Reinforced Concrete Cylinder Pipe (abbreviated as RCCP) adopts a structure consisting of inner reinforced concrete layer, middle thick steel cylinder, and outer reinforced concrete layer. The pipe joint adopts a steel spigot-and-socket joint.

Specifications & Models

Product Features

1. High Safety Performance

   RCCP is a composite structure made of cold-rolled or hot-rolled deformed steel bars, steel cylinder and concrete. Low-carbon steel is used for reinforcement and steel cylinder, with integrally poured molding, providing high safety performance.
2. Excellent Durability

   Except for the spigot and socket, the entire pipe body is encased in concrete, resulting in strong corrosion resistance. The durability of the pipeline is greatly improved, with a service life of more than 50 years.
3. Strong External Load Resistance

   RCCP has high pipe stiffness and can bear large earth covering loads, with a cover depth of more than 10 meters.
4. Good Sealing Performance & Easy Installation

   RCCP adopts steel spigot-and-socket joints with excellent sealing performance. Each joint can be pressure-tested individually, enabling fast and convenient installation.
5. Strong Laying Environment Adaptability & Wide Application

   As a rigid pipe, RCCP has strong adaptability to foundation conditions. It can be installed by both open-cut and jacking methods, and can be used either buried or above ground.
