Products Description
We are committed to improving product performance, launching new solutions almost every year for products such as copper tubing for oilfield pumping units, brass tubing for precision instruments, and copper refrigeration coils. If you have any needs, please allow us to collaborate and achieve mutual success. With scientific management and ample human resources, we have laid a solid foundation for the company's future development and leap forward. With the development of information technology and the advancement of economic globalization, we should be market-oriented, increase our technological innovation efforts, implement our brand strategy, and uphold integrity as our foundation.
C44300 naval brass tubing (composed of copper, zinc, and tin) used in evaporative coolers is a device that uses water evaporation to cool air. Evaporative cooling differs from traditional air conditioning systems that use vapor compression or absorption refrigeration cycles. Evaporative cooling utilizes the characteristic that water absorbs a large amount of heat when it evaporates (i.e., water has a high enthalpy of vaporization).
Alloy and production standard:
C44300 (ASTM B111 or ASME SB111)
CuZn28Sn1As (EN12451 or EN12449)
CuZn28Sn1 (DIN)
CZ111 (BS British Standard)
C4430 (JIS Japanese Industrial Standards)
Chemical composition:
70.0≤Cu≤73.0 ; 0.8≤Sn≤1.2;
Zn Rem; 0.02≤As≤0.06
Dimension/size:
Outside diameter range : 5mm~110mm
Wall thickness range : 0.3mm~10mm
Maximum length: 24 meters
Field of application:
Admiralty brass tube for cooler is generally intended for evaporative cooler, including but not limited to swamp cooler, swamp box, desert cooler and wet air cooler and so on. Evaporative coolers lower the temperature of air using the principle of evaporative cooling, unlike typical air conditioning systems which use vapor-compression refrigeration or absorption refrigerator.
Production features:
Our products have excellent conductivity, heat transfer properties, outstanding corrosion resistance, high pressure resistance, high temperature resistance, frost resistance, good mechanical properties, pressure processing and welding performance.
