They are widely used in fire protection, water supply/drainage, HVAC, and industrial piping systems. Key FeaturesHigh Strength & Corrosion ResistanceDuctile iron offers higher tensile strength and better corrosion resistance compared to standard cast iron (typically coated with zinc or epoxy).Quick InstallationUses grooved mechanical joints-no welding or threading required, saving time and labor costs.Seismic & Movement ToleranceFlexible connections absorb vibrations and minor displacements, making them ideal for earthquake-prone areas.Excellent SealingRubber gaskets (EPDM/NBR) ensure leak-proof performance, even under high pressure.Easy Maintenance & DisassemblyNo pipe cutting needed, simplifying system modifications or repairs. Common StandardsInternational 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.
