Its products are divided into concrete drainage pipes and reinforced concrete drainage pipes according to the presence or absence of steel bars, and are divided into flexible interface pipes and rigid interface pipes according to the connection method. Various types of products of cement pipes have reached the quality technical requirements.
It is required that the concrete strength level should not be lower than C30; the inside and outside of the pipe should be flat, the pipe should be free of sticky skin, pitted surface, honeycomb, slump, leaking ribs, hollow drums; cracks on concrete pipes are not allowed, and the appearance of reinforced concrete pipes is not allowed There are cracks, the width of the internal and external cracks must not exceed 0.05mm, and the joints should not leak.

泥管 Prestressed cement pipe 自应力水泥管的差异? And the difference between self-stressed cement pipe?

Pre-stressing is to moderately stretch the steel reinforcement in the concrete before the concrete sets. After the concrete is removed, the external force will be removed, and the steel will cause a shortened stress in the concrete, making the reinforced concrete stronger and less likely to crack. Self-stressed cement pipes are made of special cement and are mainly used in self-stressed reinforced (steel wire mesh) concrete (mortar) pressure pipes. The same components are not prone to cracks. The difference between the two is that the former uses a single steel bar and ordinary cement, and the latter uses steel wire mesh and special cement.

Parameters of cement drainage pipe
Cement pipe is widely used in our daily life. It has two other names, cement pressure pipe and reinforced concrete pipe. It is generally used for sewage drainage and other effects in urban construction; its manufacturing processes are generally divided into three methods: centrifugal tube, suspension tube tube, and core mold oscillation.
The life of the cement pipe will affect the following factors:
1. Reinforcement nets will have tendons running and leaking in real time if there are no welding points, which will make the tube part appear non-reinforced.
2. It is difficult to center the reinforcing mesh after forming, and the reinforcing mesh is a pain, that is, the protective layer of the reinforcing mesh is uneven.
