Flake Glass Reinforced Vinyl Ester
Flake Glass Reinforced Vinyl Ester
(OP)
Have a 0.375 in. shell and head tank with internal Flake Glass Reinforced Vinyl Ester coating system (3 coats totaling 50 mils)and coated externally with Semcrete No. 954 Epoxy (12 mils).
1. Is it possible that when we take thickness measurements from the outside of the tank that the sound wave propagates throught the Vinyl Ester coating and reflects back and is included in our thickness readings? We are using a simple StresTel T-Mike E thickness gage. We are getting readings in the mid 0.400's.
2. Do we have to much tank for our little thickness gage? 3. Do we need to invest in a gage with B-Scan or A-scan capabilities to seperate the differ signals?
