Hello,

Polyvinylidene fluoride (PVDF), as homopolymer, can be used for piping lining only at pH < 11.A pH between 12 and 13 gives the most stable solution. Less than pH 11 decomposition of hypochloride is significant.

Google " OxyChem Sodium Hypochloride Handbook "

 

@LAXMI GOVIND

You can have a look in "Piping Handbook, by Mohinder L. Nayyar".
