Testing and application of AST linings
- Procter and Gamble, Cincinnati, OH (United States)
AST linings are employed for three reasons: (1) to eliminate corrosion; (2) for product purity; or (3) for both 1 and 2. Test methods employed most often to determine if a lining would be acceptable is a modified Atlas Test Cell Test per NACE standard TM-01-74. This test is utilized for both thick and thin film coatings, respectively. Data gathered from this test procedure is then compared to past performance data along with any other existing data and then recorded. Before a decision is finalized and a recommendation given, other factors need to be addressed such as: design requirements; application methods; application to be used and, last but not least, inspection steps. Before lining work begins, a pre-award meeting should be held with the applicator, inspector, engineering, purchasing, safety, and appropriate plant personnel in attendance. All items of the contract should be reviewed and responsibilities of all parties agreed to. Notes should be taken and distributed to all in attendance. Application methods will be dictated by the lining system chosen. Typical methods include: spray-up; lay-up and hand-troweling. Correct inspection procedures employed before, during, and after application will enhance longevity of the life of the lining. With a sound testing program in place, utilizing a quality applicator, employing sound inspection procedures and follow up with yearly inspection of the lining, one should be able to have many years of trouble-free linings for above ground storage tanks.
