Innovative Coating System for Corrosion Prevention and Temperature Reduction in Heat Distribution Manholes

Provide means to better protect manhole piping. Even in normal operation the warm-to-hot and often humid manhole environment is inherently prone to accelerated corrosive degradation. During their normal service life piping in heat distribution system (HDS) manholes throughout the Army and the Tri-Services routinely experience an environment that is both hot and humid. This results in an ongoing and severely corrosive environment to which bare and often un-insulated steel piping is exposed
