subject: Brass?? Pipes In The Field Of Bright Pearl - Tileable Stone Texture - Seamless Stone Texture [print this page] Since December 1999 the relevant state ministries and commissions jointly issued the "backward elimination on the products in residential construction in the notice" after the new housing has been banned for indoor use galvanized steel pipe used to. This led to major changes in water supply pipe in the industry, a variety of new water supply pipe after another. Coincidentally, both sides, the eyes of investors locked in "New models, new technology" for some original, development and stability of the product but very few people is interested. In fact, of which there is no lack of military Miguel, copper is one of them. With the pipe industry, the continuous development of potable water copper pipe in residential applications is also starting to prove edge.
In our early days, copper water pipe as the water supply system has played an extremely important role, because copper was needed for countries classified as war material, can not be arbitrarily residential use, so copper industry in the domestic water system use by certain restrictions, the price trend has rapidly increased. Number of reasons why the brass has been relatively slow development, susceptible to the attention of investors. In fact, the area of water supply in the international copper pipe has long been praised in many developed countries and regions in the real estate building material of choice of copper as a water supply system. 85% of U.S. water supply system is made of copper, in Hong Kong and Singapore, the proportion of copper water supply systems, respectively 75% and 85%.
Copper is the main raw materials of non-ferrous metals of copper pipe, here is the thin copper. It is by drawing, extrusion or rolling forming seamless. Points according to whether the coating material, a bare copper pipe and plastic coated copper pipe (the exterior was covered with hot extruded plastic coating to protect copper pipe and pipe insulation). Thin-walled copper tube connections using brazing and hard soldering with copper-free silver, copper low silver hard solder (solder melting point higher than 620 ). Compared with the average water pipes, copper water pipes has its unique advantages:
Mechanical high, ductile
Copper pipe hard, high strength, tensile strength of not less than 205 ~ 305Mpa, the production by the small diameter drawn from, the work pressure pipe wall thickness is much greater than the requirements, because of its thinner wall pipe extended out, the use of fewer materials, less weight can greatly reduce the strength of the workers work.
Optimum temperature, good corrosion resistance
Copper pipes can adapt to temperature -196 to 205 , the temperature tolerance so strong, so copper water pipes in any climate or temperature conditions to any installation, performance will not be long-term use and temperature decrease. Copper is inert elements, in the chemical activity in the ordinal ranking is very low, only stronger than gold and silver, the black oxide surface is the most hard protective, corrosion resistance, do not pollute the water.
Strong antimicrobial activity and healthy environment
Bacterial growth inhibition of copper unique features, even more copper water pipes has become the only inhibitory function of water supply. Can inhibit bacterial growth, keeping drinking water clean. A biological survey showed that E. coli in water supplies are no longer continue to multiply in the copper tube, 99% of the bacteria into the water after 5 hours of brass will automatically disappear. While copper can be recycled, reused. According to the statistics show that: the annual domestic 1 / 3 of the copper can be reused. Therefore, copper pipe is a national green building materials recommended.
Smooth wall, flow resistance
Fluid flow properties within the brass tube a lot better than the other. Copper pipe wall due to smooth the flow resistance is small, easy to cause poor flow or obstruction, the copper water supply system can not only use the small size of thin brass, save timber, it can reduce a lot of energy.
An investment, long-term benefit
Water supply problem is in the area most likely to interface, while the brass as long as the installation properly, the pressure capacity of its interface better than the whole water supply system. And easy installation no maintenance, no pollution. In terms of price, if only from an investment point of view, the price of copper water supply systems are not advantages to the Shanghai General Ershiyiting house decoration, for example, if all the hot and cold water pipes used copper water pipes at a cost of around about 1,000 yuan. For consumers, these costs in the home decoration share of the expenditure is not significant. But you can see, the life of copper pipe is generally 3 to 4 times the pipe. While copper has a high strength metal, hard crack, break, and has anti-freezing and impact resistance, so construction of the plumbing system of copper water pipes were installed, they can achieve good results in safe and reliable, even No repairs and maintenance, so the overall cost is very economical.
With the continuous development of "safe, efficient, environmentally friendly" has become a vast number of consumers and investors the most talked about. The copper pipe water supply systems in residential use serves to meet the needs of the times. The relevant market surveillance, currently about 30% of consumers favor more copper water pipes, more and more investors are more optimistic about prospects for the development of this area.
