Is plastic lining suitable for sulfuric acid pipelines?
Thread Content
I would like to ask everyone whether plastic-lined pipes are suitable for transporting sulfuric acid
Yes, it is usually F4 with a steel lining.
Lined plastics won’t work; they will oxidize, especially with concentrated sulfuric acid.
The use of plastic lining is theoretically sound, but there is a problem: plastics are not resistant to wear, and although they may work for a while, the steel pipe still needs to be replaced eventually.
Specifically, consider parameters such as the temperature, concentration, and pressure of the sulfuric acid being transported; too high a temperature or pressure is not acceptable.
It depends on your sulfuric acid concentration and temperature
The two distinct properties of sulfuric acid – its oxidizing and reducing capabilities – determine the suitability of plastic-lined pipes. Of course, PTFE lining can also be used, but this is considered from an economic perspective.
Sure, as long as the operating conditions meet the requirements for fluorinated lining pipes. Concentration isn’t important; it’s temperature, pressure, and so on that matter 412372706
Dilute sulfuric acid can be used as long as the scouring is not intense
It depends on your concentration and temperature; at room temperature, 98% concentration with carbon steel is sufficient; we can discuss further if it’s a weaker concentration.
