Lightweight Copper-Aluminum AC Connection Pipe with High Efficiency:
The copper-aluminum air-conditioning connecting pipe is an innovative air-conditioning connecting pipe. It is composed of a section of copper round pipe and a section of aluminum round pipe tightly combined through advanced welding technology. This unique combination not only gives the copper-aluminum air-conditioning connecting pipe excellent durability and safety, but also has the characteristics of lightweight, environmental protection and high efficiency, making it unique in the air-conditioning industry.
The copper tube part of the copper-aluminum connecting tube is made
of high-quality copper material. It can be perfectly connected with
the brass parts of the internal and external units of the air
conditioner, avoiding the risk of electrochemical corrosion that
may occur between the aluminum round tube and the brass parts. This
carefully designed connection method greatly improves the
durability and safety of the entire connecting pipe, so you don't
have to worry about potential maintenance problems during use.
As for the aluminum pipe part of the copper-aluminum connecting
pipe, it not only reduces the weight of the connecting pipe,
optimizes the cost, but also has environmental protection
advantages. Aluminum is a recyclable metal, so using aluminum round
tubes can avoid resource shortages while not causing damage to the
environment. This carefully selected material and design fully
reflects the pursuit of green, environmentally friendly and
sustainable development goals of copper-aluminum air conditioning
connecting pipes.
The overall copper-aluminum connecting pipe is more insulated than
pure aluminum pipe. This is because it uses advanced welding
technology to form a uniform transition layer between the copper
round pipe and the aluminum round pipe, effectively reducing the
loss of heat conduction. This efficient thermal insulation
performance can maintain stable temperature inside the connecting
pipe, thereby reducing the loss of refrigerant during
transportation and improving the cooling and heating efficiency of
the air conditioner. This design helps reduce energy consumption
and meets the needs of modern society for energy conservation and
emission reduction.
To sum up, the copper-aluminum air conditioning connecting pipe has
become a leader in the field of air conditioning with its
innovative design concept and exquisite craftsmanship. Its
emergence not only improves the performance and efficiency of
connecting pipes, but also promotes the progress and development of
the entire industry.
1. Ultra-long service life: The outer surface of the
copper-aluminum connecting pipe is made of cross-linked
polyethylene for anti-corrosion treatment to ensure that the
corrosion of the aluminum pipe by water and humid air is
effectively controlled and its service life is guaranteed to be
more than 20 years.
2. High cost-effectiveness: There will be no oxidation and
corrosion of knots and other problems between the copper and
aluminum connecting pipe ends and the valve, thus avoiding the
increase in costs caused by these problems.
3. High cleanliness: Since there is no need for welding between the
copper tubes and the aluminum tubes, they are connected through
cold connections, which avoids the generation of surface oxides
that may be caused by high-temperature welding, so the cooling tube
quality can be achieved without additional processing. Cleaning
requirements
4. Improve the energy efficiency of air conditioners:
Copper-aluminum connecting pipes have excellent thermal insulation
properties, which can effectively reduce energy waste and further
improve the thermal insulation performance of connecting pipes,
thereby improving the energy efficiency of air conditioners.
5. Equivalent to the burst pressure of copper pipes: The burst
pressure of copper-aluminum connecting pipes is exactly the same as
the allowed burst pressure of copper connecting pipes. The design
pressures of both are 13.0Mpa, indicating that copper-aluminum
connecting pipes also perform well in high-pressure environments.
6. Easy to install and move: Since the hardness of aluminum is
lower than brass, the copper tube part of the copper-aluminum
connecting tube is designed to be 1.5 times thicker than the brass
tube wall, making it more convenient to install and move.
Generally speaking, copper-aluminum connecting pipes have many
advantages such as long service life, low cost, high cleanliness,
high efficiency, high safety, and easy installation.

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.
