Fire protection pipelines cable trays and air ducts

Fire protection for pipelines, cable trays, and air ducts involves specialized wraps, coatings, and fire-rated ducts to prevent fire spread, maintain system functionality, and comply with safety standards.

Fire Protection for Air Ducts

Air ducts, including ventilation, smoke exhaust, and kitchen exhaust ducts, require fire-rated cladding to prevent fire and smoke from spreading through buildings. Fire protection ducts are classified based on fire resistance, such as L30/L90 for ventilation ducts, I30/I90 for installation ducts, and E30/E90 for electrical ducts, providing 30 to 90 minutes of protection depending on the system and building requirements. These ducts ensure that critical systems like emergency ventilation, fire alarms, and power supply remain operational during a fire, safeguarding people and property .

Fire Protection for Cable Trays

Cable trays carrying electrical or control cables are protected using fire-resistant wraps, coatings, and tapes. Products like FireMaster Cable Tray Wraps and FLAMMOTECT-A coatings form a high-temperature barrier that prevents ignition of combustible materials and maintains cable functionality during fires . Firestop caulks and intumescent materials, such as 3M Fire Barrier Moldable Putty+ or IC 15WB Caulk, seal penetrations and edges, blocking heat and smoke while allowing retrofitting in existing installations . Typical protection durations range from 30 minutes for hydrocarbon fires to longer periods depending on the system design .

Fire Protection for Pipelines

Pipelines, including combustible or multilayer pipes, are protected using fire-rated wraps, mineral fiber insulation, or coatings. These solutions prevent fire spread along the pipe route and protect surrounding structures. In mixed systems, pipelines may be installed in fire-rated false ceilings or smoke-proof filter rooms, ensuring compliance with standards like UNI EN 12101:13:2022 . Fire protection for pipelines is essential in industrial plants, hospitals, and high-rise buildings to maintain safety and operational continuity.

Key Considerations

• Material Selection: Use fire-resistant wraps, coatings, or ducts tested to international standards.
• Fire Resistance Rating: Choose products based on required protection time (e.g., 30, 60, 90 minutes).
• Installation Compliance: Follow building codes and fire safety regulations for proper sealing, spacing, and support.
• Environmental Resistance: Some coatings also protect against UV, moisture, chemicals, and saltwater exposure .
• Maintenance and Inspection: Regular checks ensure that fire protection systems remain effective and intact. By implementing these fire protection measures, buildings and industrial facilities can limit fire spread, protect critical infrastructure, and ensure safe evacuation routes while maintaining operational systems during emergencies .
