Preservation issues for 25% sodium hypochlorite solutions
Thread Content
1) The 25% sodium chlorite solution is a corrosive medium with strong oxidizing properties; therefore, storage is achieved by using a Q235B material lining for corrosion protection. What anti-corrosion materials are used, and what are the construction considerations? 2) What type of pipes should be used for transporting 25% sodium hypochlorite solution – can PE pipes be used? I earnestly ask for help and answers from professionals. Thank you.
It cannot be used; it is recommended to use F4 with a steel lining
At room temperature, fluoroplastic or fluorocarbon rubber linings for the container can be considered, as well as CPVC or neoprene. As for pipes, steel-lined fluoropolymer or PVDF, CPVC pipes are all suitable. CPVC is the most economical.
