Urgent: Is the electromagnetic flowmeter resistant to acids and alkalis in polyurethane?
Thread Content
I urgently need the expert advice from HaiChuan – is the polyurethane lining of electromagnetic flowmeters resistant to acids and alkalis in a pH range of 5.5 to 8? What about weak acids?
Polyurethane itself has a certain resistance to acids and alkalis, but long-term use is not recommended. A PTFE lining can be used; if you have any issues with the selection, feel free to contact me privately
Why not use PTFE... The polyurethane lining is wear-resistant
If you’re not familiar with the nuclear power industry, the common electromagnetic linings include PTFE, PFA, neoprene, FEP, and polyurethane. If none of these work, could ceramic be used?
Polyurethane is also known as PU pipes, and they are widely used. Your pH value is only slightly acidic, so there’s no problem using PU pipes; at a pH of 5.5, it won’t cause any noticeable discomfort when your hand comes into contact with them, so you can rest assured
