Corrosion resistance and leakage resistance, PE water supply pipe to ensure the safety of Xiaogan water supply

The PE water supply pipe is a special water supply pipe produced by extrusion molding process using high-density polyethylene as the core raw material. It has been widely used in the water supply system at all levels in Xiaogan area. It mainly undertakes the long-distance transportation and end point distribution functions of drinking water and municipal public water. The performance of the pipe material conforms to the relevant production standards of the national water supply pipeline. It can be adapted to various installation needs such as ground laying and buried laying in different geological conditions and climatic environments in Xiaogan. It is the mainstream water supply product that replaces traditional galvanized steel pipes and cement pipes.

The core practical selling points mainly include four items: First, the corrosion resistance is suitable for local geology, the soil acid and alkali value in some areas of Xiaogan is high, and some pipe networks need to pass through high humidity and high humus areas around rivers and lakes. The PE water supply pipe itself has stable acid and alkali resistance and chemical corrosion resistance, and will not be eroded by corrosive components in the soil and groundwater impurities. Long-term buried use will not cause pipe wall corrosion or perforation problems, and there is no need to apply additional anti-corrosion coatings, which can effectively reduce the maintenance cost of the later pipe network. Second, anti-leakage structure to reduce water loss, PE water supply pipe using hot-melt socket, hot-melt butt connection process, the interface material and the pipe body is completely melted into one, the overall sealing is far better than the traditional bite type, bonding connection of the pipeline, conventional models can withstand 1.0-1 MPa of water pressure, will not disconnect the interface, pipe wall leakage problem, adapt to Xiaogan high-rise residential water supply, long-distance pipe network transportation pressure demand, can effectively reduce the leakage rate of water supply pipe network. Third, the hygiene performance standards to ensure the safety of drinking water, PE water supply pipe production of raw materials are in line with food contact material safety standards, pipe wall smooth and not easy to scale, the use of the process will not breed bacteria, precipitation of harmful components, long-term transport of drinking water will not cause secondary pollution of water quality, in line with Xiaogan residents drinking water hygiene management requirements. Fourth, the construction is convenient to adapt to multiple scenarios. The weight of PE water supply pipes is only one-eighth of that of steel pipes of the same specification, and the difficulty of transportation and hoisting is low. At the same time, it is suitable for construction techniques such as trenchless pipe jacking and directional drilling, which can meet the needs of the pipeline network transformation in Xiaogan's old city and the laying of pipelines under the core section that are not suitable for large-scale excavation. This can greatly shorten the construction period and reduce the impact of construction on the normal travel and life of residents.

At present, the applicable scenarios of this type of PE water supply pipe cover the construction and renovation projects of municipal public water supply pipe network in Xiaogan area, the laying of water supply risers and front branches in urban residential areas, the construction of pipeline network of township centralized drinking water safety projects, and the transportation of harmless production water in industrial plants. Suitable groups include Xiaogan local municipal water supply engineering construction units, real estate development enterprises, township water supply operation entities, and industrial plant infrastructure construction responsible parties and other pipeline selection purchasers. Pipe products with corresponding pressure levels and specifications can be selected according to the actual transmission medium and pressure requirements.

At present, the production, construction and acceptance of PE water supply pipes strictly follow the relevant standards of the national "Polyethylene (PE) Pipeline System for Water Supply". Before entering the market, pipes need to pass the pressure-bearing performance, hygiene performance, corrosion resistance and other indicators of a third-party authoritative organization. All parameters can be installed and used after meeting the standards, which can effectively provide reliable hardware support for the long-term stable and safe operation of the water supply system in Xiaogan.
