Why are there are so many failures of orange CPVC fire sprinkler pipes and fittings? The main reason is that CPVC is not compatible with most hydrocarbon chemicals and chemicals are everywhere. One of the chemical contaminants we frequently find on the inside of CPVC pipe are chemicals from the antimicrobial liming used inside of Allied ABF steel pipe. The chemicals absorb into high stress points and in cement residues inside joints. If you are concerned that you may be at risk because your fire sprinkler piping system contains both Allied ABF steel pipe in combination with CPVC, contact us and we will examine your piping system using endoscopy to determine if there is any evidence of chemical degradation of the pipe and fittings. The assessment is fast and is non-destructive.
