12% HypoChlorite in PVC Pressure Main
12% HypoChlorite in PVC Pressure Main
(OP)
We have had several crack like failures in a pvc forcemain that experiences surge pressures of 140 psi. We dose this line with 12% Sodium Hypochlorite. I read a disclaimer on a plastics chemical resistance chart that said that the properties index values were only true under gravity conditions. It said that under pressure conditions some chemicals that are normally unreactive can make plastics more brittle. Are we increasing the brittlness of the forcemain by dosing with the hypochlorite?
Thank you.
Thank you.
