Centrifugal cement pipe making machines are a type of cement pipe manufacturing machinery, playing a crucial role in the production of cement pipes for highway construction. These machines enable rapid molding using factory-scale production processes and steam curing. Proper operation is essential. Furthermore, the molding process for cement pipes must be carefully controlled.

After concrete is poured into the cement pipe mold using a centrifugal cement pipe making machine, the concrete mixture is evenly distributed along the pipe wall until it compacts. The forming principle can be divided into four stages:

1. Pouring and Distributing Stage: This stage mainly involves pouring the mixed concrete into the slowly rotating steel mold;

2. Even Distribution Stage: The mixture is evenly distributed along the inner wall of the steel mold using the centrifugal force gained from rotation;

3. Medium-Speed Stage: This is the intermediate stage transitioning from slow to fast speed;

4. Compacting Stage: In this stage, the steel mold rotates rapidly, giving the concrete within the mold a predetermined centrifugal force, thus compacting the concrete.

When using a centrifugal cement pipe making machine, each stage at different speeds has an optimal centrifugal duration. Strictly controlling the speed and duration of each stage is crucial to ensuring the quality of precast products.
