1/2 3/4 Copper Round Pipe AC Air Conditioner Pancake Copper Tubing
Copper pipes combine the advantages of metal pipes and non-metal
pipes. It is harder than plastic pipes and has the high strength of
ordinary metals (the strength of cold-drawn copper pipes is
equivalent to that of steel pipes with the same wall thickness); it
is more flexible than ordinary metals, has good toughness and high
ductility, and has excellent anti-vibration and Impact and frost
Copper tubes can withstand extremely cold and extremely hot
temperatures, with a wide range of applications from -196 degrees
to 250 degrees, and adapt to drastic changes in temperature (-high
temperature-low temperature-high temperature-), and the performance
will not change due to long-term use and drastic temperature
changes And reduce, will not produce aging phenomenon. This is
beyond the reach of ordinary pipes.
The linear expansion coefficient of the copper pipe is very small,
which is 1/10 of that of the plastic pipe, and it can resist
fatigue. When the temperature changes, it will not cause excessive
thermal expansion and contraction, which will cause stress fatigue
These characteristics make the application of copper pipes in cold
regions extremely advantageous. In severe cold areas, the
temperature difference between morning and evening is large, and
ordinary pipes have a large linear expansion coefficient and low
strength, and are prone to stress fatigue cracks due to thermal
expansion and contraction. Some claim that it is not brittle at -20
degrees, but in fact it cannot withstand working pressure, and its
service life is very short, which has no practical significance.
Although insulation measures can be used, it is inevitable to
encounter low temperatures during transportation, storage and
installation. The performance of the tube is the same at -183
degrees and normal temperature.
