Copper pipe fittings and welding points for air conditioning refrigeration connection


Air conditioning and refrigeration pipe fittings are pressed or drawn seamless connecting pipes, which are light in weight, good in thermal conductivity, and high in low-temperature strength. They are commonly used in the manufacture of heat exchange equipment such as condensers, and also for the assembly of low-temperature pipelines in oxygen production equipment. Copper pipes with small diameters are commonly used to convey liquids such as pressurized lubrication systems and oil pressure systems or as pressure gauges for instruments.

Air conditioning connecting pipe is lightweight and economical: For twisted threaded pipes with the same inner diameter, the copper pipe does not require the thickness of black metal, and the copper pipe occupies less space during installation. Copper is economical. Due to the easy processing and connection of copper pipes, it can save materials and total costs during installation, ensure stability and reliability, and save maintenance.

The air conditioning connecting pipe has a hard texture, is not easy to corrode, and is resistant to high temperature and high pressure, which can be used in a variety of environments. In comparison, the disadvantages of other pipes are obvious. For example, galvanized steel pipes used in residential buildings in the past are extremely prone to corrosion, and problems such as yellowing of tap water and reduced water flow can occur if they are not used for a long time. 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.

Generally, air conditioning copper pipes are relatively thin, and if too much force is applied, damage can easily occur. It should also be noted that when welding, the copper pipes cannot be faced for a long time, because the copper pipes are relatively thin and will melt in a short time. After welding, the copper pipes need to be cooled with cold water to avoid oxidation problems. The inside of the copper pipes is protected by nitrogen, so there is no oxidation problem, The welding area must not be forcibly pulled, as cracks can easily occur.

When welding copper pipes, it is necessary to prepare things related to welding technology, such as the fuel required for welding with electrodes, the combustion aids required for welding, and so on. After everything is ready, the operation can be carried out. Do not find any defects during the welding process, as there is no way to ensure successful welding. When operating gas cylinders, it is necessary to keep the gas cylinders upright and the distance between oxygen cylinders and natural gas cylinders, Also, the distance to the open flame must be more than five meters in order to ensure safety. The connection methods of welding torches and gas cylinders should also be checked for correctness, and relative distances should be maintained. It is also important for everyone to wear protective glasses during operation. During welding, it is necessary to ensure smooth ventilation, so as to ensure the safety of the welding environment and avoid accidents.
