Ductile Iron Grooved Fittings are pipe connectors made of ductile iron, designed for quick installation using grooves and couplings. They are widely used in fire protection, water supply/drainage, HVAC, and industrial piping systems.
High Strength & Corrosion Resistance
Ductile iron offers higher tensile strength and better corrosion resistance compared to standard cast iron (typically coated with zinc or epoxy).
Quick Installation
Uses grooved mechanical joints-no welding or threading required, saving time and labor costs.
Seismic & Movement Tolerance
Flexible connections absorb vibrations and minor displacements, making them ideal for earthquake-prone areas.
Excellent Sealing
Rubber gaskets (EPDM/NBR) ensure leak-proof performance, even under high pressure.
Easy Maintenance & Disassembly
No pipe cutting needed, simplifying system modifications or repairs.
International Standards:
ASTM A536 (Ductile Iron Material)
AWWA C606 (Grooved Joints)
UL/FM (Fire Safety Certifications)
Chinese Standards:
GB/T 13295 (Ductile Iron Pipes for Water/Gas)
CJ/T 156 (Grooved Pipe Couplings)
Ductile Iron Grooved Fittings are widely adopted in fire protection, plumbing, HVAC, and industrial systems due to their high strength, rapid installation, and vibration resistance. They are particularly suited for projects requiring efficiency, reliability, and long-term durability.
