In the manufacture of cement pipes, we can know that the cement pipe is a preset pipe made of cement and steel bars. It can be used as a city sewage pipe and a water pipe used in some special factories and mines. Its manufacturing can be divided into a variety of processes. Today, Wanxin Xiaobian will introduce to us the centrifugal pipe manufacturing process of cement pipes, let's take a look!

Plastic concrete is used, and the wall structure of the pipe is layered after molding, which affects the load resistance of the concrete. The general designation of the concrete is C30, which can also be C40, but the emphasis of the concrete at the mouth of the pipe is lower than the pipe body. Pipe jacking; When the pipe mold is lying on the centrifuge at high speed during molding, the steel mesh moves with it, which will present two situations that affect the service life of the pipe:

1. When the welded joints of the reinforced mesh are not strong, the tendons will run out and leak out, which will make the pipe part appear non-reinforced.

2. It is difficult to center the reinforced mesh after forming. The reinforced mesh is eccentric, that is, the protective layer of the reinforced mesh is uneven; this process requires a large number of molds to ensure the output. The size of each mold has errors. Long-term disassembly and use will also show large deformation, which causes large errors in the roundness of the pipe, the verticality of the nozzle, the diameter of the pipe, and the length of the pipe, which affects the quality of the engineering equipment. Leakage will cause the road to sink Pollution of soil and groundwater on both sides of the pipeline.
