The Effects of Minor Constituents in Calcium Silicate Insulation on the Corrosion of Underground Heat Distribution Systems.

Abstract

This report presents the results of an investigation of the harmful corrosive effects of minor constituents in calcium silicate insulation on prefabricated steel conduit underground heat distribution systems. The research showed that the leachable chloride concentrations of commercially available calcium silicate insulation can contribute greatly to the corrosion of underground heat distribution systems and that the corrosion is aggravated if leaks in the system continue for long periods of time. Corrective measures are recommended to minimize this type of corrosion. (Author)
