Brass Pneumatic Fitting with Ce/RoHS (EM-F-A025)

Main advantages of copper tubes
1, copper tube durable
Copper chemical stability, will be cold, heat, pressure, corrosion resistance and refractory (copper melting point up to 1083 degrees Celsius) and other characteristics set in a body, 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, such as the Peking Union Medical College Hospital in the last century, in 20s, the installation of copper plumbing pieces after more than 70 years, still has a good performance. It can be seen that the copper tube is more than one hundred years of time and practical experience to fully test the pipe.
2, copper safety and reliability
The advantages of the copper pipe and the non metal pipe are all in one body. It is hard plastic pipe, high strength with metal (steel cold drawn tubes with same intensity of wall thickness; equivalent) it is generally flexible metal, and good toughness, with anti vibration, impact resistance and frost resistance performance.
Brass can withstand extreme heat and extreme cold temperatures from 196 degrees to 250 degrees wide application range, and adapt to the drastic changes in temperature (high temperature low temperature and high - Performance), the use will not decrease due to dramatic changes in temperature and long-term use, will not produce the aging phenomenon. This is ordinary pipe can not and.
The linear expansion coefficient of the copper tube is very small, it is the 1/10 of the plastic pipe. When the temperature changes, not excessive heat bilges cold shrink and cause stress fatigue fracture.
These characteristics make the application of copper tube in cold regions have great advantage. Cold area temperature sooner or later, the linear expansion coefficient of ordinary pipe and high strength low, easy to produce and produce due to thermal expansion stress fatigue rupture. Some so-called -20 degrees, but can not bear the pressure of work, and the service life is short, do not have the practical significance, although can use insulation measures, but in the transportation, storage and installation process encounter cold is difficult to avoid, and brass performance is the same in -183 and at ambient temperature.
3, copper health
Plastics containing "plasticizer" and other chemical components, will be the time and temperature changes, resulting in plastic hardening and embrittlement. Copper pipe is not a variety of plastic pipe modifiers, additives, additives and other chemical components.
Biological studies have indicated that the bacteria in the water supply can not continue to propagate in the copper tube; more than 99% of the bacteria in the water after entering the copper tube 5 hours after being completely killed.
Copper tube structure is extremely dense, with non permeability. Whether it is fat, bacteria, viruses, oxygen and ultraviolet radiation and other harmful substances can not pass through it and the pollution of water.
In addition, the copper tube does not contain chemical adding ingredients, will not burn the release of toxic gases make people suffocation. Recycling of copper is conducive to environmental protection, is the sustainable development of green building materials.
