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 function. The interface can be deflected to adapt to a certain foundation settlement and achieve long-distance steering installation.

The sealing principle of the GT type interface of GT type ductile iron pipe is similar to that of the T type interface. As the internal pressure of the pipeline increases, the tighter the contact surface between the rubber ring sealing sleeve and the socket, the better the sealing effect.

The self-anchored ductile iron 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.

The emergence of horizontal drill rod technology avoids road excavation and damage to other underground pipelines, reducing users' trenchless costs. At the same time, underground pipelines have less impact on traffic and the environment. In addition, it can run underground. In recent years, it has been widely used in the construction of underground pipelines such as municipal, industrial, and electric power. Horizontal drill rods are suitable for medium and small diameter ductile iron pipes.

The main application area is the municipal sewage pressure pipe network with high anti-corrosion requirements. Sewage treatment plants have certain requirements for pressure resistance, and the medium contains polyphenols and cyanide, which are corrosive substances that may harm the industrial sewage pipe network system.

A Double Eccentric Flange Butterfly Valve is a high-performance industrial valve characterized by its dual-offset design of the stem axis. The first offset positions the stem axis away from the centerline of the disc sealing surface, significantly reducing friction during opening/closing. The second offset places the stem axis away from the pipeline/valve body centerline, enabling progressive linear contact sealing between the disc and seat when closed. This structure dramatically enhances sealing reliability and service life, making it suitable for demanding conditions involving medium-to-high pressure, high temperature, and corrosive media.
