The purpose of the 5-year internal pipe inspection is to inspect for the presence of foreign organic and inorganic material. While performing the inspection if any Tubercles or Slime the pipe should be sent out and tested for M.I.C or Microbiologically Influenced Corrosion. While performing the inspection if a sufficient amount of Foreign Organic or Inorganic material is found an obstruction investigation SHALL be performed. It does not take much foreign material to clog or block a fire sprinkler head and prevent it from proper activation. Clogged or blocked piping could also prevent water delivery to a properly functioning fire sprinkler head preventing the ability for the fire sprinkler head to perform as designed.
Common areas for internal sprinkler corrosion are but not limited to:
- Riser Manifolds
- Dry Pipe Valves
- Improperly Pitched
- Dry Piping
- Main Incoming Piping
Signs of Internal Pipe Corrosion:
- Multiple Pinhole leaks on a fire sprinkler system
- Reduction in trip time on a dry system
- Obvious reduction in water flow rate from the inspector’s test or drain connection from previous inspections.
