According to the forming principle, the pipe manufacturing process mainly comprises the following steps: the method comprises a centrifugal forming process, a suspension roller forming process, a vertical vibration forming process, a core mold vibration forming process and a radial extrusion forming process. Currently, the core mold vibration molding process and the radial extrusion molding process become mainstream of the RPC production process due to the advantages of high production efficiency, low energy consumption, good internal quality and the like of the molding process. The radial extrusion forming process is generally used for producing pipelines below DN1200, and the core mold vibration forming process is generally used for producing pipelines above DN1000, which is the mainstream of RCP.

However, the core mould vibration forming process adopts the dry and hard concrete, and the wet concrete can be demoulded immediately after the forming is finished, so that the pipeline outer wall of the core mould vibration forming process is rough and is not accepted by the market, so that the finishing treatment is needed.
