Abstract:

None of the preservatives evaluated were completely removed by either hot water or low pressure steam. Dynamic low pressure steam was the most effective means of removal hot water was slightly less effective and static steam was the least effective. Preservatives with the highest percent removal were Cosmoline 1091, WS 3763, and Tectyl 5-11M. Preservatives with the lowest percent removal were Cosmoline 1046, Gulf No Rust D, and Cosmoline 1091 cutback 11 preservative-to-solvent ratio using static steam. Evaluating preity on the more realistic, weight per unit area of preservative remaining on tube surfaces, showed that, generally, Tectyl 5-11M and Tectyl 848 were the preservatives with the least amounts remaining after the various treatments. In most cases Gulf No rust D and NOKORODE had the largest amounts remaining. Inadequate corrosion protection was afforded by 3 compounds that had been solvent cutback at a 11 ratio corrosion was found under the preserved surface of the tubes.ervative removability on the more realistic, weight per unit area of preservative remaining on tube surfaces, showed that, generally, Tectyl 5-11M and Tectyl 848 were the preservatives with the least amounts remaining after the various treatments.
