Tianjin win Cheung copper prices, copper manufacturers: More Power Conference: 13820965368 as manager copper. One kind of non-ferrous metal pipe. Is drawn seamless and repression. Light weight, good thermal conductivity, high temperature strength. Commonly 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 with rugged, corrosion-resistant properties, and become the first choice of modern residential housing contractor in all water pipes, heating, cooling pipe installation. 1, copper is economical. Because brass is easy to process and connect to during installation, you can save materials and total cost, reliability, stability may be omitted maintenance. 2, copper is lightweight. The same internal diameter threaded pipe cutter, the brass does not require the thickness of black metal. Tianjin win when copper prices when Andrew installation, transportation costs brass smaller, easier maintenance and smaller footprint. 3, can change the shape of the copper. Because brass can be bent, deformed, it often can be made and elbow joints, smooth curved brass allowed 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 residence of galvanized steel multi-purpose, easy to rust, there will be a long time without water yellow, water and other smaller problems. Also some material strength at high temperatures will rapidly decrease will have hidden dangers when used in hot water pipes, and the melting point of copper up to 1083 degrees Celsius, the temperature of the hot water system for brass negligible. Archaeologists found inside the pyramids of Egypt dating back 4500 years ago, copper pipes, still can be used. What is the 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. Wherein a significant reduction of titanium, phosphorus, iron, silicon and other electrical conductivity, and cadmium, zinc, etc. are little effect. Copper talking about here, really want to be very pure, more than 99.95% copper job. Very small amount of impurities, especially phosphorus, arsenic, aluminum and the like, will greatly reduce the conductivity of copper. Copper oxygenated (easily when mixed with a small amount of oxygen copper) on a large conductivity for electrical industry generally must be oxygen-free copper. In addition, lead, antimony, bismuth and other impurities can cause copper crystals together, resulting in hot brittle, will also affect the copper processing. This high purity copper, electrolytic method is generally refined: the non-copper (ie blister) as the anode, cathode copper as to * copper solution as electrolyte. When the current through the anode gradually melting impure copper, copper will gradually win Shen Xiang Metal Products Co., Ltd.
