Chlorine engineering battery tank inlet pipe

Experts who use chlorine engineering cells are asked to discuss what materials are used for the salt water pipelines and circulating salt water pipelines that enter the cells after the chelating resin is used in chlorine engineering cells. What materials are used for the circulating alkali liquid pipelines? # , , &
:) At present, our company uses titanium materials
The brine pipeline is made of titanium. What material is the alkali pipeline made of? It can’t be titanium.
For the secondary refined brine coming out of the chelating resin tower and entering the electrolytic cell, it is best to use Ti pipes for this part, or C-PVC (Low Ca Mg, I don’t know if the quality of domestic PVC is acceptable at present). Circulating brine is the same as above. Ni pipes can be used for circulating alkali liquid. Of course, the price is very high. Steel-lined PTFE or PP+FRP can also be used.
Use titanium tubes for brine and 310S for circulating alkali solution.

What kind of pipeline is PH? I have never heard of it. Please explain.
We all use steel lined PTFE pipes.
Steel-lined PTFE pipes have safety hazards. Once the lining falls off, it will seriously affect the operation of the battery tank and cause accidents.
PPH pipe is polypropylene pipe, but the processing technology is different from PP pipe.
The temperature of the secondary refined brine from the chelating resin tower to the electrolyzer section is not very high, so C-PVC (low Ca Mg) is used. However, the circulating brine pipeline has a relatively high temperature and contains more free chlorine and acid, so titanium is more suitable. The circulating alkali solution uses steel lined with PTFE, but emergency measures should be taken after the lining is damaged. ； Stainless steel is also used. It will corrode to a certain extent after being used for a long time, which will have a certain impact on the film. ； Of course, if possible, it is best to use Ni. They all work well within the temperature range.
PPH pipes are also very good. The inner lining is relatively strong, much better than PP pipes. In the section of the pipeline entering the electrolytic tank, there is a fear that the lining will fall off and block the pipeline. The consequences will be serious and difficult to check:)
