Sodium Hydroxide NaOH Gasket Material

[nrobson]

Plant standards call for the use of 316SS Graphite Laminate Gaskets for 46% Sodium Hydroxide storage and distribution system.

Has anyone had experience with this type of gasket material in similar service conditions?

Medium: 46% Sodium Hydroxide
Temperature: 50 Deg. C max
Pressure: 300 kPa (44 PSI)

One of the plants I work in has 50% NaOH at ambient (up to 115° F) and about the same pressures as yours. I think we use Garlock but I am checking. I'll report back here when I find out.

Thanks!

It looks like the gasket material you linked us too is very similar to Grafoil. That's the material that I would use, but I would have to compare cost first. Grafiol is great stuff. It's one of those no brainer, go on and solve the next problem, kind of materials that this world needs more of.
