Aluminum Duct is a more popular on the market of a pipe, the market is more famous on the abundance and Jinde, because of its light, durable and easy construction, its flexibility is more suitable for use in home improvement. The main drawback is that when used as a hot water pipe, due to long-term thermal expansion and contraction will cause the wall dislocation caused by leakage. Aluminum Duct inside and outside are special polyethylene material, clean non-toxic, smooth. Can be used for more than 50 years. The middle aluminum layer can be 100% isolated gas infiltration, and the tube at the same time with the advantages of metal and plastic tube, and remove their own shortcomings.
Aluminum Duct is a new type of pipe made of middle longitudinal aluminum pipe, inner and outer polyethylene plastic and hot melt adhesive coats between layers and layers. Polyethylene is a non-toxic, odor-free plastic, with good impact resistance, corrosion resistance, weather resistance. The middle layer of vertical welding aluminum alloy pipe with a metal pressure strength, impact resistance to make the pipe easy to bend does not rebound, aluminum-plastic composite pipe has a strong metal pipe and plastic pipe anti-acid corrosion resistance of the two major characteristics, is the new A generation of pipe model. Aluminum-plastic pipe (aluminum-plastic composite pipe) is a more popular on the market of a pipe, the current market is more famous on the abundance and Jinde, because of its light, durable and easy construction, and aluminum pipe (aluminum composite pipe ) Flexibility is more suitable for use in home improvement. Aluminum plastic pipe (aluminum-plastic composite pipe) The main drawback is used in the use of hot water pipes, due to long-term thermal expansion and contraction will cause the wall dislocation caused by leakage. Beijing is a lot of residential use of aluminum-plastic pipe (aluminum-plastic composite pipe), in the decoration of the relatively new concept of Guangdong and Shanghai, Aluminum Duct aluminum-plastic pipe (aluminum-plastic composite pipe) has gradually no market, the current aluminum-plastic Tube) in the Beijing market is still relatively active, I believe that in the near future, the Beijing market aluminum-plastic pipe (aluminum-plastic composite pipe) will also be eliminated.
According to the use of classification of ordinary drinking water pipes, high temperature tubes, gas pipes, various types of pipe features and uses are as follows:
① ordinary drinking water with aluminum composite pipe: white L logo, the scope of application: domestic water, condensate, oxygen, compressed air, other chemical liquid pipeline.
② high temperature with aluminum composite pipe: red R logo, mainly for long-term working temperature of 95 ℃ hot water and heating pipe system.
③ aluminum-plastic composite pipe for gas: Aluminum Duct yellow Q logo, mainly used for conveying natural gas, liquefied petroleum gas, gas pipeline system.
④ pipe construction, must comply with the corresponding technical regulations.
Use of the following three important:
1 hot and cold water piping system
All-round aluminum-plastic composite pipe inside smooth, non-corrosive, not knot scale, 30% greater than the metal pipe flow. Easy to bend, can be directly over the beam and column installation, can be buried in the walls and concrete, with a simple metal detector, will be able to detect the installation where, so the tube is very suitable for industrial and civil construction of hot and cold water pipes System used.
2 indoor gas pipeline system
Longitudinal welded Aluminum Ducts are sandwiched between plastics, allowing the omnipotent tube to withstand higher working pressures, allowing the gas (oxygen) permeability to zero, and the length of the pipe can be reduced to avoid leakage, so the tube is used to compress air, , Oxygen and other gas transmission lines are safe and reliable.
3 solar air conditioning piping system
All-round aluminum-plastic composite pipe is not easy to frost, Aluminum Duct good insulation, improve the efficiency of solar energy and air conditioning systems.
