The production of reinforced concrete drainage pipes involves placing a steel reinforcement cage into a mold, and forming a type of reinforced concrete pipe by liquefying and compacting concrete through high-frequency vibration of the core mold or compacting concrete via suspended roller vibration and rolling.
Reinforced Concrete Drainage Pipe with Flexible Socket and Spigot Joint (RCP)
Reinforced concrete drainage pipes with socket and spigot in sizes DN300~DN1200 are manufactured by the suspended roller process, while those in DN1350~DN1650 are produced by the core mold vibration process. These are flexible joint pipes sealed with wedge-shaped rubber gaskets.
Pipe Properties
The product is made of stiff concrete, featuring high concrete strength and strong load-bearing capacity.
Complete product specifications with flexible joints enable quick construction and easy installation.
The joints are sealed with wedge-shaped sliding rubber gaskets, providing excellent sealing performance, convenient pressure testing, strong adaptability to foundations, and high seismic resistance.
Application Scope
Widely used for rainwater and sewage drainage in urban areas, factories, residential communities, as well as gravity-flow channels and open-trench pipeline construction projects for farmland irrigation.

Reinforced Concrete Jacking Pipes Series (DRCP)
Reinforced concrete drainage pipes for jacking construction are produced with advanced core-mold vibration equipment introduced from Germany and top domestic facilities. They are flexible joint pipes sealed with wedge-shaped or toothed rubber gaskets.
Pipe Performance
Manufactured with dry-hard concrete, the product features high concrete strength, excellent compactness, good impermeability and strong compressive load-bearing capacity.
With complete specifications and flexible joints, the pipes are convenient for construction and installation, suitable for trenchless underground pipeline laying.
The joints are sealed with wedge-shaped sliding rubber gaskets, providing excellent sealing performance, reliable construction, high end pressure and long jacking distance.
Application Scope
Widely used in rainwater and sewage drainage pipelines, water diversion and farmland irrigation projects, highway and railway culverts, and channel culverts constructed by trenchless (or trenching) method. They can also be applied to casing projects for electric power, thermal energy, gas, petroleum, communication and other utilities.

Double-Gasket Steel Socket Reinforced Concrete Jacking Pipe
This double-gasket steel socket-and-spigot jacking pipe is manufactured with advanced core-mold vibration equipment introduced from Germany and top-tier domestic facilities. It is a flexible joint pipe sealed with O?shape rubber gaskets.
Pipe Performance
Formed by core-mold vibration technology, the pipe features high concrete strength and excellent compactness.
The pipe joint adopts a specially designed steel socket-and-spigot with double O?shape rubber gaskets, providing outstanding sealing performance.
The inner and outer surfaces of the steel socket and spigot are protected by concrete, which slows down corrosion in confined working conditions and extends the service life of the pipe.
It can well adapt to foundation deformation and effectively prevent joint leakage caused by foundation settlement or earthquakes.
The pipe ends allow high jacking force, enabling long?distance jacking construction, reducing project cost and improving economic efficiency.
Application Scope
Mainly used for trenchless (also open-trench) construction projects with high sealing requirements and long service life, especially suitable for complex geological conditions and special engineering fields.Applications include: rainwater and sewage projects, casing projects crossing highways, railways and buildings, as well as utility tunnel projects for electric power, thermal energy, communication, gas, water supply and other industries.
