Flexible Fire Sprinkler Connections – Easy & Reliable Installation
Flexible Fire Sprinkler Connections – Complete Guide by Fortis Forge Introduction In fire protection systems, installation speed, adaptability, and reliability can make the difference between an efficient setup and a costly delay. Flexible fire sprinkler connections have become the industry standard for connecting branch lines to sprinkler heads, especially in commercial buildings, offices, and industrial facilities. At Fortis Forge, we manufacture and supply UL Listed and FM Approved flexible sprinkler hose assemblies designed for high performance, easy installation, and long service life. Our products comply with NFPA 13 and international safety standards, making them suitable for diverse applications where accuracy, speed, and durability are critical. 1. What Are Flexible Fire Sprinkler Connections? Flexible fire sprinkler connections are pre-assembled, bendable stainless steel hose assemblies used to connect the fire sprinkler head to the branch piping in a ceiling system. Key components: Flexible Hose: Corrugated stainless steel tube for easy positioning. Bracket System: Holds sprinkler head in place during installation. Reducer/Adapter: For connection to various sprinkler head sizes. Sealing Elements: Ensures leak-proof performance. 2. Why Use Flexible Fire Sprinkler Connections? a. Faster Installation Eliminates cutting and threading pipes on-site. b. Adjustability Easily bends to align with ceiling tiles and obstructions. c. Reduced Labor Costs Installers can finish more heads per day compared to rigid piping. d. Minimized Ceiling Disturbance No need for post-installation ceiling adjustments. e. Seismic Performance Absorbs building movement and vibrations during earthquakes. 3. Types of Flexible Fire Sprinkler Connections Standard Flexible Hose Assemblies – For general ceiling grid installations. Seismic-Approved Flexible Hoses – Enhanced movement absorption for seismic zones. Extended-Length Hoses – For ceilings with high clearance or unique layouts. High-Pressure Rated Flexible Hoses – Designed for special hazard applications. 4. Fortis Forge Flexible Hose Construction Hose Material: 304/316 stainless steel corrugated tube for corrosion resistance. Braid Layer: Stainless steel wire braid to prevent elongation under pressure. End Fittings: Carbon steel or stainless steel, precision machined. Brackets: Galvanized or stainless steel mounting kits. Seals: EPDM or PTFE for leak-proof connections. 5.
