Price of Zhangjiakou cement pipe

1、 Factors affecting the price fluctuation of reinforced concrete cement pipes. 1. The quality of materials used for cement pipes will affect the price of cement pipes: generally speaking, the price of cement pipes will be slightly higher than the market average price if the quality of raw materials used for cement pipes is high, while the price of cement pipes with ordinary quality will be slightly lower. 2. The manufacturing process of cement pipes will also affect the price of cement pipes: generally, different types of cement pipes adopt different manufacturing processes, some are complex and tedious, some are simple and take less time, so the prices of different cement pipes will be different.

Principle of pipeline well crossing method: when the cement pipeline meets the crossing of existing pipelines or rainwater and sewage pipes during burial, the pipeline well crossing method is adopted, which can reduce the buried depth of the pipeline and is not easy to block. An inspection well shall be set at the intersection of pipelines to let another pipeline pass through the well. The key is to ensure that the water flowing area in the well (the area of the shadowed part in the figure) is greater than or equal to the sectional area of the pipeline to be passed through. The size of the water flowing area in the well can be controlled by the size of the pipe passing inspection well. The principle of pipe passing is small pipe passing through large pipe, and the current pipeline passing through the planned 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.

Temperature: for the solidified mortar layer or concrete component, if the cement pipe factory is often in high temperature and extreme heat conditions, there will be strength loss. This is because the calcium hydroxide in the cement stone will be separated under high temperature conditions. In addition, some aggregates will separate or expand in volume under high temperature conditions. Cement raw materials: when selecting cement, cement varieties with high strength, good durability, appropriate price and reliable quality should be selected. The cement varieties with special properties shall be selected according to the service conditions of cement pipes; It is an important condition to ensure the durability of cement pipes to select better sand and stone aggregates, and sand and stone aggregates with good quality and qualified technical conditions.
