup is only suitable for intermittent transfer of materials – it won’t work well for continuous flow. But you can replace the individual pipelines with corrosion-resistant materials and still connect them across as a whole
Sir, may I ask what overall bridging means? Could you please explain it in more detail? Thank you!

:(I haven’t had time to do it these past few days; it involves using copper sheets or wires to connect the various flanges that are bolted together. Generally, this is necessary for those connected with four bolts, while it’s not needed for those connected with eight bolts. Ask the people in charge of your equipment – they know what to do. For some pipelines, using all-metal components will suffice to discharge static electricity; even if there is static electricity and no air present, centralized discharge is still an option.)

I have pipes containing a medium with about 45% hydrogen, made of carbon steel lined with PTFE. We’re also worried that there might be a problem. Please ask the moderator for technical guidance, thank you
