Xiangyang Yichang steel mesh skeleton water supply pipe, the first choice for engineering procurement

The steel mesh skeleton water supply pipe adapts to the advantages of Xiangyang Yichang project scene

In the hilly and mountainous areas of Xiangyang and Yichang, municipal water supply, pipe network renovation of old residential areas, and water supply matching in industrial parks have high requirements on the pressure-bearing capacity, settlement resistance, and corrosion resistance of pipelines. The steel mesh skeleton water supply pipe is reinforced by a high-strength steel wire wound skeleton, and the internal and external composite high-density polyethylene materials. The pressure-bearing capacity is more than 30% higher than that of ordinary PE water supply pipes. It can adapt to the pressure difference of the pipe network in mountainous terrain. At the same time, it is resistant to soil acid and alkali, anti-aging, and the buried service life can reach 50 years. It is suitable for the humid, rainy, and highly corrosive soil in the south, which greatly reduces the maintenance cost of the later pipe network.

Core reference standard for engineering procurement selection

When purchasing, we must first match the pressure level requirements of the project. It is recommended to choose 1.6MPa and above specifications for the municipal trunk water supply pipe. The secondary water supply of the branch network and the community can choose 1.0-1 25MPa specifications according to the actual needs. Secondly, we must check the appearance of the pipe. It is required that the pipe wall is flat without bubbles and cracks, the port steel wire is not exposed, and the sealing is uniform. The diameter and wall thickness of the pipe meet the requirements of the national standard, and it can be adapted to the project flow design standard. According to the characteristics of Xiangyang Yichang mountainous area, the conventional specifications with verified anti-settlement performance can be preferred to reduce the risk of leakage of the later pipe network.

Construction and operation and maintenance precautions

The steel mesh skeleton water supply pipe adopts the electric hot melt connection method. Before construction, the stains and water stains on the pipe port need to be cleaned up. The hot melt temperature is controlled in the range of 210-230 ° C. During high temperature construction in Xiangyang and Yichang in summer, it is recommended to avoid the noon period to prevent the thermal expansion and contraction of the pipe from affecting the connection sealing. During winter construction, the port needs to be pre-warmed to avoid brittle cracking. When laying the pipeline, the bottom needs to be laid with a fine sand layer of more than 10cm to avoid sharp stones and construction waste scratching the pipe wall. After completion, a closed water test of 1.5 times the working pressure needs to be done according to the specification. After confirming that there is no leakage, it can be backfilled.

At present, among various water supply projects in Xiangyang and Yichang, the proportion of steel mesh skeleton water supply pipes is increasing year by year. Compared with traditional ductile iron pipes, the weight is lighter, the transportation and construction costs are lower, and the comprehensive adaptability is stronger. It is a cost-effective choice for water supply engineering procurement.
