Can anyone advise what the lowest acceptable PH would be when using Titanium GR2 in process pipe work at 80 BAR and 285ºC unfortunately I can not specify the constituants of the process fluid.

RE: titanium

According to Schweitzers Tables, you will be in trouble with HCL 20%.

Can you advise where I can find tables

RE: titanium

You need to know if there is any Cl or Fl in the fluid.  Even very small amounts will hurt you at that temperature.

Corrosion, every where, all the time.
Manage it or it will manage you.

RE: titanium

The book I have is:
Title:  Corrosion Resistance Tables
        3rd Edition, Revised and Expanded (and I'm sure there are later editions as it is about 10 years old now)
Author: Philip A. Schweitzer, P.E.
Basically the book is a collection of thousands and thousands of tests carried out by immersing all sorts of metals and non metal substances in various liquors and progressively raising the temperature until the material shows indications of incompatibility with the liquor.
If you are not prepared to disclose the make up of the liquor then investing a thousand dollars or so for this book is probaly a wise investment. I have found it most helpful as a guide, especially when comparing and adding to other peer information. McGuire is doing great stuff.
I have no connection with Schweitzer other than as a very satisfied customer.
