Brass tube has light weight, good thermal conductivity and high low temperature strength. It is often used to manufacture heat transfer equipment (such as condenser, etc.). It is also used for assembling low-temperature pipelines in oxygen production equipment. Small diameter copper pipe is often used for conveying pressure liquid (such as lubrication system, oil pressure system, etc.) and used as instrument pressure tube, etc. Brass tubes are strong and resistant to corrosion.
Mainly has the following advantages: copper tube hard texture, not easy to corrosion, and high temperature resistance, high pressure resistance, can be used in a variety of not copper type environment. And compare with brass tube, the shortcoming of a lot of other pipe material is apparent, for instance in the past residence uses more galvanized steel tube, its rust is extremely easy, use time is not long can appear tap water hair yellow, current decrescent wait for a problem. There are also some materials in high temperature strength will quickly reduce, when used for hot water pipes will produce unsafe hidden dangers. But because copper has a melting point of 1,083 degrees, the temperature of the hot water system has little effect on brass tubes. Common brass tubes include electrical brass tube, refrigeration brass tube, high pressure brass tube, corrosion resistant brass tube, connection brass tube, waterway brass tube, electric heating brass tube and industrial brass tube.
(1) The brass tube has good thermal conductivity.
For copper, basically it conducts heat very well. Now a lot of heating equipment, will use this pipe to conduct heat, and in the heat if the use of brass tube can ensure that the heat conduction is fast, and will not emit, when conducting the process will not appear problems.
(2) Brass tubes are very light in weight.
For its light weight, many people will use the water pipe side. Both the home and the outdoors need water, and for the water itself, it can not flow out all of a sudden, but needs to be transported by pipes, from the source to the final release is flowing into the pipe, so this pipe will use brass pipe.
(3) low temperature of brass tube.
For brass tube itself, the temperature is very low, which means that this product can ensure the use of low temperature, use, and for some pressure systems, can be used in different places. Because copper is easy to rust, so for brass tube itself, its low temperature is relatively low temperature, so that the operation and later maintenance will reduce a lot of the above.
