Design recommendations on HF Acid tanks

[MJCronin]

To all...

I am looking for recommendations and suggestions on the design of bulk HF acid tanks.

I have found and reviewed the well-written and useful HFIPI Guidelines but am interested in the experiernces and recommendations of other users

http://www.hfipi.org/guides.asp

Paricularly I am interested in:

- Best type of liner for 49% and 70% acid

- Recommendations on venting systems

- recommendations on level indication

- Gaskets and bolting materials recommendations

- Best type of piping systems & max design velocity

...... and anything else that is recommended

Thanks to all..... and best regards
