Product Features: Ductile Iron Double Socket Tee with Flange Branch
Superior Material Strength: Manufactured from high-strength Ductile Cast Iron (Grades GGG-40 or GGG-50), this fitting offers superior mechanical properties compared to grey cast iron. It exhibits high tensile strength, excellent ductility, and remarkable impact resistance, allowing it to withstand high internal pressures, heavy traffic loads, and ground movement without fracturing.
Robust Jointing System (Double Socket): The two female sockets (bells) are designed for quick and secure push-in joints. They accommodate standard ductile iron pipes and typically feature integrated gasket grooves. When fitted with the appropriate EPDM or NBR rubber gaskets, these joints provide a flexible, water-tight, and pressure-resistant seal that simplifies installation and accommodates minor angular deflection.
Versatile Flange Branch (Flanged Outlet): The integral flange on the branch outlet provides a rigid, bolted connection point. This is ideal for connecting to valves (gate valves, butterfly valves), pumps, hydrants, or flanged pipework. The flange is typically drilled to international standards (such as ISO 7005-2, EN 1092-2, or BS 4504), ensuring compatibility with a wide range of mating components.
Corrosion Resistance: To ensure a long service life in aggressive soil and water environments, the fitting is protected by a robust external coating. Standard finishes include a bitumen coating or a high-performance zinc-rich base layer plus a blue or black epoxy topcoat. The internal surfaces are usually lined with a smooth cement mortar lining (as per ISO 4179) to prevent tuberculation, maintain water quality, and ensure long-term flow efficiency.
Hydraulic Efficiency & Reliability: The smooth internal bore and consistent wall thickness minimize friction losses, ensuring optimal flow rates. The fitting is designed and tested to withstand high operating pressures (such as PN10, PN16, or PN25), guaranteeing a reliable, maintenance-free connection in critical water transmission, sewerage, and fire-fighting pipelines
1. Water Distribution Networks: This fitting is extensively used in municipal potable water pipelines. The double sockets allow for the continuation of the main water transmission line, while the flanged branch outlet serves as the ideal connection point for isolation valves, control valves, or hydrants. It is essential for creating branching points in underground water mains where future maintenance access or flow control is required.
2. Fire Fighting Systems: In fire suppression infrastructure, this tee is critical for connecting fire hydrants to the primary water main. The flanged outlet provides a secure, bolted attachment for the hydrant's base, ensuring a reliable high-pressure water supply. It is commonly installed along roadsides and in industrial areas to meet stringent fire safety regulations.
3. Sewerage and Wastewater Systems: Thanks to its corrosion-resistant linings and seals, the fitting is suitable for both gravity and low-pressure sewer lines. It facilitates the connection of branch sewers to the main trunk line. The flexible socket joints accommodate ground settlement, while the flanged branch can be used for future tie-ins or for connecting to pumping station equipment.
4. Industrial Process Piping: In industrial applications, this fitting is used to convey raw water, cooling water, or treated effluents. The flanged branch allows for the easy integration of flow meters, pressure gauges, or bypass lines. The robust nature of ductile iron makes it ideal for handling the vibration and pressure surges common in plant environments.
5. Irrigation Schemes: For large-scale agricultural irrigation projects, these fittings are employed to divert water from primary canals or pipelines into secondary distribution systems. The flanged outlet provides a convenient point for installing pumps or large-diameter valves that regulate water flow to specific crop zones.
Our Ductile Iron Double Socket Tee with Flange Branch is a high-performance pipe fitting engineered for reliability and durability in modern fluid handling systems. Designed to meet rigorous international standards, this fitting is the ideal solution for creating secure branch connections in water transmission, sewage systems, industrial piping, and firefighting networks.
Manufactured from high-strength Ductile Iron (Grade GGG-50 or equivalent), this component offers superior mechanical properties compared to traditional cast iron. It exhibits excellent tensile strength, yield strength, and impact resistance, ensuring long-term performance even under high operating pressures, heavy traffic loads, and challenging soil conditions.
Key Features and Design:
Double Socket Ends: The two main run ends feature deep bell sockets designed to accommodate standard Ductile Iron pipes. These sockets house a gasket groove that, when combined with a standard push-on rubber gasket (e.g., RJS or TYTON type), creates a quick, water-tight, and flexible joint. This push-fit design allows for easy installation, angular deflection to accommodate ground movement, and stress relief along the pipeline.
Flange Branch: The integral branch outlet is manufactured to international flange drilling standards (such as ISO 7005-2, EN 1092-2, or ASME/ANSI 125/150). This allows for a direct, bolted connection to valves, pumps, hydrants, or other flanged equipment. The flange face is machined to a smooth finish to ensure a secure seal with a gasket.
Corrosion Protection: To ensure a long service life, the fitting is protected by a robust external coating. Standard options include a zinc-rich paint base coat followed by a bitumen or epoxy top coat, providing a barrier against soil-side corrosion. For internal protection, a high-quality cement mortar lining (in accordance with ISO 4179) is applied to prevent tuberculation, maintain water quality, and ensure consistent flow characteristics.
Versatility: Available in a wide range of diameters (typically from DN 80mm to DN 1200mm) and pressure classes (PN 10, PN 16, PN 25, and PN 40), this tee can be customized to meet the specific hydraulic and operational demands of your project.
Choose our Ductile Iron Double Socket Tee with Flange Branch for a robust, leak-free, and efficient piping network that delivers exceptional value over its entire lifecycle.
