Internal pipe inspection is critical for maintaining the reliability of a dry pipe sprinkler system because these systems are particularly susceptible to corrosion and obstruction, which can significantly impair their ability to function effectively during a fire. Dry pipe systems contain pressurized air or nitrogen instead of water. When a sprinkler head activates, the air pressure is released, allowing the dry pipe valve to open and water to flow into the piping. However, the presence of air and moisture within the pipes creates a corrosive ....
