Copper-Aluminum Air-Conditioning Connection Pipe: Durable, Safe & Efficient
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. The
two metals, copper and aluminum, should be completely fused during
the welding process, with no obvious oxide film. In addition, the
size of the plug hole should comply with the standard and cannot be
significantly reduced. For example, for a Φ6.3 hole, the size
should be greater than 3.0mm.
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 determine whether the connecting pipes are leaking.
This strict testing ensures the stability and reliability of the
connecting pipe in high-pressure environments.
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 to test
the pressure resistance of the copper-aluminum connecting pipe.
During this process, the copper-aluminum connecting pipe cannot
have any cracks to ensure its stability in high-pressure
environments.
4. Bending performance requirements:
The bending performance requirements of copper-aluminum connecting
pipes are very high. The sample needs to be bent into a bending
core that is twice the nominal diameter of the pipe, and then
inspected after bending 180 degrees. Pipes should be free of
wrinkles and cracks to ensure their stability and reliability under
bending.
5. Tensile strength requirements:
The tensile strength requirement of copper-aluminum connecting pipe
is between 65-118mpa. In the tensile test, the tensile part should
be on the side of the aluminum pipe, and the length of the weld
should be more than 10mm. This ensures the stability and
reliability of the connecting pipe when subjected to tension.
6. Sealing performance requirements:
The sealing performance requirements of copper-aluminum connecting
pipes are very high. The KTG shrinkage should be good and the
sealing fittings have been melted and completely wrapped in the
copper-aluminum joint. In the sealed state, the seal cannot rotate
to ensure the sealing and stability of the connecting pipe.
The copper-aluminum air-conditioning connecting pipe is an
innovative air-conditioning connecting pipe. It is composed of a
section of copper pipe and a section of aluminum pipe tightly
combined through advanced welding technology. This unique
combination gives the copper-aluminum air conditioning connecting
pipe a series of outstanding features and advantages.
First of all, the copper pipe part of the copper-aluminum
connecting pipe can be perfectly connected with the brass parts of
the air conditioner's internal and external units, ensuring the
stability and durability of the connection. In addition, due to the
high chemical stability of copper, the risk of electrochemical
corrosion between aluminum tubes and brass parts can be effectively
avoided. In this way, users can use this connecting pipe with more
confidence without worrying about leakage or damage, thereby
improving the durability and safety of the connecting pipe.
Secondly, the aluminum pipe part of the copper-aluminum connecting
pipe has the advantage of reducing the weight and cost of the
connecting pipe. Aluminum is a lightweight, high-strength metal
material. Compared with traditional pure copper connecting pipes,
copper-aluminum connecting pipes are significantly lighter in
weight, making installation and transportation easier. In addition,
the cost of aluminum pipes is also low, which allows the
manufacturing cost of copper-aluminum air conditioning connecting
pipes to be effectively controlled, saving unnecessary expenses for
users.
More importantly, the environmental impact of copper-aluminum
connecting pipes is also reduced. Aluminum is a renewable metal
material. Through reasonable recycling and reuse, effective
recycling of resources can be achieved. Compared with traditional
pure copper connecting pipes, copper-aluminum connecting pipes have
a higher recycling rate and will not cause resource shortages and
environmental damage. This is in line with the current society's
pursuit of sustainable development and provides users with a more
environmentally friendly air conditioning connecting pipe solution.
Finally, the overall thermal insulation performance of
copper-aluminum air conditioning connecting pipes is better than
that of pure aluminum pipes. Due to the low thermal conductivity of
the copper tube, it can effectively prevent the transfer of heat
and keep the internal temperature of the connecting tube stable. In
this way, the loss of refrigerant during the transportation process
is reduced, and the cooling and heating efficiency of the air
conditioner is improved. At the same time, this also means that the
use of this connecting pipe can reduce energy consumption and
carbon emissions, making a positive contribution to environmental
protection.
To sum up, the copper-aluminum air conditioning connecting pipe
combines excellent performance, environmental protection and
economic advantages with its innovative design and technology. It
provides users with an efficient, safe and environmentally friendly
air conditioning connecting pipe solution, adapting to the needs of
modern society for sustainable development.

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.
