Advantages of Thick-walled Brass Tubes

Thick-walled brass tubes are light in weight, good in thermal conductivity and high in cryogenic strength. They are often used to manufacture heat exchangers (such as condensers) and to assemble cryogenic pipes in oxygen plants. Copper pipes with small diameters are often used for transporting pressurized liquids (such as lubrication systems, oil pressure systems, etc.) [...]
