Is it better to have a copper or aluminum pipe for gas hot water?

Nowadays, many household appliances use copper tubes, and some use aluminum tubes. So some people will have questions, is it better to have copper or aluminum pipes? The following is a detailed introduction to the factors for the selection of copper and aluminum pipes in household appliances.

Aluminum tubes have properties such as low density and soft texture, and cannot be compared with copper tubes in terms of mechanical properties and bending properties. In addition, the density of aluminum and copper is different, and the cross-section is not the same, if the aluminum tube and copper tube are connected, the connection may not be welded firmly, easy to leak fluorine, and may even **. The copper-aluminum connection can easily cause corrosion of aluminum pipes, resulting in poor cooling and heating effects, and even causing air conditioners to not work normally.

The different materials, the life of the aluminum tube is almost half of the copper tube, and the refrigeration effect is relatively worse, because the bending performance is worse than the copper tube, if the consumer wants to move the machine, it is very difficult to bend the aluminum tube again, and basically need to replace the new tube. The use of copper and aluminum pipes in household appliances: from the exhaust port of the compressor to the filter drier, the high-pressure pipe is composed of a condenser, an anti-dew pipe, and a filter, and the high-pressure section is a steel pipe; From the capillary tube to the press of the return pipe called the low-pressure section, the low-pressure section is composed of capillary, evaporator, and return pipe, the capillary tube and the return pipe are made of copper tubes, and the evaporator is generally aluminum tube and iron tube, but since the economic crisis, copper prices have plummeted, and some manufacturers have used copper tube evaporators in order to improve product quality and increase selling points, and refrigerated evaporators are generally installed in the freezer chamber, called the partition type, and the plastic drawers are placed on these partitions, you can take out the drawer, try to see if it is a copper tube, Refrigerated evaporators are generally embedded in the box.

It is better to use a metal hose for the air pipe of a gas water heater. In order to make the metal hose have a long service life, all stainless steel 304 genuine materials are used for production, and the flanges are all made of Shanxi authentic forging materials, which are relatively good materials in terms of strength and sealing. Therefore, it is better to use metal hoses for gas hot water pipes.

One: stainless steel will be better than aluminum-plastic pipes. The strength and corrosion resistance of stainless steel are better, and of course, it is more expensive.

2. Characteristics of stainless steel gas pipe: it has the characteristics of easy installation, reliable connection, corrosion resistance, no gas blockage, good flexibility, long service life, can be bent arbitrarily without deformation, and does not block gas.

The surface soft protective layer material has the characteristics of safer, easier to clean and more beautiful, and the service life of stainless steel threaded metal hose is 8 years. Three: PE gas pipes in China's municipal pipe market, plastic pipes are developing steadily, PE gas pipes, PP-R gas pipes, UPVC gas pipes all occupy a place, among which the strong development momentum of PE pipes is the most eye-catching, and its use is also very extensive.

Thermal conductivity and durability are all copper tubes, which are better, lightweight, smooth and clean, and aluminum tubes are better.

Recommended metal hose for household use, with good sealing and corrosion resistance; Aluminum-plastic pipes are mainly used for direct installation from the back of the table to the home, and are rarely directly connected to the stove.

The strength of the wall of the aluminum-plastic pipe has met the needs, and there is no need to pay attention to the problem of who is strong and who is weak.

The price difference between the ** of aluminum-plastic pipe and the galvanized iron pipe is very large. If the pipe part is more than a few times worse, a single joint is 5 times worse.

Aluminum-plastic pipe**, the quality is very relatively large, and the difference between the two is more than a few pei. Now all gas companies mainly use aluminum-plastic pipes.

Generally, hardware stores can be purchased in these places, but it is recommended that it is best to buy at the manufacturer to reduce costs.

If you are looking for famous brands, Rifeng, Jinde, Meifeng.

But I think the quality of Jinde and Rifeng and Meifeng are similar, but Jinde, Rifeng's advertising is so loud, and the advertising fee is naturally recorded in the ** for consumers to bear. Jinde's competitors are: Taurus, Weixing, Meifeng, Rifeng, Liansu.

If the same quality, I still purchase Meifeng Pipe, mainly looking at the other party's enterprises, quality, and they are one of the largest partners of China Gas Holdings.

Now Jinde and Liansu can't believe it, I have read a series of articles: Jinde aluminum-plastic pipe What to take to make me believe in you, let me feel that the quality of Jinde pipe is too poor, and Liansu now they are calling others to help them produce, and the quality is getting worse and worse.

You can call**to Rifeng, Jinde branch to find**.

Meifeng Management can check their relevant contact information on the Internet.

Gas is now not allowed to use aluminum-plastic pipes.

4 meters or use gas aluminum-plastic pipe, stainless steel bellows are too expensive.

As the name suggests, a gas pipe is a special gas pipe.

Aluminum-plastic pipes can be divided into according to their functions.

Aluminum-plastic composite pipe for ordinary drinking water: white L logo, scope of application: domestic water, condensate, oxygen, compressed air, other chemical liquid pipelines.

Aluminum-plastic composite pipe for high temperature resistance: red R logo, mainly used for hot water and heating piping system with long-term working water temperature of 95.

Aluminum-plastic composite pipe for gas: yellow Q mark, mainly used for transporting natural gas, liquefied gas and gas pipeline systems.

Gas pipes and aluminum-plastic pipes are two different things! The gas pipe represents that the pipe is used for gas, and the gas pipe is also divided into high-pressure pipe and low-pressure pipe, and the household is a low-pressure gas pipe, while the aluminum-plastic pipe represents the material of the pipe, which can pass cold water, hot water, and gas. The gas pipe is divided into hard pipe and hose, hard pipe has white iron pipe, aluminum-plastic pipe, copper pipe, stainless steel pipe, etc., and the hose has rubber cloth, rubber and plastic cloth, rubber, metal corrugated pipe, etc.

The rigid tube is selected according to the person's conditions. And the hose must be purchased several according to the gas company.

Yellow is connected to gas, white is connected to cold water pipes, and red is connected to hot water pipes.
