What type of sprinkler systems utilizes pipes and specialized techniques for water delivery?

Dry pipe systems are a specific type of sprinkler system designed to prevent freezing in environments where temperatures can drop below the freezing point. These systems utilize pipes filled with air or nitrogen under pressure, which keeps the water supply contained within a remotely located source, typically a water tank or reservoir.

When a fire occurs, the heat causes a specially designed sprinkler head to activate, resulting in the pressure in the pipes dropping. This drop allows the dry pipe valves to open, permitting water to flow through the pipes and out of the activated sprinklers onto the fire. This method of water delivery is particularly effective in high-rise buildings, unheated areas, or locations where freezing might compromise the system.

The advantages of dry pipe systems include their ability to remain functional in conditions where traditional wet pipe systems might fail due to ice formation. By employing specialized techniques for pressurization and valve operation, dry pipe systems ensure the effective delivery of water only when needed, enhancing the overall fire safety within high-rises.
