The common problem of cement pipe is erosion. The erosion problem of cement pipe mainly includes crevice corrosion and corrosion. These two erosion methods belong to diffuse erosion and are not easy to be detected by inspectors. The other kind of intergranular corrosion cracking is the pipeline cracking caused by erosion and other external effects of support force and ground stress, causing huge damage. At this time, the pipeline shall be removed and replaced in time. There is also a common problem of mechanical equipment damage. This kind of damage mainly includes chisels and pits containing chisels, which is generally caused by mechanical equipment damage. External cracks are also a problem of cement pipes. These problems belong to the plan problem and can be easily detected. Peeling is a relatively serious damage condition, and perforation will lead to fracture or leakage.

Reinforced concrete cement pipes are very common in our daily life. The common places are urban underground sewage pipes and farmland irrigation pipes, which have gradually become indispensable products for urban development. However, the price of reinforced concrete cement pipes is not always the same. Many factors have a certain impact on the price of cement pipes, so why does the price fluctuate, What are the specific factors? Next, the manufacturer of Pinghu Huafeng cement pipe will explain the factors that affect the price fluctuation of reinforced concrete cement pipe.

The cause of cracks on the surface of cement pipe. The cracks on the surface of cement pipe are mostly caused by folding, and the key can be divided into two categories: one is caused by the evaporation and hardening of the water on the surface of cement pipe during rigid concrete pouring. Generally, the average external temperature of cement pipe during rigid concrete pouring is high, while the air humidity in the air is low, so the surface will volatilize and dry, but the interior is still plastic, This causes cracks. The other is caused by the temperature difference between the inside and outside of the concrete caused by the water cement ratio when the cement pipe is hardened. For deeper cement pipes, the foundation will continue to settle due to its own weight during the whole process of concrete pouring of the top cement pipe. Then, when the cement pipe is exposed to building reinforcement or the connecting anchor bolt of the template and other items just before the final setting but not before the final setting, this kind of foundation settlement will be blocked and will immediately cause cracks.

1. The principle of overflow well discharge method: the sewage is mainly discharged into the municipal sewage pipe through the overflow well, and the pump is used as a supplement to remove the accumulated water in the overflow well and the upstream sewage pipe. The flow should be confirmed by discharging all accumulated water within 30min. In order to reduce the operation cost, the sewage pump can be started before the peak water consumption every day to drain the accumulated water in the overflow well and the upstream pipeline. This can not only prevent sewage from staying in the pipeline for a long time and forming siltation, but also make the ponding pipe section often washed, which is conducive to pipeline ventilation and the removal of harmful gases in the pipeline.

The general defect is corrosion, which mainly includes pitting and erosion. These two corrosion modes are chronic and not easy to be found by testers. The other is stress corrosion cracking, which is caused by corrosion, tension and stress at the same time. Mechanical damage is also a defect of cement pipes, mainly including gouges and dents with gouges, which are usually caused by mechanical loss. External crack defects are plane defects of cement pipes, which are easy to be found. Peeling is a serious wear condition, and perforation will cause fracture or leakage. Therefore, cement pipes should be tested in time. Once defects are found, corresponding repair measures should be taken immediately to eliminate potential safety hazards and ensure safety.
