Sodium Hypod Chlorite Chemcial Compatibity
Sodium Hypod Chlorite Chemcial Compatibity
(OP)
We have a project here and need compatible piping material selection for Hypochlorite 12.5%, installed under shade where the ambient reaches to 55 Deg C. There is lot of piping for Hypo and require feasible selection (not Haste Alloy or with Halar Coated CS)
Further CPVC cannot be used!
Please advice!

Tanks and containers should be white or opaque to protect the product from decomposition from UV light. If possible, tanks and storage containers should be located in a shaded are. The product should be kept as cool as possible to avoid decomposition and extend the shelf life of the product. Product kept at 60°F is ideal if decomposition is a problem. Be aware that the decomposition rate is increased by a factor of 3.5 with every 10°C increase in storage temperature.
I would think that at these temperatures you will get a lot of off gassing and air locks in the piping and pumps. If you use carrier water to dilute the sodium hypochlorite you will be susceptible to precipitation of calcium carbonate in the piping and the piping will plug up quickly
Maybe you should be looking at using chlorine gas with a water injector
