High Quality Copper-Aluminum Connection Pipe for Welding Pores and Cracks

Detailed explanation of technical standards for copper-aluminum connecting pipes:
1. Quality requirements for welding points:
The welding joints of copper and aluminum connecting pipes must be free of defects such as pores, cracks, slag, burrs and burns. During the welding process, the two metals, copper and aluminum, must be completely fused with no obvious oxide film. Special attention should be paid to the reduction of the plug hole should be controlled within the range of Φ6.3 hole greater than 3.0mm to ensure the sealing performance and service life of the connecting pipe.
2. Air tightness requirements:
The air tightness requirements of copper-aluminum connecting pipes are very strict, and a high-pressure test of 4.0MPa is required for 5 minutes to confirm the sealing performance of the connecting pipes. During the inspection process, the connecting pipe must not have any leakage to ensure its stability and reliability for long-term use.
3. Pressure resistance performance requirements:
After passing the air tightness inspection, the pressure needs to be slowly increased to 13MPa and maintained for 1 minute. During this process, the copper-aluminum connecting pipe cannot have any cracks or damage to prove its excellent pressure resistance.
4. Bending performance requirements:
The bending performance requirements of copper-aluminum connecting pipes are very high. After the sample is bent into a bending core that is twice the nominal diameter of the pipe, after bending 180 degrees, the pipe must not produce wrinkles or cracks. This requirement ensures that the connecting pipe can adapt to various complex environments and conditions during installation and use.
5. Tensile strength requirements:
The tensile strength of the copper-aluminum connecting pipe is required to be between 65-118mpa. This is to ensure that the connecting pipe can withstand a certain external load during use. When the tensile part is located on the side of the aluminum pipe, the length of the weld should be greater than 10mm to ensure the stability and service life of the connecting pipe.
6. Sealing performance requirements:
The sealing performance requirements of copper-aluminum connecting pipes are very high. KTG shrinks well, and the sealing accessories have melted and are completely wrapped in the copper-aluminum joints, and the seal cannot rotate. This sealing performance can effectively prevent the leakage of liquid or gas, thereby ensuring the reliability and safety of the connecting pipe in various application scenarios.
To sum up, the technical standards of copper-aluminum connecting pipes involve many aspects, including the quality of welding points, air tightness, pressure resistance, bending performance, tensile strength and sealing performance. These standards ensure that copper-aluminum connecting pipes have excellent performance and reliability and are suitable for various application scenarios.

Features:

Copper-aluminum air conditioning connecting pipe is an innovative air conditioning accessory that combines the advantages of copper pipes and aluminum pipes and is made through advanced welding technology. This kind of connecting pipe not only has high durability and safety, but also can reduce costs and environmental impact, while improving the cooling and heating efficiency of air conditioners.
First of all, the copper pipe part of the copper-aluminum air-conditioning connecting pipe can be perfectly connected with the brass parts of the internal and external units of the air conditioner, avoiding the problem of electrochemical corrosion that may occur between the aluminum pipe and the brass parts. Due to the different electrochemical properties of copper and aluminum, the copper-aluminum connecting pipe may undergo electrochemical corrosion in a humid environment, causing damage to the connecting pipe. Therefore, using copper pipe parts can effectively avoid this problem and improve the durability and safety of the connecting pipe.
Secondly, the aluminum pipe part of the copper-aluminum air conditioning connecting pipe can reduce the weight and cost of the connecting pipe. Aluminum is a relatively light metal, so using aluminum pipes can reduce the weight of the connecting pipes, making installation and transportation easier. In addition, the production cost of aluminum pipes is relatively low, so using aluminum pipes can reduce the cost of connecting pipes and improve production efficiency.
In addition, copper-aluminum air conditioning connecting pipes also have environmental advantages. Aluminum is a renewable metal, and its use will not lead to resource shortages and environmental damage. In contrast, some pure metallic materials, such as copper, have limited resources and over-exploitation can cause environmental damage. Therefore, the use of copper-aluminum connecting pipes can reduce the impact on the environment and meet the requirements of sustainable development.
Finally, the copper-aluminum air conditioning connecting pipe as a whole is more insulating than pure aluminum pipes. Since the thermal conductivity of copper pipes is higher than that of aluminum pipes, the thermal insulation performance of copper-aluminum connecting pipes is better. This feature can effectively maintain the temperature inside the connecting pipe, reduce the loss of refrigerant during transportation, and improve the cooling and heating efficiency of the air conditioner. This not only reduces energy consumption but also reduces environmental impact.
In short, the copper-aluminum air conditioning connecting pipe is an innovative air conditioning accessory that combines the advantages of copper pipes and aluminum pipes, with high durability and safety, lower cost and environmental impact, and better thermal insulation performance . These characteristics make copper-aluminum air conditioning connecting pipe an excellent air conditioning accessory, widely used in household, commercial and industrial air conditioning systems.
