Sprinkler & Foam Systems

Sprinkler

Fireline can design, furnish and install all types of fire sprinkler systems including wet pipe systems, pre-action systems and deluge systems as well as standpipe systems and fire pumps.

• Wet Pipe Sprinkler Systems - The most common type of sprinkler system. A sprinkler system employing automatic sprinklers attached to a piping system containing water. This piping system is connected to a water supply so that water discharges immediately from sprinklers opened by heat from a fire.
• Dry Pipe Sprinkler Systems - A sprinkler system employing automatic sprinklers that are attached to a piping system containing air or nitrogen under pressure. The release of the air or nitrogen permits the water pressure to open a dry pipe valve, allowing the water to then flow into the piping system and out through the opened sprinklers.
• Pre-Action Systems - A sprinkler system employing closed sprinklers attached to a piping system that is connected to a water supply through a valve that is opened by the operation of a fire detection system installed in the same areas as the sprinklers. When this valve opens, water flows into the piping system and discharges out through the open sprinklers.
• Deluge Sprinkler System - A sprinkler system employing open sprinklers attached to a piping system that is connected to a water supply through a valve that is opened by the operation of a fire detection system installed in the same areas as the sprinklers. When this valve opens, water flows into the piping system and discharges from all sprinklers attached thereto.

Foams

Foams provide the most effective means to extinguish and secure flammable liquid fires. Loading racks, tank farms, aircraft hangars and flammable liquid processing plants are protected with foam systems furnished and maintained by Fireline.

Foam-Water Sprinkler System

A special sprinkler system that is pipe-connected to a source of foam concentrate and to a water supply. The foam-water sprinkler system is equipped with appropriate discharge devices for extinguishing agent discharge and for distribution over the area to be protected. The piping system is connected to the water supply through a control valve that usually is actuated by operation of automatic fire detection equipment that is installed in the same areas as the sprinklers. When this valve opens, water flows into the piping system, foam concentrate is injected into the water, and the resulting foam solution discharging through the discharge devices generates and distributes foam. Upon exhaustion of the foam concentrate supply, water discharge follows and continues until shut off manually. Foam-water sprinkler systems can be used for discharge of water first, followed by discharge of foam for a specified period, and then followed by water until manually shut off. Existing deluge sprinkler systems that have been converted to the use of aqueous film-forming foam or film-forming fluoroprotein foam are classified as foam-water sprinkler systems.
