Air conditioning and refrigeration fittings are pressed or drawn seamless connecting tubes, light weight, good thermal conductivity, high strength at low temperatures, commonly used in such as condensers and other manufacturing heat exchangers, but also used in oxygen equipment for the assembly of low-temperature piping. Small diameter copper tubes are commonly used in the delivery of pressure lubrication system, oil pressure system and other liquids or used as a meter pressure measurement tube.
Air conditioning connection pipe lightweight and economical: for the same inner diameter of the stranded threaded pipe, the purple copper pipe does not require the thickness of ferrous metal, in the installation of the purple copper pipe occupies less space.
Because copper pipe is easy to process and connect, so that when it is installed, it can save materials and total cost, stability can be reliable, can save maintenance.
Air conditioning connection pipe is hard: not easy to corrode, and high temperature and high pressure resistance, can be used in a variety of environments. In contrast, the shortcomings of other pipes are obvious, such as galvanized steel pipes used in the past residential, very easy to corrode, the use of a short period of time there will be yellowing of the tap water, the water flow becomes smaller and other problems. The melting point of copper is as high as 1083 degrees Celsius, and the temperature of the hot water system is insignificant for copper pipes.
General air conditioning copper pipe is relatively thin, if the force is too large, it is easy to damage the situation, but also should pay attention to the welding can not be a long time against the copper pipe, because the copper pipe is relatively thin, in a very short period of time inside will melt, welding copper pipe also need to cool with cold water, so that oxidation will not occur, the copper pipe is protected by the nitrogen inside, so there will be no oxidation, welding of the The place must not be hard to break, it is easy to crack.
Welding copper pipe, must be prepared and welding technology-related things, such as welding rod welding need to use fuel, welding needs to be used to the flux, etc., things ready after the operation, do not find in the process of welding inside the lack of this lack of that, so there is no way to make the welding successful, in the operation of the gas cylinder must be to keep the gas cylinder upright, oxygen cylinders and natural gas cylinders, and the distance to open flames must be five to five meters away. To the distance of the open flame must be more than five meters, so as to ensure safety, welding torch and gas cylinder connection method should also check whether it is correct, but also need to maintain a relative distance, everyone in the operation of the time to wear good protective glasses is also very important, the welding must ensure that the ventilation is smooth, so as to make the welding environment is safe, and is not prone to accidents.
