Hastelloy C-276 and Sodium Hypochlorite
Hastelloy C-276 and Sodium Hypochlorite
(OP)
Location: Offshore Platform
=============================
I understand Hastelloy C-276 reacts with sodium hypochlorite which is used on offshore platforms to prevent marine growth/fouling of pipework. 2 ppm is what we will normally specify for continuous dosing and for intermittent shock dosing, 4 ppm.
Can someone please advise me if these dosage rates will adversely affect the Hastelloy materials?
Thanks in advance.

I have found EdStainless to be a very good source of metal answers.
One of my experiences with sodium hypochlorite application was at temperature, and most of the Hastelloy B and C we were looking at were for the most part okay chemically, but not temperature wise.
I recall Hastelloy C4 being the final choice. But, you need to talk to someone who specialize in metal.

The only C276/hypo problems that I have ever seen are at the injection quill itself. You have to be careful there.
