Composite Pipe
Aluminum plastic composite pipe is a new type of pipeline material that combines the advantages of metal aluminum and plastic. Aluminum plastic composite pipes consist of inner and outer layers of plastic and an intermediate layer of aluminum foil. This three-layer structure not only endows the pipeline with good corrosion resistance and sealing, but also greatly enhances its compressive strength and service life. The internal plastic layer is usually made of polyethylene (PE) or polypropylene (PP), while the external plastic layer may use polyvinyl chloride (PVC) or other materials to adapt to different working environments and media.

Materials of Construction
Aluminum materials have low density, high strength, good electrical and thermal conductivity, good corrosion resistance, easy to process
Aluminum has a low density, about one-third that of iron or copper; Aluminum has high strength, with a tensile strength of about 80MN/㎡ for pure aluminum, which is one-fifth that of low-carbon steel; The electrical and thermal conductivity of aluminum is second only to silver, copper, and gold; The surface of aluminum is prone to naturally produce a dense and firm AL2O3 protective film, which can effectively protect the substrate from corrosion; After adding certain alloying elements, cast aluminum alloys with good casting performance or deformed aluminum alloys with good processing plasticity can be obtained.
Structural characteristics: The basic composition of aluminum-plastic composite pipes should be five layers, namely plastic, hot melt adhesive, aluminum alloy, hot melt adhesive, plastic, etc., from the inside out. This five layer structure allows aluminum-plastic composite pipes to have the characteristics of both plastic and metal pipes. Aluminum plastic composite pipe (PAP) is a new type of pipe that combines the advantages of metal and plastic. Its structure consists of an outer wall and an inner wall made of chemically cross-linked polyethylene, with a layer of approximately 0.3mm thin aluminum plate welded in the middle; There is a layer of adhesive firmly bonded between the aluminum tube and the inner and outer layers of polyethylene.
Physical and chemical performance characteristics
Corrosion resistance: The inner and outer walls are made of highly chemically stable cross-linked polyethylene, which not only does not corrode in water, but can also resist most corrosive chemical liquids such as strong acids and alkalis.
Non rebound: Due to the presence of a highly plastic aluminum tube layer, aluminum-plastic composite pipes can be bent to become straight or straight to bend and maintain their changed shape.
Good barrier performance: Welding dense aluminum tubes can completely prevent penetration inside and outside the tube wall.
High density: For pipes of the same diameter and length, aluminum-plastic composite pipes are about 1/7 the mass of steel pipes.
Easy to install: No need for threading or cutting, easy to connect. The pipe has a long length and high economy.
High temperature resistance: Aluminum plastic composite pipes made of cross-linked polyethylene can work continuously in media above 95 ℃.
Good reliability: The service life can reach 50 years.
Low flow resistance: The inner wall is smooth without scaling, and the flow rate is higher than that of a metal tube with the same inner diameter.
Aesthetics: The outer wall of aluminum-plastic composite pipes can have different colors, and visible pipe construction does not require painting.
Easy to detect: with metallic aluminum, the location can be easily identified after concealed construction.
Anti static: can be used to transport various flammable fluids
The use of aluminum-plastic composite pipes
Aluminum plastic composite pipe is a widely used pipe material, and its main uses are as follows
Aluminum plastic composite pipes for ordinary drinking water：
Aluminum plastic composite pipes for ordinary drinking water use the white L mark, which is applicable to pipelines for domestic water, condensate water, oxygen, compressed air, and other chemical liquids.
Aluminum plastic composite pipes for high temperature resistance
Aluminum plastic composite pipes with high temperature resistance use the red R mark, mainly used for hot water and heating pipeline systems with a long-term working water temperature of 95 ℃.
Aluminum plastic composite pipe for gas use
The aluminum-plastic composite pipe used for gas is marked with a yellow Q symbol, mainly used for transporting natural gas, liquefied gas, and coal gas pipeline systems.
Aluminum plastic composite pipes have a wide range of applications. In addition to the three main uses mentioned above, they can also be used as pipes for cold and hot water pipeline systems, indoor gas pipeline systems, solar energy and air conditioning systems in industrial and civil buildings
