Copper. One kind of non-ferrous metal pipe. It is drawn seamless and repression. Light weight, good thermal conductivity, high temperature strength. Used in the manufacture of heat transfer equipment (such as condensers, etc.). Oxygen is also used for low temperature piping assembly equipment. Small diameter copper pipe used for conveying liquid under pressure (such as lubrication system, hydraulic system, etc.) and used as instruments of pressure measuring tube. Brass has strong, corrosion-resistant properties, and become first choice for modern residential housing contractor in all water pipes, heating, cooling pipe installation. 1, copper is economical. Since brass is easy to process and connection to the installation, you can save materials and total cost, stability, reliability can be omitted maintenance. 2, copper is lightweight. The same inner diameter of the threaded pipe cutter, the brass does not require thickness of the black metal. Tianjin Xiang win when copper prices when installation, transportation costs brass smaller, easier maintenance and smaller footprint. 3, the shape of the copper can be changed. Because the brass can be bent, deformed, it often can be made into bends and fittings, brass allow smooth bending at any angle bend. 4, copper is easily connected. 5, copper is safe. No leakage, no combustion, no toxic gases, corrosion-resistant. Brass hard, difficult to corrosion, and high temperature, high pressure, can be used in a variety of environments. In contrast, many of the shortcomings of other pipes is obvious, such as the last residential multi-galvanized steel, easy to rust, not a long time there will be running water yellow, water and other smaller issues. Some material strength at high temperatures will rapidly decrease will have hidden dangers when used for hot water pipes, and the copper melting point of 1083 degrees Celsius, the temperature of the hot water system of copper pipes insignificant. Archaeologists found within pyramids of Egypt dating back 4500 years ago, copper pipes, still can use. What is T2 copper: copper copper grades suitable for manufacturing only (T1, T2, TU2, TP2,410A). Copper trace impurities have a serious impact on the electrical conductivity, thermal conductivity of copper. Which significantly reduces titanium, phosphorus, iron, silicon and other electrical conductivity, and cadmium, and zinc is little effect. Here, the copper, really have to be very pure copper over 99.95% of the job. A very small amount of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. Copper oxygenated (easily mixed with a small amount of oxygen when copper) on a large conductivity for electrical industry generally must be oxygen-free copper. In addition, lead, antimony, bismuth and other impurities in crystals of copper will not combine to cause heat brittle, will also affect copper processing. This high purity copper, general electrolysis refining: the non-copper (ie blister) as the anode, copper as the cathode, with * copper solution as electrolyte. When the current through the impure copper anode gradually melting, copper will gradually sink Cheung Metal Products Co., Ltd. Tianjin win national sales
