It is used for the connection between copper stranded wire and copper stranded wire or between copper stranded wire and copper conductor. The connection of copper pipe is very strong, which makes it more practical. Because there are many kinds of pipes on the market, the interface fittings are mainly copper pipes. Even if some pipes can not use copper fittings, there should be a copper fitting at the connection with the faucet. However, if the copper pipe fittings are connected with other pipes, due to the different materials of the pipes and fittings, the physical and mechanical properties during thermal expansion and contraction are very different, and the connection firmness will naturally be subject to additional challenges. Therefore, the firmness of the connection between copper pipe and copper fittings will be greatly enhanced. The application of copper tubes is much more extensive than that of pure iron. Every year, 50% of copper is purified into pure copper by electrolysis and used in the electrical industry. The red copper mentioned here must be very pure, containing more than 99.95% copper. A small amount of impurities, especially phosphorus, arsenic and aluminum, will greatly reduce the conductivity of copper. Oxygen in copper (it is easy to mix a small amount of oxygen during copper smelting) has a great impact on the conductivity. Copper used in electrical industry must generally be oxygen-free copper. In addition, impurities such as lead, antimony and bismuth will make the crystallization of copper unable to combine, resulting in heat brittleness, and will also affect the processing of pure copper. This kind of pure copper with high purity is generally refined by electrolysis: impure copper (i.e. crude copper) is used as anode, pure copper is used as cathode, and copper sulfate solution is used as electrolyte. When the current passes, the impure copper on the anode gradually dissolves, and the pure copper gradually precipitates on the cathode.
low temperature and high intensity. Often used in manufacturing heat exchange equipment (such as condensers). It is also used for assembling low-temperature pipelines in oxygen-making equipment. Copper pipes with small diameters are often used to convey pressurized liquids (such as lubrication systems, oil pressure systems, etc.) and pressure measuring pipes used as instruments.
Copper pipes have strong and corrosion-resistant characteristics, and become the first choice for modern contractors to install tap water pipes, heating and refrigeration pipelines in all residential commercial buildings.
1. Copper is economical. Because the copper pipe is easy to process and connect, it can save materials and total cost, stability and reliability during installation, and can save maintenance.
2. Copper is lightweight. For internally threaded tubes of the same internal diameter, copper tubes do not require a thickness of black metal. When installed, copper pipes are less expensive to transport, easier to maintain and occupy less space.
3. Copper can change shape. Because copper pipes can bend and deform, they can often be made into bends and joints. Smooth bending allows copper pipes to bend at any angle.
4. Copper is easily connected.
5. Copper is safe. no leakage, no combustion, no generation of toxic gas and corrosion resistance.
