High Strength: Ductile iron exhibits excellent tensile strength, making it suitable for high-pressure applications.
-
Flexibility: Unlike brittle cast iron, ductile iron can withstand significant deformation without cracking.
-
Corrosion Resistance: With appropriate coatings, ductile iron fittings resist corrosion, extending their service life.
-
Cost-Effective: The durability and longevity of ductile iron reduce maintenance and replacement costs over time.
1.3 Applications of Ductile Iron Tee Fittings
These fittings are widely used in:
-
Water Distribution Systems: Ensuring efficient flow and distribution.
