On a recent tank project in South Texas at a major reﬁnery, the 400/453HT was selected as the coating of choice for this tank application. The tank holds reﬁnery process water that contains high levels of H2S. The 400/453HT was selected because system has low water permeation and vapor transmission and the 453HT has excellent chemical resistance to H2S. The application called for a NACE 2 / SSPC-SP10 near white metal blast with an anchor proﬁle of 3 to 5 mils dft. The Archco 400 was applied at an average of 5 mils dft, with the Archco 453HT at 25 to 30 mils dft. The total system was 30 to 35 mils DFT. The tank was 100% holiday tested to insure that it was pin-hole free prior to putting back in service.
