Purple copper pipe is a kind of non-ferrous metal pipe, which is pressed and drawn seamless pipe. Compared with the general galvanized steel pipe, copper pipe is not easy to rust and corrosion, and there will be no problems such as yellowing of tap water and water flow becoming smaller after a long time of use. There are also some materials in the high temperature of the strength will be rapidly reduced, used for hot water pipe will produce unsafe hidden danger, and the melting point of copper up to 1083 degrees Celsius, hot water system temperature on the copper pipe is negligible. Archaeologists have found copper plumbing in Egyptian pyramids from 4,500 years ago that is still in use today.
Copper pipe has strong, corrosion-resistant properties, and has become the first choice of modern contractors in the installation of water piping, heating and cooling piping in all residential commercial properties.
Advantages of copper pipe
1, copper is economical. Because copper pipe is easy to process and connect, so that when it is installed, it can save material and total cost, stability and reliability, can save maintenance.
2, copper is lightweight. For the same inner diameter of the internal threaded pipe, copper pipe does not need the thickness of ferrous metal. When installed, copper tubing has a smaller delivery cost, is easier to maintain, and takes up less space.
3. Copper can change shape. Because copper pipe can be bent and deformed, it can often be made into elbows and joints, and smooth bends allow copper pipe to be bent at any angle.
4,Copper is easy to connect.
5, copper is safe. It does not leak, does not promote combustion, does not produce toxic gases, and is corrosion resistant.
Purple copper pipe use
High strength at low temperature. Commonly used in the manufacture of heat exchange equipment (such as condensers, etc.). Also used in oxygen equipment assembly of low-temperature piping. Small diameter copper tube is often used to transport pressurized liquids (such as lubrication system, oil pressure system, etc.) and used as instrumentation pressure measurement tube.
Purple copper tubing is much more widely used than pure iron, and 50% of copper is electrolytically purified into pure copper each year for use in the electrical industry. Here said copper, indeed to be very pure, containing copper up to 99.95% or more before, a very small amount of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. Oxygen in copper (copper refining is easy to mix a small amount of oxygen) has a great impact on the conductivity, copper for the electrical industry generally must be oxygen-free copper. In addition, lead, antimony, bismuth and other impurities will make the copper crystallization can not be combined together, resulting in thermal embrittlement, will also affect the processing of pure copper. This pure copper of very high purity is generally refined by electrolysis: the impure copper (i.e., crude copper) is used as the anode, the pure copper is used as the cathode, and the copper sulfate solution is used as the electrolyte. When the current passes, the impure copper on the anode gradually melted, pure copper will gradually precipitate on the cathode. The copper refined in this way; the purity can reach 99.99%. Purple copper is a relatively pure kind of copper, generally can be approximated as pure copper, electrical conductivity, plasticity are better, but the strength, hardness is worse.
