Stable supply of steel mesh skeleton pipes for urban and rural water supply reconstruction

Core requirements for pipeline materials in urban and rural water supply transformation

The current urban and rural water supply renovation projects cover a wide area, involving plains, mountains, saline-alkali land and other complex geology, and have high requirements for the compression resistance, corrosion resistance and service life of pipelines. The steel mesh skeleton pipe is based on a steel wire reinforced structure, which has both the corrosion resistance of plastic pipes and the tensile resistance of metal pipes. The pressure bearing capacity is suitable for most municipal water supply pressure standards. There is no leakage and deformation of the pipe wall in long-term use. The acid and alkali corrosion resistance is suitable for most urban and rural soil environments. The service life can reach more than 50 years, which is much higher than that of traditional cement pipes and ordinary PE pipes. It can effectively reduce the later operation and maintenance costs of the water supply pipe network. It is the mainstream selection of current water supply renovation projects.

Key Points for Selection and Construction of Steel Mesh Skeleton Pipe

In the selection stage, the corresponding parameters need to be matched according to the project water supply pressure and laying scene. The supervisor network recommends choosing large-diameter pipes with higher pressure bearing grade, and small-diameter pipes with suitable flow rate can be selected for home branches to avoid pipe explosion and insufficient water supply caused by parameter discrepancies. During the construction stage, the hot-melt connection temperature should be strictly controlled, and the dust and impurities at the pipe interface should be cleaned before connection. The hot-melt time should be adjusted according to the pipe diameter to avoid interface leakage caused by virtual welding. When laying in the ground, the burial depth should be set according to the thickness of the local frozen soil layer, and the sharp stones should be cleaned at the bottom of the pipe groove to avoid external extrusion damage to the pipe structure. After the construction is completed, the pressure test should be done according to the specifications, and the backfill operation should be carried out after confirming that

Core Guarantee of Stable Supply of Steel Mesh Skeleton Pipe

Urban and rural water supply renovation projects generally have a tight construction period and large quantities of materials. Stable supply is the core premise to ensure the delivery of the project on schedule. The supplier needs to have sufficient production capacity reserves, and the amount of pipes of different diameters and parameters is sufficient. The production rhythm can be flexibly adjusted according to the project progress, and large quantities of orders can be delivered in a short time. The logistics distribution system needs to cover remote areas in urban and rural areas, which can realize point-to-point delivery to the construction site to avoid pipe loss caused by halfway transshipment. At the same time, the supporting basic on-site technical guidance services assist the construction party to complete key links such as interface processing and stress testing, and reduce the delay in the construction period caused by improper operation.

With the acceleration of the integration of urban and rural water supply, the application scale of steel mesh skeleton pipes will continue to expand. A stable supply system and standardized selection construction can effectively ensure the stability of the water supply network and improve the water quality and water experience of urban and rural residents.
