I. Basic Definitions

Cement Pipe Socket: The socket refers to the design of the connection ends on both sides of the cement pipe, where one end features a socket and the other end has a spigot. This design facilitates the connection and sealing between pipes.

Cement Pipe Couplings: The coupling design is a unique method of connection, characterized by the presence of a certain slope or special shape at both ends of the pipe, allowing for interlocking during assembly and achieving a good sealing effect. This design enhances the stability and sealing integrity of the pipe.

Section II: Structural Features

The design of the cement pipe spigot focuses on the smoothness and alignment of connections, with a relatively simple and clear structure. The connection between spigots is achieved by filling the gaps with sealing materials, ensuring watertightness. In contrast, the design of the cement pipe bell mouth is more complex, utilizing special shapes at both ends of the pipe to interlock, creating a good mechanical locking effect, thereby enhancing the pipe's rigidity and stability.
