Product Features
Premium ductile iron material toughness: Adopts high-purity ductile iron raw materials with excellent tensile strength and impact resistance, effectively avoiding cracking and deformation under high pressure and buried underground complex environments, far more durable than traditional cast iron tee fittings.
Zero-leakage sealing performance: Precision one-piece casting molding with smooth and flat interface size, matching perfectly with standard ductile iron pipes. Equipped with high-elastic sealing structure to ensure tight connection, completely prevent medium leakage in water delivery and drainage pipelines.
Multi-scene anti-corrosion protection: Supports multiple surface anti-corrosion treatments including food-grade epoxy coating and thickened bitumen coating, resisting oxidation, acid and alkali corrosion, and soil erosion, adapting to harsh underground, humid and chemical contact working environments.
Application
Municipal tap water supply pipeline network reconstruction and new construction projects
Urban sewage discharge and rainwater drainage pipeline systems
Industrial factory water supply, circulating water and wastewater discharge pipelines
Water conservancy project water delivery and diversion supporting facilities
Residential community, commercial building pipeline supporting engineering
Road and bridge buried pipeline supporting projects
Materials
Main Body: High-grade ductile iron, compliant with ASTM A536 / EN GJS-450 standard, with high toughness and pressure resistance
Anti-corrosion Coating: Food-grade epoxy resin / modified bitumen / cement mortar lining, non-toxic and environmentally friendly
Sealing Accessories: High-elastic rubber seal, wear-resistant and aging-resistant
