Copper tubes (also known as copper tubes) are often installed in water pipes, heating, and refrigeration pipelines. The tubes are hard in texture, not easy to corrode, and are resistant to high temperatures and high pressures. , can be used in a variety of environments. Copper pipes combine the advantages of metal and non-metal pipes. They are the first among copper pipes in hot and cold water systems and are the best connecting pipes. Copper pipes are fire-resistant and heat-resistant. They can still maintain their shape and strength under high temperatures and will not age. Copper pipes are strong and corrosion-resistant, and have become the first choice for modern contractors to install water pipes, heating, and cooling pipes in all residential commercial buildings. Copper pipes combine many advantages. They are strong, have the high strength of ordinary metals, and are also stronger than ordinary metals. Generally, metal is easy to bend, twist, crack, and break, and has certain resistance to frost heaving and impact. Therefore, once the copper water pipes in the water supply system of the building are installed, they are safe and reliable to use, and even do not require maintenance and upkeep. Copper pipes are hard, not prone to corrosion, are resistant to high temperatures and high pressures, and can be used in a variety of environments. In comparison, the shortcomings of many other pipes are obvious. For example, galvanized steel pipes, which were commonly used in residential buildings in the past, are easily corroded. After a short period of use, the tap water will turn yellow and the water flow will become smaller. The strength of some materials will rapidly decrease at high temperatures, which may cause unsafe risks when used in hot water pipes. The melting point of copper is as high as 10 degrees Celsius, and the temperature of the hot water system is insignificant to copper pipes. Archaeologists have discovered copper water pipes in the Egyptian pyramids from 20 years ago that are still in use today.
Copper has stable chemical properties, integrating cold resistance, heat resistance, pressure resistance, corrosion resistance and fire resistance (the melting point of copper is as high as 100 degrees Celsius), and can be used in different environments for a long time. The service life of copper pipes can be as long as the life of the building, or even longer. For example, the copper plumbing fittings installed in the Peking Union Medical College Hospital in the 1900s have lasted for many years and are still performing well today. It can be seen that copper pipes are pipes that have been fully tested by more than a hundred years of time and practical experience. 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 easier to bend than ordinary metals, has good toughness and high ductility, and has excellent vibration and impact resistance. And anti-frost heave performance, the copper pipe can withstand extremely cold and extremely hot temperatures, has a wide application range from degrees to degrees, and can adapt to drastic changes in temperature (high temperature, low temperature and high temperature), and its performance will not be reduced due to long-term use and drastic changes in temperature. , no aging phenomenon will occur. This is beyond the reach of ordinary pipes.
Commonly used copper tubes can be divided into the following types: copper condenser tubes, crystallizer copper tubes, air conditioning copper tubes, various extruded, drawn (reverse extrusion) copper tubes, iron-nickel copper tubes, brass Tubes, bronze tubes, cupronickel tubes, beryllium copper tubes, tungsten copper tubes, phosphor bronze tubes, aluminum bronze tubes, tin bronze tubes, imported red copper tubes and other thin-walled copper tubes, capillary copper tubes, hardware copper tubes, special-shaped copper tubes , small copper tubes, pen copper tubes, and pen copper tubes. According to user needs, square and rectangular crystallized copper tubes, square copper tubes, eccentric copper tubes, etc. are processed and produced according to drawings.
