ABSTRACT

Coffee Break Training: Possible Product Incompatibility   [open pdf - 210KB]

"In many automatic sprinkler installations it is common for the fitter to use both steel and nonmetallic pipe. The steel's durability and the superior friction loss characteristics of plastic together make them a desirable combination in some fire protection applications. However, concerns have occurred recently regarding the use of some antimicrobial coatings found on some steel pipe. The coatings are provided to resist microbiologically influenced corrosion [MIC] (See Coffee Break Training 2008-20 for information on MIC). Research suggests that some of these coatings may contain compounds that can affect nonmetallic sprinkler pipe, resulting in environmental stress cracks."
