First, the price of aluminum-plastic composite pipe
Aluminum-plastic composite pipe is the earliest water supply pipe to replace cast iron pipe. Its basic composition should be five layers, followed by plastic, hot melt adhesive, aluminum alloy, hot melt adhesive and plastic from inside to outside. At present, the leading area of aluminum-plastic pipe quality in China: Foshan. Domestic famous brands include Rifeng, Fengtai and meifeng.
Aluminum-plastic composite pipe has good thermal insulation performance, and the inner and outer walls are not easy to corrode. Because the inner wall is smooth, the resistance to the fluid is very small. And because it can be bent at will, it is convenient to install and construct. As a water supply pipe, aluminum-plastic composite pipe has enough strength.
Excessive lateral stress will affect the strength, so it is suitable to construct open pipe or bury it in the wall or even underground. (Aluminum-plastic composite pipe can also be buried underground. For example, the pipe used for floor heating is aluminum-plastic composite pipe. The connection of aluminum-plastic composite pipe is sleeve-type (or compression-type), so first of all, it is necessary to pass strict pressure test during construction to check whether the connection is firm. The second is to prevent frequent vibration and make the fixture loose. Third, there should be enough installation in the length direction to avoid pulling off.
First, the price gap of pipelines with different wall thicknesses is large. The market price of commonly used aluminum-plastic pipes with a diameter of 20 mm in the market is about 18 yuan with a wall thickness of 2 mm, while the market price of pipes with a diameter of 3.2 mm is about expensive 1 times. Thick-walled pipes are much better in heat preservation, impact resistance and aging resistance, but the price is also much more expensive.
Second, the prices of pipelines with different diameters vary greatly. At present, the commonly used pipelines are 16 mm, 20 mm and 25 mm, and the prices vary greatly. The thicker the pipe, the more expensive it is. In order to reduce costs, many companies will try to choose thin tubes. Under the same conditions, the thinner the pipeline, the greater the water resistance. Although the heating system can also be hot, the effect is different.
Third, different brands have different prices. The processing technology and raw material prices of each family are also very different. There are many small workshops whose products are several times different from those of regular manufacturers.

Second, the aluminum-plastic composite pipe specifications
There are three kinds of aluminum-plastic composite pipes on the market:
1, PE/AL/PE (polyethylene/aluminum/polyethylene);
2. Polyethylene/aluminum /PEX (polyethylene/aluminum/crosslinked polyethylene);
3. PEX/ aluminum /PEX (crosslinked polyethylene/aluminum/crosslinked? Polyethylene).
In view of the limited information available in the market, the above contents include product specifications, advantages and characteristics, price examples, price determinants, etc. Furthermore, we also analyze it from the perspective of consumers, and list the knowledge content worthy of reference and reference in the actual purchase operation process for relevant people to analyze. I believe that everyone can ensure the expected effect as much as possible after learning.
