Can black PE pipes withstand 50% H2SO4?
Thread Content
I’m new to chemical processing equipment. I would like to ask: can black PE pipes be used to transport 50% sulfuric acid? It is used to add bottled sulfuric acid to the reaction vessel, and pressure need not be considered.
It should be possible; PE dissolves in professional organic solvents such as toluene and acetic acid only at 70 degrees Celsius, and its corrosion resistance is quite good!
PE has no problem in terms of corrosion resistance, but its temperature resistance is somewhat poor and it deforms significantly; it is recommended to use plastic composite pipes with a steel framework – the addition of such a framework greatly improves their temperature and pressure resistance.
