T-Type Joint Ductile Iron Pipe

The push-on joint T-type ductile iron pipe is a type of pipe used for various applications, particularly in water supply and sewer systems. It is known for its durability, strength, and ease of installation.

Sealing principle Structure of T-type joint

During joint installation, the external spigot is extruded on the rubber ring inside the socket. The compression deformation can generate a certain degree of contact pressure. And it is the so-called self-sealing action of the rubber ring that keeps the joint tight. The self sealing effect means, when the rubber ring is under the fluid pressure, the actual contact pressure on the rubber ring is the sum of the contact pressure of the pre-compressed rubber ring and the new contact pressure on the rubber ring brought by the fluid pressure. Since the contact pressure is higher than the fluid pressure, so that the joint is well tightened.

Joint Features:

The joint features simple structure, easy installation and sound sealing performance. The positioning of sealing ring and deflection of joint are taken into consideration during socket structure design. By controlling the insertion depth of the spigot, the joint can have certain axial flexibility. Therefore this type of joint is able to adapt to certain foundation settlement, while long-distance deflection of pipeline can be achieved through its deflection angle,  

The rubber ring consists of two parts, the hard rubber and soft rubber. The hard rubber can support and align the pipe joints, and greater thrust is needed during installation. T-type Joint is unable to prevent pipe slippage, therefore the concrete blocks to resist the axial forces should be set at the bend of pipeline, or certain length of self-anchored joint ductile iron pipe should be laid.

Application Field: 

Water supply (potable water, sewage, etc.) pipeline; Underground/overground laying, and the pipe laying slope does not exceed 20% (overground laying) or 25% (underground laying).

Features

Ductile Iron Material: The pipe is made from ductile iron, a type of cast iron that has been treated to enhance its properties. Ductile iron is more flexible and resilient than traditional cast iron, making it less prone to cracking and breaking under pressure.

T-Type Design: The pipe has a T-shaped configuration, which is useful for connecting to other pipes or fittings at right angles. This design is common in pipeline systems when branching off or redirecting the flow.

Push-On Joint: The push-on joint is a simple and efficient way of connecting pipes. It involves inserting one pipe into another with a rubber gasket seal between them. The gasket provides a tight and secure seal, preventing leaks and ensuring a reliable connection.

No Need for Additional Equipment: One of the significant advantages of the push-on joint is that it doesn't require special tools or equipment to assemble. It simplifies the installation process and reduces labor costs.

Corrosion Resistance: Ductile iron pipes are known for their resistance to corrosion, which ensures a longer lifespan and less maintenance over time, even when used in challenging environmental conditions.

Pressure and Load Capacity: T-type ductile iron pipes can handle high pressures and heavy loads, making them suitable for various applications, including water distribution, sewage transport, and industrial uses.

Wide Range of Sizes: These pipes come in various sizes, allowing flexibility in designing and constructing pipeline systems to meet specific requirements.
