Description:

Copper tube, non-ferrous metal pipe a kind. Is pressed and drawn seamless pipe. High low temperature intensity. Often used in manufacturing heat transfer equipment (eg condensers, etc). It is also used to assemble low temperature pipeline in oxygen making equipment. Copper pipes with small diameters are often used for conveying pressurized liquids (such as lubricating systems, oil pressure systems, etc.) and for measuring pressure pipes used as instruments. Copper pipes are strong, corrosion resistant, and become the first choice for modern contractors to install piped, heated and refrigerated pipes in all residential commercial buildings. Copper is economic. Because copper pipes are easily machined and connected, they can save material and total cost, stability and reliability when installed Sex, can save repair. Copper is light. For internal threaded tubes of the same inner diameter, copper tubes do not require the thickness of ferrous metal. When installed, copper pipes are less expensive to transport, easier to maintain and less space occupied. Copper can change shape. Because the copper tube can bend and deform, it can often be made into bends and joints, and smooth bending allows the copper tube to bend at any angle. Copper is easy to connect. Copper is safe. No leakage, no combustion, no toxic gas, corrosion resistance. Copper pipe is hard and hard to corrode. It can be used in many environments because of its high temperature and high pressure. In contrast, the disadvantages of many other pipes are obvious, such as galvanized steel pipes used in the past, which are easy to rust, and when used for a short period of time, the running water will become yellowish and the water flow will become smaller. There are also materials that rapidly decrease in strength at high temperatures, creating unsafe conditions when used in hot water pipes, where copper melts at 1083 degrees Celsius, and where the temperature of the hot water system is negligible for copper pipes. Archaeologists found copper pipes in the pyramids of Egypt 4,500 years ago, and still use them.

Features:

the connection of copper pipe is very strong, making it more practical value. Because of the variety of pipes on the market, the interface fittings are mainly copper pipes. Even if some pipes can not use copper fittings, it should have a copper fitting where it is connected to the tap. However, if copper pipe fittings are connected with other pipes, the physical and mechanical properties of hot expansion and contraction vary greatly due to the different materials of pipes and fittings. Therefore, copper pipe and copper fittings connection, the degree of firmness will be greatly enhanced.

Role:

copper tube is widely used than pure iron. 50% copper is electrolyzed to pure copper every year for electrical industry. The copper in question really needs to be very pure and contains more than 99.95% copper. A very small amount of impurities, especially phosphorus, arsenic, aluminum and so on, will greatly reduce the conductivity of copper. Oxygen in copper (which is easy to be mixed with a small amount of oxygen in copper smelting) has a great influence on conductivity. Copper used in electrical industry must be oxygen free copper. In addition, lead, antimony, bismuth and other impurities will make copper crystal can not be combined, resulting in hot brittle, will also affect the processing of pure copper. This kind of pure copper with high purity is usually refined by electrolysis: using pure copper as anode, pure copper as cathode and copper sulfate solution as electrolyte. When the current passes, the impure copper on the anode gradually melts and the pure copper is precipitated on the cathode. Copper so refined; purity up to 99.99. Red copper is a kind of copper which is relatively pure, which can be considered as pure copper. Its electrical conductivity and plasticity are better, but its strength and hardness are worse.
