Currently, I am working on a water disinfection facility project. The Building specifications call for valves with chlorosufanted polethylene daiphrams such as "Hypalon". Except in chlorine solutions and chlorine gas lines we are to use valves with diaphrams made of "Teflon". The piping process we are constructing mixes potable water with with sodium hypochlorite. Our interpretation of the specification would allow us to use the the less expensive "Hypalon", since we have hypochlorite solutions rather than chlorine solutions. The valve manufacturers state that their "Hypalon" diaphrams are compatible with sodium hypachlorite. The Mechanical Engineer is demanding that we use Teflon diaphram valves for the chlorine solutions. Therefore, I would like to know if a diluted sodium hypochlorite solution meets the definition of a chlorine solution. I feel that if the Engineer in charge of writing the specification wanted Teflon diaphrams for the sodium hypochlrite process piping, then he should have written the specification just that way. There is no other process piping involved in this project except the sodium hypochlorite lines.
