Hole-web steel belt plastic composite pipe product structure:
This product is a new type of composite pressure pipe material made of cold-rolled steel strips and thermoplastic plastics. It features a reinforced structure with porous thin-walled steel tubes焊接 using argon arc welding, and both the outer and inner layers are made of double-sided composite thermoplastic plastics. As the porous thin-walled steel tube reinforcement is encapsulated within continuous thermoplastic plastic, this composite pipe overcomes the individual drawbacks of steel and plastic pipes while retaining their combined advantages. It represents a revolutionary technological achievement for addressing the needs of building and municipal water supply main pipelines following the ban on galvanized pipes. It is also an essential pipeline for the urgent requirements of large and medium-sized diameter rigid pipes in the oil, chemical, food, mining, and gas industries, and is a new composite pipeline for the 21st century.
The pipe system for steel plate hole plastic composite pipes uses electro-heat fusion fittings. During connection, the internal heating element of the fitting melts the outer plastic layer of the pipe material with the inner plastic layer of the fitting, securely bonding the pipe material to the fitting.
　　Hole Mesh Steel Strip Plastic Composite Pipe Product Features:
1. Offers higher strength, rigidity, impact resistance, with a low expansion coefficient and蠕变resistance similar to steel pipes.
2. Double-sided corrosion protection, with the same corrosion resistance as plastic pipes, and also corrosion-resistant. Increased operating temperature.
3. Low thermal conductivity; no need for insulation on the exterior wall in winter, and no condensation in summer.
4. The inner wall is smooth and non-scaling, with a 30% lower head loss compared to steel pipes.
5. Pipeline connections utilize electric heat fusion, a mature technology with a wide variety of pipe fitting specifications and types.
6. Lightweight, easy transportation and construction.
7. Adjust the steel plate and plastic thickness to manufacture pipes of various pressure ratings. It allows for easy modification of reinforcement parameters, enabling the production of pipes with different pressure resistance levels.
8. High-temperature-resistant plastics such as medium-density polyethylene and atactic polypropylene (PP-R) can be used to produce temperature and pressure-resistant piping materials.
9. The overall reliability of the pipe material is high, with a service life of up to 50 years under normal conditions.
10. Low cost, hygienic, and non-toxic, it is a preferred substitute for galvanized pipes.
11. The reinforcement and plastic are integrated into a single structure, with the plastic layers on both inner and outer walls nearly impossible to peel off. The composite layer contains no adhesive, and is sealed using thermal welding rings and electric thermal fusion pipe fittings. As a pipeline connection, it is similar to the hot melt or electric thermal fusion processes for general plastic pipes, without concerns of plastic layers peeling off from the inner and outer walls or the reinforcement.
12. The electrical heat melting接头 exhibits strong resistance to axial tension. Through the pores, the electrical heat melting pipe fittings are actually integrated with both the inner and outer walls of the pipe, as well as with the reinforced frame.
　　Hole Mesh Steel Strip Plastic Composite Pipe Technical Requirements：
1. Colors are typically black, blue, or white; high-temperature-resistant pipes are usually orange, or can be agreed upon by both parties based on supply and demand.
2. The inner and outer surfaces of the pipe should be smooth and even, allowing for minor indentation and protrusions due to natural shrinkage, but no bubbles, cracks, decomposition变色 lines, or visible scratches are permitted. The ends of the pipe should be cut cleanly.
3. The pipe end caps seal the pipes effectively, with no cracks, smooth joints, and no scratches or burrs.
