Denso Archco™ protects Hot Oil Pipelines
Industrial Coatings & Linings
The engineer responsible for the project chose not to replace the asphalt system, instead preferring an epoxy coating with high heat resistance up to 250˚F. After difficulty finding a coating that could withstand both a 250˚F service temperature and the presence of H2S in the surrounding soil, the engineer contacted Denso for a solution.
Having experience with similar types of aggressive service in the past, Denso recommended the Archco 453HT™ due to its excellent resistance to high heat and H2S. The pipeline was first blasted to a NACE 2 Near-White Blast, and the Archco 453HT was spray applied in one coat at 30 mils DFT.
The contractor and engineer were very pleased with the success of the application.
