Brass is an alloy composed of copper and zinc. Only brass composed of copper and zinc is called general brass. Brass is often used to make gate valves, water pipes, rubber pipes in air conditioners, and radiators.
Brass tubes are generally used to make heating coils for coolers and cooling towers and general-purpose pipes. Brass tubes are used for No. 68 and No. 70 brass for coolers, and No. 62 brass for general-purpose cold-drawn pipes with diameters from 3 to 100 cm. Its length is 1-6 meters.
Condensation-cooling towers and other thermal equipment pipes need to be subjected to a hydraulic test with a pressure of 50KG/cm2, and the test time is not less than 10 seconds.
Compared with shell-and-tube heat exchangers, this type of heat exchanger recently used has the following advantages:
1. High thermal conductivity, which is due to high flow velocity, seepage and its complete backflow;
2. The equipment required for heat transfer in enterprises is relatively small;
3. Excellent temperature deformation compensation.
What are the characteristics and uses of brass tubes
Brass tubes combine many advantages. They have the high strength of ordinary metals. At the same time, they are easier to bump, change, crack, and break than ordinary metals. They also have certain frost heave and impact resistance. Therefore, the water supply system in buildings Once the copper water pipes inside are installed, they are safe and reliable to use, and do not even require maintenance.
The brass tube also has the characteristics of strong material, not easy to be corroded, heat-resistant and high-pressure resistant, and can be used in various environments. Compared with it, the defects of many other pipes are obvious. For example, the galvanized pipes commonly used in residences in the past are easy to rust, and the running water will turn yellow and the water flow will shrink after a short time of use. There are also some materials whose strength will decrease rapidly at high temperature, and there will be unsafe risks when used in heating pipes, while the melting point of copper is as high as 1083 degrees Celsius, and the temperature of the boiling water system is negligible for copper pipes. Nowadays, it is generally used as copper tubes for electrical appliances, copper tubes for refrigeration, high-voltage copper tubes, corrosion-resistant copper tubes, copper tubes for connections, copper tubes for waterways, electric heating copper tubes, and industrial-grade copper tubes.
In addition, due to its firmness and corrosion resistance, brass pipes have become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial buildings. At the same time, it also has the characteristics of light weight, good heat transfer, and high low-temperature strength. It is often used to make thermal equipment (such as coolers), etc., and is also used to install low-temperature pipelines in oxygen-generating equipment. Copper tubes with small diameters are often used to transport pressurized liquids (such as lubrication systems, oil pressure systems, etc.) and pressure measuring tubes for instruments, etc.
