Steel wire mesh reinforced plastic composite pipe, also known as steel wire mesh reinforced polyethylene composite pipe for water supply, is a new type of low, medium, and high-pressure composite pipe. It uses high-strength, plastic-coated steel wire wound into a mesh as reinforcement, bonded with hot melt adhesive, and has inner and outer layers of double-sided PE plastic. Because the reinforcement is encased in continuous thermoplastic plastic, this type of composite pipe overcomes the disadvantages of both steel and plastic pipes, possessing their combined advantages. It represents a breakthrough technological achievement in solving the problems of building and municipal water supply pipelines, and also addresses the urgent need for large-diameter rigid pipes in the petroleum, chemical, pharmaceutical, food, mining, and gas industries. The pipeline system uses electrofusion fittings for connection, utilizing an internal heating element in the fitting to melt the outer plastic layer of the pipe and the inner plastic layer of the fitting, reliably connecting them together.
Pipe Structure:
The structural feature of steel wire mesh reinforced polyethylene (PE) composite pipes is the presence of two or more layers of wound steel wire mesh reinforcement between the inner and outer pipe walls.
The reinforcing steel wire is high-strength coated steel wire, and before winding, it is coated with a layer that provides hot-melt bonding and water resistance. After winding onto the core pipe, the pipe undergoes heating, extrusion coating of the intermediate bonding layer, and extrusion coating of the outer PE layer, ensuring a hot-melt bond between the high-strength steel wire and the inner and outer PE layers. This results in a composite pipe with excellent performance.
Product Introduction:
Implementation Standards: Hygiene indicators comply with the provisions of GB/T17219-1998 “Safety Evaluation Indicators for Drinking Water Transmission and Distribution Equipment and Protective Materials”. Product standards comply with CJ/T189-2007.
1. The product implementation standard is: CJ/T189-2007 “Steel Wire Mesh Reinforced Plastic (Polyethylene) Composite Pipes and Fittings”.
2. Composite pipes of the same specification but different pressure ratings have different steel wire diameters and mesh parameters; special operating conditions require separate negotiation between the supplier and the buyer.
3. The nominal pressure is the maximum operating pressure of the pipe material for conveying water at 20°C. Correction should be made if the medium temperature changes.
Product Advantages:
◆ Hygienic and Environmentally Friendly with Low Expansion Coefficient: Made from high-density polyethylene raw materials, it is hygienic, non-toxic, weather-resistant, long-lasting, and produces no secondary pollution. Under the constraint of the mesh steel skeleton, the thermal expansion of the composite pipe is greatly improved, resulting in high stability.
◆ Excellent Weldability and Pressure/Impact Resistance: Utilizing electrofusion connection, it is leak-proof and has excellent sealing performance. The electrofusion joint has strong axial tensile strength, higher pressure resistance, and creep resistance, making it less susceptible to damage from external forces.
◆ Smooth Inner Wall, Corrosion and Scale Prevention: Employing an internally shaped composite process, its inner surface is smoother than that of plastic pipes, preventing scale buildup and ensuring strong flow capacity. Double-sided corrosion protection provides excellent resistance to acids, alkalis, and chemical corrosion.
◆ Reliable Connection and Convenient Construction: Lightweight for easy transportation and construction; buried steel wire mesh reinforced plastic (polyethylene) composite pipes can be located using magnetic detection, avoiding damage caused by other excavation operations.
◆ Lightweight and easy to install: Lightweight for easy transportation and construction; the steel wire mesh reinforced plastic (polyethylene) composite pipe buried underground can be located by magnetic detection, avoiding damage caused by other excavation operations.
