What is aluminum-plastic composite pipe?
As a new type of pipe, the aluminum-plastic composite pipe adopts the method of physical compounding and chemical compounding in the butt welding process. The polyethylene is in a high-temperature molten state, the aluminum pipe is in a heated state, and a layer of glue is added between the aluminum and the polyethylene. The bonding agent forms a five-layer structure of polyethylene, adhesive, aluminum tube, adhesive, and polyethylene.
The five-layer material is integrated into a whole by high temperature and high pressure, which forms the new composite pipe, which fully embodies the respective advantages of metal materials and plastics and makes up for their shortcomings. The aluminum-plastic composite pipe has good anti-aging performance, cold and brittle temperature bottom, anti-ultraviolet radiation, and has a service life of more than 50 years without high heat and strong ultraviolet radiation.
The aluminum-plastic composite pipe is made of high-strength welded aluminum pipe, which strengthens the polyethylene, has small expansion coefficient, stable size, clean, non-toxic, smooth, large flow, and has certain elasticity, which can effectively reduce the water hammer phenomenon in the water supply. And fluid pressure shock and noise. It has a wide range of applications, and can be applied to water supply and hot water pipe agricultural and horticultural pipes, heating pipes, industrial pipes, hot spring pipes, solar energy pipes, public utilities pipes, etc., which are convenient and quick in engineering construction. The construction period, colorful and beautiful, is an ideal replacement for galvanized pipes.
Classification of composite pipes
1 aluminum-plastic composite pipe. The aluminum-plastic composite pipe is a five-layer pipe with a layer of welded aluminum alloy in the middle and a layer of polyethylene inside and outside, which is bonded by glue layer. It has the advantages of good corrosion resistance of polyethylene plastic pipe and high pressure resistance of metal pipe. Aluminum-plastic composite pipes are divided into two types according to different polyethylene materials: cross-linked polyethylene-aluminum-plastic composite pipe suitable for hot water and high-density polyethylene-aluminum-plastic composite pipe suitable for cold water. The specifications of aluminum-plastic composite pipe are Φ14～Φ32, which are connected by clamped copper fittings. They are mainly used for water distribution pipes and water heater pipes in buildings, and the price is relatively expensive.
2 steel-plastic composite pipe. The steel-plastic composite pipe is made of UPVC plastic with a certain thickness on the inner wall of the galvanized pipe, so it has the superiority of steel pipe and plastic pipe at the same time. The pipe specifications are Φ15-Φ150. It is connected by copper fittings and threaded, and the water temperature is below 50 °C. It is used as a building water supply cold water pipe, which is more expensive.
3 steel skeleton PE pipe. The steel skeleton PE pipe is made of high-quality low-carbon steel wire as the reinforcing phase and high-density polyethylene as the base. The new double-sided anti-corrosion pressure is continuously formed on the production line by synchronously filling and injecting the steel wire into the net and plastic. pipeline. The pipe diameter is Φ50～Φ500, and the flange is connected. It is mainly used in municipal, chemical and oilfield pipe networks, and the price is relatively expensive.
4 plastic coated steel pipe. The plastic coated steel pipe is melted on the inner wall of the steel pipe with a thickness of 0.5 to 1.0 mm of polyethylene (PE) resin, ethylene-acrylic acid copolymer (EAA), epoxy (EP) powder, non-toxic polypropylene (PP) or none. Steel-plastic composite pipe made of organic materials such as polyvinyl chloride (PVC), which not only has the advantages of high strength, easy connection and water flow impact of steel pipes, but also overcomes the corrosion, pollution, scaling and plastics of steel pipes. The pipe has low strength and poor fire performance, and the design life can reach 50 years. The main disadvantage is that when the installation is not carried out, the cutting surface should be applied with the non-toxic room temperature curing glue provided by the manufacturer when bending, hot working and electric welding cutting. The main specifications are Φ15-Φ100.
