A DI (Ductile Iron) Strap Saddle is a type of pipe fitting used to create a secure connection to an existing pipeline, typically for water, gas, or sewage systems. It is made of ductile iron, a strong and durable material known for its high tensile strength, excellent corrosion resistance, and ability to withstand high-pressure conditions. The strap saddle design allows it to be clamped around a pipe, providing a stable and leak-free connection for service lines or other pipeline connections.

1. Material: Ductile Iron (DI)

   • Ductile iron is a type of cast iron with added alloys that improve its strength, toughness, and flexibility. It is highly resistant to corrosion, making it ideal for use in water and wastewater systems, especially in harsh environments.

2. Strap Design:

   • The strap part of the saddle refers to a metal band or strap that wraps around the circumference of the pipeline. This design helps secure the saddle firmly in place, providing a tight and stable connection.

3. Bolts and Clamps:

   • The saddle is equipped with bolts and clamps that are used to tighten the strap around the pipe. These fasteners ensure a strong, leak-free connection by compressing the saddle onto the pipe and creating a secure fit.

4. Tapping Port:

   • The tapping port (outlet) is a threaded or unthreaded hole in the saddle where a branch connection (like a smaller pipe or valve) can be attached. The tapping port is where the service line is connected, and it is typically drilled during installation.

5. Sealing Mechanism:

   • The DI strap saddle often includes a gasket or O-ring for sealing. This gasket ensures a watertight or airtight seal, preventing leaks between the saddle and the pipe, even under pressure.

6. Corrosion Protection:

   • Coatings like epoxy or bituminous paint are often applied to the ductile iron to enhance its resistance to corrosion, especially in outdoor or underground applications.

• Strength and Durability: Ductile iron provides high strength, which ensures the saddle can withstand the internal pressures of pipelines, making it suitable for both high-pressure and large-diameter pipelines.
• Corrosion Resistance: The material's resistance to corrosion makes it ideal for use in water, sewage, or other environments where the saddle will be exposed to moisture, chemicals, or harsh conditions.
• Ease of Installation: Strap saddles can be installed quickly without cutting or disturbing the main pipeline. The saddle simply wraps around the pipe and is secured with bolts, making it a faster and easier option compared to welding or cutting.
• Leak-Free Connection: The combination of the tight strap and the sealing gasket ensures a leak-free connection, which is crucial for preventing water or fluid loss in critical systems.
• Versatility: DI strap saddles are available in different sizes to fit various pipe diameters and can be used in a wide range of industries, including water distribution, gas pipelines, sewage systems, and irrigation.
