HDPE steel mesh skeleton pipe, material for urban pipe network construction

Core Performance Advantages of HDPE Steel Mesh Skeleton Pipe for Urban Pipe Network

As a new type of plastic pipe with steel-plastic composite structure, HDPE steel wire mesh skeleton pipe not only retains the characteristics of HDPE material corrosion resistance, smooth inner wall, low transmission resistance, hygiene and non-toxicity, but also overcomes the defects of pure plastic pipe creep and insufficient pressure bearing capacity through the intermediate steel wire reinforcement layer. The pressure bearing grade of conventional products can cover the range of 0.8MPa to 3.5MPa, and the service life can reach more than 50 years. It is suitable for urban water supply, recycled water transportation, weak electric wiring, low pressure gas transportation and other types of pipe network construction scenarios. Compared with traditional steel pipes and cement pipes, it is lighter in weight and has lower transportation and installation costs.

Key Points for Pipeline Selection in Urban Pipeline Network Projects

According to the use needs of different urban pipe networks, the selection should first match the pressure requirements of the project. Products with higher pressure levels should be selected for sections with larger buried depths. Pipe networks for transporting drinking water should be selected to meet food contact grade standards. Pipe networks for transporting corrosive media need to additionally confirm the chemical corrosion resistance parameters of the pipes. At the same time, it is necessary to check whether the appearance of the pipes is flat, whether the steel mesh layer and the inner and outer HDPE layers are closely bonded, and the matching hot melt pipe fittings need to be fully matched with the pipe specifications and pressure levels to avoid later interface leakage.

Key points of construction specification for HDPE steel mesh skeleton pipe

Before construction, it is necessary to clean up the sharp stones and construction waste in the trench to avoid scratching the outer wall of the pipe; during hot melt docking, the heating temperature and docking pressure should be strictly controlled, and the heating and cooling time should be adjusted according to the ambient temperature. In low temperature environment, the construction needs to do a good job of pipe insulation protection to avoid material embrittlement affecting the strength of the interface. When backfilling, it is necessary to fill it with fine sand or fine soil to 30 cm above the top of the pipe, and then backfill it layer by layer. Heavy machinery is strictly prohibited from directly rolling uncovered pipes. After the construction is completed, it is necessary to conduct closed water and pressure tests according to the specifications to confirm that there is no leakage before putting it into use.

With the continuous release of demand for urban pipe network renewal and transformation, HDPE steel wire mesh skeleton pipes have become one of the mainstream materials for domestic urban pipe network construction due to their comprehensive performance advantages.
