Can organic solvents such as methanol, ethanol, acetonitrile, toluene, and xylene be handled using equipment and pipes made of PP or PE materials?
No. Article 4.1.7 of the \"Technical Specifications for Non-metallic Pipes in Petrochemical Industries\" (SH/T3161-2011) stipulates clearly that non-metallic pipes shall not be used for transporting media that are flammable or pose an extremely high or high level of toxicity hazard.
Pipes are not allowed; can the equipment be made of PP or PE?
It’s not possible, right? Static electricity can easily lead to accidents; there’s no need to save such a small amount of money. Besides, those metal containers don’t cost that much either!
Can’t it be lined with PTFE either? Requirements are placed on the cleanliness of the medium
