Copper Tube Properties

Copper pipes, commonly used in tap water pipes, heating and cooling pipes, can be used in different environments. The copper tube combines the advantages of metal and non-metal tube, and it is the best connecting pipe in the hot and cold water. The copper tube is refractory and heat resistant, retains its shape and strength at high temperatures, and does not age.

The pressure resistance of copper pipes is several times or even several times that of plastic pipes and aluminum-plastic pipes. It can withstand the highest water pressure in today's buildings. In the hot water environment, the pressure capacity of the plastic pipe is significantly reduced with the extension of the service life, and the mechanical properties of the copper pipe remain unchanged in all the hot temperature ranges, so the pressure resistance is not reduced, There is no aging phenomenon.

The linear expansion coefficient of the copper tube is very small, which is 1/10 of the plastic tube, and will not cause stress fatigue cracking due to excessive thermal expansion and contraction.


The strength of the copper tube is greater, and the outer diameter is smaller under the requirement of the effective inner diameter, which is more suitable for burying.

Light weight, good thermal conductivity and high low temperature strength. Often used in the manufacture of heat exchange equipment. It is also used in the assembly of cryogenic piping in oxygen plants. Copper tubes with small diameters are often used to transport pressurized liquids and pressure tubes used as meters.

The copper tube has strong and corrosion-resistant properties, and it is the first choice for modern contractors to install tap water pipes, heating and refrigeration pipes in all residential commercial houses.

The copper tube has many advantages in one: it is strong and has the high strength of general metal. At the same time, it is more flexible than ordinary metal, easy to twist, not easy to crack, not easy to break, and has certain anti-frozen and impact resistance, so it is in the building. Once installed, the copper water pipes in the water supply system are safe and reliable to use, even without maintenance and maintenance.


Commonly used copper tubes can be divided into the following types:

Copper condensing tube, crystallizer copper tube, air conditioning copper tube, various extrusion, drawn copper tube, iron white copper tube, brass tube, bronze tube, white copper tube, therefore copper tube, tungsten copper tube, phosphor bronze Tube, aluminum bronze tube, tin bronze tube, imported red copper tube, etc.

Thin-walled copper tube, capillary copper tube, hardware copper tube, shaped copper tube, small copper tube, pen copper tube, pen copper tube, etc.

Rectangular crystallizer copper tube, and d-type copper tube, eccentric copper tube, etc.
