The self-anchored pipe adopts a special mechanical design to weld the ring to the socket end to achieve reliable anchoring performance, while retaining the flexibility of the joint, with good flexural performance, which can replace the function of the constraint block and realize the design without constraint blocks. It is mainly used in situations where space, time or economic conditions are not suitable for setting restrictive blockades; there is a certain foundation settlement, or the slope of the pipeline laid on the ground exceeds 20% or the slope of the underground pipeline exceeds 25%. The axial stress at the end of the sleeve is transmitted to the sleeve through the sleeve retaining ring, flange, bolts, etc., thereby realizing the transmission of axial stress and making the interface have

The GT type interface is shown in the figure below. Its sealing principle is similar to that of the T type. As the internal pressure of the pipeline increases, the closer the contact surface between the rubber ring sealing cover and the socket is, the better the sealing effect. Standard: ISO2531, EN545, EN598 Category: K, C Type Joint type: GT type Joint range: DN80-DN2600 Length: 8.15 meters, 6.0 meters, 5.7 meters, can be customized according to customer requirements Application: drainage of water supply projects, sewage irrigation, water pipelines, etc. Internal coating: Portland cement mortar lining; sulfate-resistant cement mortar lining; high-alumina cement mortar; fused epoxy coating; polyurethane lining

The T-joint has a simple structure, is easy to install, and has good sealing performance. The contact pressure generated by the compression deformation of the rubber ring acts as a self-sealing, and the hard rubber part of the rubber ring acts as a fixed centering. The interface can achieve deflection, adapt to a certain foundation settlement, and achieve long-distance steering installation. Standard: ISO2531, EN545, EN598 Category: Class K, Class C Joint type: T-joint Range: DN80-DN2600 Length: 8.15 meters, 6.0 meters, 5.7 meters, can be customized according to customer requirements Application: drainage of water supply projects, sewage irrigation, water pipelines, etc. Internal coating: Portland cement mortar lining;
