Fire sprinkler systems rely on high-quality materials to ensure efficiency, durability, and compliance with safety standards. The key components include pipes, sprinkler heads, valves, fittings, and water storage tanks.
Pipes
Pipes form the backbone of a fire sprinkler system, carrying water from the source to the sprinkler heads. Common materials include:
- CPVC (Chlorinated Polyvinyl Chloride): Lightweight, corrosion-resistant, and commonly used in residential and domestic systems.
- Steel: Galvanised or black steel pipes, ideal for high-pressure and commercial applications.
- Copper: Durable, heat-resistant, and used in specialist installations.
- PEX (Cross-linked Polyethylene): Flexible and resistant to scaling and corrosion, suited for certain residential applications.
Residential and Domestic Systems
Residential and domestic sprinkler systems predominantly use plastic CPVC pipes and fittings, installed by either solvent welding or fusion welding. Both methods are LPCB-certified for safety and reliability. Sprinklers Direct Ltd selects the best product for each installation or the material specified by the client.
Sprinkler Heads
Sprinkler heads release water when a fire is detected. Materials and mechanisms include:
- Brass, Bronze, or Stainless Steel: Corrosion-resistant and long-lasting.
- Glass Bulb Mechanism: Heat-sensitive liquid expands, breaking the glass and activating the sprinkler.
- Fusible Link Mechanism: Metal alloy melts under high temperatures, triggering water flow.
Types of sprinkler heads:
- Pendent Sprinklers: Direct water downward from the ceiling.
- Upright Sprinklers: Positioned upward, common in industrial settings.
- Sidewall Sprinklers: Mounted on walls for areas without ceiling access.
Valves and Fittings
Valves and fittings regulate water flow and maintain system integrity. Key components include:
- Control Valves: Brass or stainless steel, allowing manual operation and shutdown.
- Check Valves: Prevents backflow, ensuring proper water direction.
- Pressure Relief Valves: Protects the system from excessive pressure.
- Pipe Fittings: Includes elbows, tees, and couplings, made from brass, steel, or CPVC.
Water Storage Tanks
Water tanks ensure a reliable supply for fire sprinkler systems. Types include:
- Fibreglass Tanks: Lightweight and corrosion-resistant.
- Steel Tanks: Strong and durable, ideal for larger systems.
- Polyethylene Tanks: Cost-effective and widely used in residential installations.
- Concrete Tanks: Used for underground storage in large-scale applications.
