It is better to use aluminum-plastic pipes
An anti-aging agent is added to aluminum-plastic pipes, which has good temperature resistance and pressure resistance, wide operating temperature range and 100% gas penetration insulation, oxygen and light impermeability, and inhibits. It has the same strength as metal pipes and is easy to bend. It does not bounce back after folding. It is easy to install and maintain.
Because aluminum-plastic pipes are easy to leak or crack.
It can be said that aluminum-plastic pipes are widely used and of good quality, but at present, aluminum-plastic pipes have been eliminated. Because when the metal joints are connected to the aluminum-plastic pipes, they are pressed together. Although the operation is simple, the reliability is not good and it is easy to leak.
But this does not mean that aluminum-plastic pipes are necessarily bad, it only means that the entire pipeline system is not very reliable.
If the aluminum-plastic pipe is really qualified, the quality should be acceptable, but regarding material problems, domestic materials and corresponding joints, there may be problems. For example, cracks during bending or water leaks at joints are some of the reasons why aluminum and plastic pipes have been eliminated.
There is also a problem with the material, as aluminum is not good and can easily crack when bent.
Uses of aluminum-plastic pipes:
1. Hot and cold water pipe systems.
The interior of the aluminum-plastic composite pipe is smooth, non-corrosive and does not form scale. It has a 30% higher flow ratehigher than that of metal pipes. Aluminum-plastic pipes are easy to bend and can be installed directly around beams and columns. They can be buried in walls and concrete. A simple metal detector can detect the location of the installation.
2. Domestic gas pipeline system.
The longitudinally welded aluminum pipe is sandwiched between plastics, allowing the versatile pipe to withstand higher working pressures, so that gas (oxygen) permeability is zero and the Long hose can reduce joints and prevent leaks. so this priming hose is safe and reliable when used in compressed air, gas, oxygen and other gas transmission lines.
3. Solar air conditioning piping system.
Aluminum-plastic composite pipes are not easy to frost, have good thermal insulation properties, and improve efficiencyity of solar energy and air conditioning systems.
