KEY WORDS：Fire protection grooved 45° elbow、Grooved equal-diameter elbow for fire systems、Ductile iron grooved elbow、22.5° fire elbow、Red epoxy coated grooved elbow、Weld-free grooved clamp elbow、Quick-install fire protection elbow、Seismic grooved piping elbow、Commercial fire piping grooved elbow
Product Features
1.Priecise Flow Direcise:22.5° gentle angle design minimizes fluid resistance for smooth fire water/domestic water circulation, reducing pressure loss and ensuring efficient system operation.
2.Robust & Corrosion-Resistant:Crafted from high-grade ductile iron with red epoxy coating (fire protection-specific), offering excellent tensile strength, impact resistance, and long-term corrosion protection in harsh environments (coastal, industrial areas).
3.Weld-Free Quick Installation:Grooved clamp connection eliminates welding, cutting on-site labor time by 50%. Tool-free assembly reduces safety hazards (no weld slag/high temperature) and allows easy disassembly for maintenance.
4.Superior Sealing & Pressure Resistance:Equipped with high-performance rubber gaskets (service life up to 70 years) for leak-proof sealing. Rated for 1.6–2.5MPa nominal pressure, passing 4x hydrostatic testing to ensure reliability in fire emergencies.
5.Strong System Adaptability:Flexible connection absorbs vibration and thermal expansion, enhancing seismic performance. Compatible with DN65–DN150 sizes, compliant with GB 5135.11/CJ/T 152-2016 standards, and suitable for commercial/industrial/residential fire protection piping networks.
6.Certified Quality Assurance:CCCF, UL, and FM certified (optional). 100% factory inspection (dimensional accuracy, coating adhesion, pressure resistance) ensures compliance with global fire safety regulations and project acceptance requirements.
