Copper Aluminum AC Connection Pipe Thermal Conductivity & Corrosion Resistance

Copper-Aluminum Air Conditioning Connecting Pipe: Thermal Conductivity & Corrosion Resistance

Copper-aluminum air conditioning connecting pipe is an innovative, practical and environmentally friendly air conditioning accessory. It is made of a section of copper round tube and a section of aluminum round tube through high-precision welding technology. It not only combines the excellent thermal conductivity and corrosion resistance of copper round tube, but also combines the lightness, cheapness and environmental protection characteristics of aluminum round tube. The following are the characteristics and advantages of copper-aluminum air conditioning connecting pipes:
First of all, the copper round tube part of the copper-aluminum connecting tube perfectly matches the brass parts of the internal and external units of the air conditioner, enabling a tight connection. This connection method effectively prevents the possible electrochemical reaction between the aluminum round tube and the brass parts, thereby extending the service life of the connecting tube, ensuring the sealing of the connecting tube, and providing reliable operation for the normal operation of the air conditioner. protection.

Secondly, the aluminum round tube part of the copper-aluminum connecting tube is lighter than the pure copper round tube. This feature of aluminum round pipes makes installation, transportation and storage more convenient and reduces related costs. At the same time, the price of aluminum round pipes is also more affordable, saving consumers purchase costs. More importantly, aluminum is a recyclable metal that can be used repeatedly without causing resource waste or environmental pollution, and is in line with the current green and environmentally friendly social development trend.

Finally, the overall thermal conductivity of copper-aluminum connecting tubes is better than that of pure aluminum tubes. Since the thermal conductivity of copper is higher than that of aluminum, the thermal conductivity of the copper-aluminum connecting tube is improved. This feature plays an important role in maintaining temperature stability inside the connecting pipe, thereby reducing the loss of refrigerant during transportation and improving the cooling and heating effects of the air conditioner. This plays a key role in improving the operating efficiency of air conditioners, saving energy and reducing consumption, and extending the service life of air conditioners.

Features :

There are no pores, cracks, slag, burrs and burns, no fusion, no obvious oxide film, no plugged holes, and there is no significant reduction in the number of holes in the sample with a diameter greater than 3.0mm.

In the air tightness test where the pressure reached 4.0MPa and was maintained for 5 minutes, this product was able to withstand the pressure and achieve zero leakage, proving that its sealing performance is excellent and stable.
After the pressure test is completed, the product can be gradually increased to 13MPa and maintained in a stable state. This strength ensures that there will be no cracks during this stage.

After the bending test, it can be seen that the pipe sample is bent into a bending core equal to the nominal diameter of the pipe. During this process, after the sample reaches a 180-degree bending radius, the pipe has no obvious wrinkles and no cracks, which fully reflects the material. flexibility and bending resistance.

The tensile strength test results show that the tensile strength of the product is in the range of 65-118 MPa, the tensile force part is located on one side of the aluminum pipe, and the weld distance reaches more than 10mm. These data prove that the material has high strength and good welding performance. .

In terms of KTG, the shrinkage of the product is good, and the sealing accessories have been melted and wrapped around the copper-aluminum joints, forming a stable sealing effect and ensuring the stability and sealing performance of the connection.

FAQ.:

Q1: aluminum alloy pipe compared with copper pipe, advantages and disadvantages?

A1: Aluminum pipe cost low ductility, but easy to corrosion. Copper pipes have good thermal conductivity and corrosion resistance, but the installation, preservation and transportation are not easy and the cost is high.

Q2: What should be noted in the installation of the air conditioning connection pipe?

A2: The alloy pipe is easy to install, but the link of copper and aluminum after a long time of chemical changes, will cause electrocouple corrosion.

Q3: How to deal with the corrosion problem?

A3: Our products use special corrosion resistant alloy, and the corrosion resistance effect is greatly improved compared with ordinary aluminum alloy. The corrosion resistance experiment is> 1000 hours, which greatly improves the service life of the product.

Q 4: What state and performance of aluminum pipe and aluminum alloy pipe can be produced?

A 4: It can produce performance products from hard state to soft state and interval.
