Wet pipe fire suppression systems are the standard for most indoor spaces. These systems load a network of pipes and sprinkler heads with pressurized water, ready to activate when heat sensors in the sprinkler head are triggered. ASTM A795 describes the steel pipes used to create this network as being made from different “schedules” (wall thicknesses) of steel, all with the same requirements for chemical composition. The needs of a particular fire suppression system dictate the schedule of steel to be used. Steel sprinkler pipes can be galvanized at the customers request (at a price premium), but are typically provided with a “mill coating” of protective lacquer. Corrosion to the inside of pipes is of significant concern. Antimicrobial coatings aimed at slowing this corrosion are available from some of the largest pipe manufacturers in the US, so have been included as common in this review. While all schedules of steel have the same chemical composition, schedule 40 pipes are most common and have been used to calculate dimensions.
