Reinforced concrete drainage pipes, commonly known as cement pipes, are those with steel rebar inside, hence the name. They are primarily used in drainage systems. The specifications include the inner diameter (DO) ranging from 100mm to 3000mm and the length (LO) from 1m to 20m.
Pressure Index: Level I, Level II, Level III; Bore Types: Flat End, Socket End, Spigot End, Double Socket End, Steel Socket End.

Reinforced concrete drainage pipe joints are a crucial component in drainage projects, as their quality determines the type of project and consequently affects the operation of the drainage system.

The advantages of reinforced concrete drainage pipes include low construction costs, short construction periods, and excellent impermeability. They are also convenient to use. Currently, reinforced concrete drainage pipes are widely used in public facility drainage systems, serving as a lining that is fixed and embedded within the inner wall of the pipes.
