3P air -conditioned copper aluminum connecting tube insulation pipe
Copper aluminum air -conditioning connecting tube is a new type of
air -conditioning connecting tube. It is made of two sections of
copper round tubes and aluminum tubes through accurate welding
technology. The design of this connection tube fully considers the
actual needs of air conditioning equipment, and has the following
characteristics and advantages:
First of all, the copper round tube of the copper aluminum
connecting tube is perfectly matched with the brass parts of the
inside and outside air -conditioning machine, which can achieve
close connection. This connection method effectively prevents the
electrochemical reactions between aluminum round tubes and bronze
parts, thereby extending the service life of the connecting tube,
and ensuring the sealing of the connection tube, which provides a
reliable reliability for the normal operation of the air
conditioner. Guarantee.
Secondly, the aluminum tube of the copper circular aluminum
connecting pipe is light and the price is affordable. This makes
the copper aluminum connecting tube more convenient and fast during
transportation and installation, and can also reduce transportation
costs and labor intensity. In addition, the price of aluminum
circular pipes is more affordable and can save consumers a certain
cost. More importantly, aluminum is a recyclable metal, which does
not cause waste of resources and environmental pollution.
Therefore, the use of copper and aluminum connection pipes is more
environmentally friendly.
Finally, the overall thermal conductivity of copper and aluminum
connectors is better than pure aluminum round tube. This is due to
the excellent thermal conductivity of the copper round tube, so
that the connector can effectively maintain the internal
temperature, reduce the loss of the refrigerant during
transportation, and thereby improving the cooling and thermal heat
of the air conditioner. This is of great significance for improving
the operating efficiency of air conditioners, reducing energy
consumption and improving user experience.
(1) The welding point shows a model of flawlessness. The air pores, cracks, slag, burrs, and burns are none of them. There is no melting produced. The oxide film is eliminated. The holes with a diameter of 6.3 mm are strictly controlled above 3.0 mm.
(2) For gas tightness, we proved that products under more than 4.0MPa have not leaked after 5 minutes, showing excellent closed performance.
(3) In order to further prove the stability and tolerance of the product, we gradually increase the pressure to 13MPa and maintain it for one minute. As a result, there was no crack, which fully confirmed its durability and strength.
(4) The results of the bending test show that the samples with twice the nominal diameter of the pipeline do not produce folds and cracks after bending 180 degrees, which fully indicates that the product has good plasticity and crack resistance.
(5) In the tensile strength test, the product's tensile strength is within the range of 65-118MPa, the tolerance part is on the side of the aluminum tube, and the weld is above 10mm, which once again proves its excellent welding quality and strength.
(6) In terms of KTG, the contraction is excellent. The sealing accessories have been completely melted and wrapped in the copper aluminum joints. After fastening, it cannot be rotated, which fully ensures its sealing performance and service life.

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.
