What material is best for piping systems in aluminum chloride polymeric aqueous solutions?
Thread Content
1. The polyaluminum dosing pump is a metering pump with a head of 50 meters. 2. The material of the pump outlet pipe is PVC, and material leakage often occurs at the pipe connections. 3. The pH of the material is 4, and the chloride ion concentration is 5000 mg/l. I want to know what methods can be used to solve the material leakage problem, such as changing the pipe material or adjusting the pump parameters.
The corrosion resistance of some materials is good; many pipes use PTFE lining or PO lining, offering high acid resistance. 13668620835 – same WeChat ID
