Choosing copper pipes to install the air conditioning system. Dubai, UAE

AC copper pipes are rightfully considered a key element in the installation of an air conditioning system of any complexity. As a rule, it is necessary to use two copper tubes with different diameters: one tube is used to move between the internal and external blocks of the cooling compound (freon as usual) in the liquid state, and the other in the gaseous state.

Technical specifications for copper pipes

The main indicators for the selection of the required products are the diameters of ac pipes for air conditioners. The rate of circulation of the refrigerant through the system depends on their value. In addition, a well-defined cross-section will significantly reduce pressure losses in units that cool the air.


Heat conductivity is crucial in conduction cooling. When using the matter of low heat resistance, the system can’t quickly get rid of extra heat and, thus, becomes inefficient.

A copper pipe can boast with one of the highest heat conductivity among other metals. Its main rival is silver but the last one is a very expensive metal, which alone makes it no one competitor on the air conditioning market.

With Al Farid Wood and Metal Trading Company, we will discuss these properties to understand why they make a copper pipe the only choice for air conditioning.

Copper tubes have a diameter of 0.6 to 26.7 cm. In climate technology, conditioner copper pipes are usually used with a size of 19.05, 6.35; 12.7; 9.52 and 15.88 mm (which corresponds to ¾, ¼, ½, ⅜ and ⅝ inches). The standard minimum value of the product wall thickness for climatic equipment is 0.7 mm, however, in the general case, the parameter can vary from half a millimeter to 0.3 cm.

 During the installation of air conditioners, seamless copper pipes are used, which are interconnected using special fittings. The dimensions of ac copper tubes are directly dependent on the performance of the cooling system that is supposed to be mounted.

Corrosion resistance

Corrosion resistance stands for the matter ability to stay against rust. To clarify, it determines the pipe lifespan. Take a tube of a low corrosion resistance metal, and you will soon need to replace it.

Copper is highly corrosion resistant due to its unordinary feature. When contacting the oxygen, there appears an oxide coating that protects the metal from corrosion. Thus, when you use, for example, AC Copper Pipe size ⅜ for your HVAC system, you can be sure the pipe will last for at least 50 years.
