Fire Sprinkler Pipe is a specialized category of steel pipe used to transport water or gas to suppress fires. Because these pipes spend most of their life sitting idle, they must be highly resistant to Microbiologically Influenced Corrosion (MIC), rust that happens from the inside out.
These pipes are typically galvanized or coated with specialized antimicrobial liners and must meet strict UL (Underwriters Laboratories) and FM (Factory Mutual) certifications.
