Steel mesh skeleton pipe, the first choice for large-scale water supply projects in Hubei

The steel wire mesh skeleton pipe is a new type of composite pipe made of high-strength steel wire spiral wound left and right mesh skeleton as the reinforcement body, high-density polyethylene as the matrix, and the steel wire skeleton is closely connected with the inner and outer layers of polyethylene through a high-performance adhesive resin layer. The conventional nominal pressure range is 0.8MPa-3.5MPa, and the nominal diameter range is 50mm-800mm. It can be flexibly selected according to the transportation pressure and flow requirements of different projects, and is suitable for different scales of water supply and transportation needs.

The core advantages of this type of pipe mainly include four points: First, the structural stability is strong, and the steel wire reinforcement layer greatly improves the axial and circumferential tensile strength of the pipe. Under the same pressure level, the wall thickness of the pipe can be reduced by about 30% compared with pure polyethylene pipe. The anti-settlement performance is suitable for the geological conditions of Hubei hills and plains, and it is not easy to deform and crack after long-term use. Second, the fluid transportation efficiency is high, the inner wall smoothness of the pipe is higher than that of traditional metal pipes, and it is not easy to scale. The resistance loss along the way is 15% -20% lower than that of the same diameter cast iron pipe, which can reduce the long-term operation and maintenance energy consumption of the water supply system. The third is that the hygienic performance is up to standard. The inner and outer polyethylene materials meet the safety evaluation standards of drinking water transmission and distribution equipment and protective materials. There is no harmful component precipitation, and it can be directly used in drinking water transportation scenarios. Fourth, it is easy to install and maintain. The weight of the pipe is about 1/7 of the same specification steel pipe, which is convenient for construction site transportation. It can be connected by electric hot melt. The interface has good sealing performance. The construction period is shortened by about 40% compared with traditional metal pipes, reducing the comprehensive construction cost of the project.

In addition to being suitable for the construction of large-scale water supply main pipe networks in Hubei and the upgrading of old urban and rural water supply systems, the pipe can also be used in scenarios such as industrial room temperature fluid transportation, municipal low pressure sewage discharge, and fire protection pipe network construction. It is suitable for the pipe procurement needs of various entities such as municipal engineering construction units, water supply operation service enterprises, industrial project investors, and civil infrastructure project contractors.

The performance of this type of pipe meets the current national standards for steel mesh skeleton plastic composite pipes and relevant specifications for urban water supply engineering construction. The purchaser can select the type according to the actual pressure, caliber and laying environment requirements of the project, and the qualified products purchased through regular channels can provide the authoritative test report of the corresponding batch to fully ensure the compliance and stability of the project application.
