DI (Ductile Iron) Tee is a T-shaped pipe fitting used to create a three-way junction (branching or splitting) in pipelines, primarily for water supply, sewage, and fire fighting systems. Made from ductile iron, these fittings offer high strength, durability, and corrosion resistance. They are commonly found in diameters ranging from 80mm to 1000mm and often feature flanged or mechanical joints.

• Purpose: Used to connect three pipes, allowing for the flow of media to be combined or separated.
• Material: Composed of ductile iron (carbon, silicon, manganese, iron, and alloys), which provides high impact resistance and structural strength.
• Types: Available as all-flanged tees, reducing tees (to change pipe diameter at the junction), or mechanical joint tees.
• Applications: Extensively used in water mains, sewage systems, and industrial applications due to their robustness and long service life.
• Standards: Often manufactured to standards like ISO 2531, EN 545 (water), EN 598 (sewerage), and AWWA C110.
• Coatings: Typically protected with coatings like FBE (Fusion Bonded Epoxy), bitumen, or cement lining to prevent corrosion.
