Aluminum-plastic composite pipe is a more popular pipe nowadays, everyone chooses this pipe naturally not to forget its advantages and shortcomings, then, what are the advantages of aluminum-plastic composite pipe? What are the disadvantages of aluminum-plastic composite pipes? We've got you covered.

What are the advantages of aluminum-plastic composite pipes?

1. The compressive strength level of aluminum-plastic composite pipe is very high, and the stacking of three raw materials, aluminum alloy profile, hot melt and plastic, makes it integrate into many natural environments, and the high temperature resistance is also relatively good. At the same time, it is safe and non-toxic to use, which happens to be the main reason for its wide use, in the absence of any high fever or strong ultraviolet light environment, the aluminum-plastic composite pipe can be used continuously for 50 years and more.

2. It is very convenient to put in the clamping connector interface to promote the assembly of the aluminum-plastic composite pipe, and the performance of the pipe can be bent at will, and the application of the connector and the elbow can also be minimized when connecting. Especially in some complicated environments, it can easily bypass some columns and beams, thereby reducing the bill of quantities and construction costs.

3. The aluminum-plastic composite pipe has a high-strength welded steel pipe as the frame, which has the effect of improving the high-pressure polyethylene, and the thermal expansion coefficient is small, so the specifications are relatively stable, and the impact and noise caused by water hammer or pressure in the water can be effectively reduced in use.

What are the disadvantages of aluminum-plastic composite pipes?

1. When the bearing force is horizontally, it will greatly endanger the strength of the aluminum-plastic composite pipe, and it is easy to crack when the bearing force is too large, so it is more suitable to be installed on the wall or underground as a concealed pipeline.

2. There is high-density polyethylene in the PPR pipe, and the outside is wrapped in embossed aluminum plate, but the aluminum-plastic composite pipe is also a variety of raw material composite manufacturing, there are problems with different thermal expansion coefficients, and the fusion method also determines that if the bend of the pipeline is too small, it is easy to get rid of the combination of two different raw materials, which will harm the effect of use and the safety of the pipeline.

3. The spare parts of aluminum-plastic composite pipes are mostly all copper, which is more expensive than others, and other more professional construction technologies are very easy to destroy the pipeline, and the cost of repair is very high.

4. The interface mode of air conditioning copper pipe also has electric welding or pipe clamping, etc., and the pipe is divided into two types, one is clamp type, and the other is inverted tooth occlusion and rubber ring sealing. The pipeline was damaged in the subsequent construction process or in the second decoration, and the cost of re-repair was relatively large.

It can be seen that the aluminum-plastic composite pipe has the characteristics of very high compressive strength level, good performance of random bending, and improved effect on high-pressure polyethylene, and has the defect of relatively high cost of repair.
