※ Product Introduction
Using high-strength steel wire (or steel wire mesh) as the skeleton reinforcement layer, the inner and outer layers are wrapped in high-density polyethylene (HDPE), and bonded by hot melt adhesive to form a "steel wire skeleton PE" composite structure. The steel wire skeleton provides rigid support and tensile strength, while the PE layer ensures corrosion resistance and flexibility, achieving a performance balance of "rigid flexible combination". The steel wire skeleton polyethylene composite pipe combines the strength of metal and the corrosion resistance of plastic through a "steel plastic composite" structure, and has both performance advantages and economy in pressure transportation scenarios. It is one of the ideal pipes for municipal, gas, and industrial fields.
※ Product Features
1. High strength, high pressure resistanceThe compressive strength of the pipe material is much higher than that of pure PE pipe. Under the same pressure requirements, the wall thickness can be thinner, which saves more materials;
2. Excellent corrosion resistanceBoth the inner and outer layers are made of polyethylene, which has excellent chemical stability and good corrosion resistance to chemicals, acids, alkalis, and salts in the soil
3. Good creep resistancePolyethylene undergoes creep under continuous pressure, and the reinforcing effect of steel wire mesh greatly suppresses this deformation, ensuring the long-term dimensional stability and pressure bearing capacity of the pipeline system;
4Lightweight, easy to transport and installCompared to traditional metal pipes such as ductile iron pipes and steel pipes, it is much lighter in weight and greatly reduces the strength of handling and construction; Good hydraulic performance: smooth inner wall, low friction coefficient, low water transmission energy consumption, not easy to scale, and long-term stable water flow capacity;
5. Low coefficient of thermal expansionSteel wire mesh limits the thermal expansion of polyethylene, and its coefficient of linear expansion is much lower than that of pure plastic pipes.
※ Implementation standards
GB/T 32439-2015 "Steel Wire Mesh Reinforced Polyethylene Composite Pipes for Water Supply"
※ Pipe connection method
1、 Electric fusion connection:
Heat and melt the PE layer with specialized electric melting fittings (electric resistance wires), and after cooling, form an integrated joint with strong sealing performance.
2、 Flange connection:
Used for large diameters (DN 200 and above) or docking with metal equipment, it needs to be equipped with rubber sealing rings, which have strong pressure resistance but high installation costs.
※ Application Fields
Municipal water supply network, industrial drainage, water conservancy construction, urban pipeline network renovation, agricultural irrigation and water conservancy, and other fields.
