Product Introduction
Copper pipe (also known as red copper pipe), often used in water pipes, heating and cooling pipes, can be used in different environments. Copper pipe set the advantages of metal and non-metal pipe in one, in the hot and cold water system exclusive, is the best connection pipe. Copper pipe is refractory to fire and heat, and can still maintain its shape and strength at high temperature without aging phenomenon.
The pressure capacity of copper pipe is several times or even dozens of times that of plastic pipe and aluminum pipe, and it can withstand the highest water pressure in today's buildings. In hot water environment, with the extension of service life, the pressure bearing capacity of plastic pipe decreases significantly, while the mechanical properties of copper pipe remain unchanged in all thermal temperature ranges, so its pressure bearing capacity will not decrease, nor will there be aging phenomenon.
The linear expansion coefficient of copper pipe is very small, which is 1/10 of that of plastic pipe. It will not cause stress fatigue rupture due to excessive thermal expansion and cold contraction.
The strength of copper pipe is greater, and the outer diameter is smaller under the requirement of ensuring the effective inner diameter, which is more suitable for dark burial.
Advantages of copper pipe
Copper pipe is hard, not easy to corrosion, and resistant to high temperature, high pressure, can be used in a variety of environments. Compared with this, the shortcomings of many other pipes are obvious, such as the galvanized steel pipe used in the past, which is easy to rust, and the tap water will be yellow and the water flow will become small after a short time of use. The strength of some materials will quickly decrease at high temperatures, which will be unsafe when used in hot water pipes. Copper has a melting point of 1083 degrees Celsius, and the temperature of hot water systems is insignificant to copper pipes. Archaeologists have discovered 4,500 years old copper pipes in Egyptian pyramids that are still in use today.
Copper pipes are durable
The chemical properties of copper are stable. It is resistant to cold, heat, pressure, corrosion and fire (the melting point of copper is as high as 1083 degrees Celsius) and can be used in different environments for a long time. The service life of copper pipe can be as long as the life of the building, or even longer. For example, the copper plumbing fittings installed in Peking Union Medical College Hospital in the 1920s have been in good performance for more than 70 years. It can be seen that copper pipe is fully tested by more than 100 years of time and practical experience.
Copper pipe is safe and reliable
Copper pipe combines the advantages of metal pipe and non-metal pipe. It is harder than plastic pipe and has the high strength of general metal (the strength of cold-drawn copper pipe is comparable to that of steel pipe with the same wall thickness); It is more flexible than the general metal, good toughness and high ductility, with excellent vibration resistance, impact resistance and frost heaving resistance.
Copper tube can withstand extremely cold and extremely hot temperature, from -196 degrees to 250 degrees, and adapt to drastic changes in temperature (- high temperature - low temperature - high temperature -), the use of performance will not be reduced by long-term use and drastic changes in temperature, will not produce aging phenomenon. This is the ordinary pipe can not be.
The linear expansion coefficient of copper pipe is very small, 1/10 of that of plastic pipe, and it can resist fatigue. When the temperature changes, it will not produce excessive thermal expansion and cold contraction, resulting in stress fatigue rupture.
These characteristics make the application of copper pipe in cold areas very advantageous. In the cold area, the temperature difference between morning and evening is large, and the linear expansion coefficient of ordinary pipes is large and the strength is low, so it is easy to produce stress fatigue rupture caused by thermal expansion and cold contraction. Some of the so-called -20 degrees is not brittle, but in fact can not bear the working pressure, and the service life is very short, does not have practical significance, although insulation measures can be used, but in the transportation, storage and installation process of low temperature is inevitable, and the performance of copper pipe at -183 degrees and room temperature is the same.
Copper pipe sanitation and health
Copper pipe has no plastic pipe of various modifiers, additives, additives and other chemical components.
Biological research shows that E. coli in water supply can no longer reproduce in copper pipes. More than 99% of the bacteria in the water were completely killed after five hours in the copper pipe.
The structure of copper tube is extremely dense and impermeable. Harmful substances such as oil, bacteria, viruses, oxygen and ultraviolet rays cannot pass through it and pollster the water quality.
In addition, copper pipe does not contain chemical additives, will not burn to release toxic gases to suffocate people. The recycling of copper is conducive to environmental protection and is a green building material for sustainable development.
Strong connection firmness of copper pipe
There are a variety of pipes on the market, but the interface fittings are in the majority of copper, even if some pipe parts can not use copper fittings, it should have a copper fittings in the place of the interface with the tap. However, if copper pipe fittings are connected with other pipes, due to the different materials of pipes and fittings, the physical and mechanical properties of thermal expansion and cold contraction are very different, and the firmness of the connection is naturally subject to additional challenges. Therefore, copper pipe and copper fittings connection, firmness will be greatly enhanced.
Good for health
Copper water pipe is good for health, copper water pipe water - saving antifouling and sterilization. When choosing or renovating a house, few people ask about the water supply. In fact, the material of water pipes can greatly affect people's health.
