Brass pipe commonly used grades H59, H59-1, H62, H63, H65, H68, H70. brass pipe with strong, corrosion-resistant properties, and become the modern contractor in all residential commercial housing water piping, heating, cooling piping installation of choice. Brass pipe is the best water supply pipe. Brass pipe characteristics: light weight, good thermal conductivity, high strength at low temperatures. Commonly used in the manufacture of heat exchange equipment (such as condensers, etc.). It is also used for assembling low-temperature piping in oxygen equipment. Small diameter copper pipe is often used to transport pressurized liquids (such as lubrication system, oil pressure system, etc.) and used as instrumentation pressure measurement pipe.
Brass pipe has a strong, corrosion-resistant properties, and become a modern contractor in all residential commercial housing water piping, heating, cooling piping installation of choice. Copper pipe melts many advantages in one: it is strong, with the high strength of general metal; at the same time than the general metal is easy to bend, easy to twist, not easy to crack, not easy to break, and has a certain degree of resistance to freezing and expansion and impact resistance, so the building of the water supply system in the copper water pipe is installed, the use of the safe and reliable, and even without the need for maintenance and repair.
Advantages of brass pipe: copper pipe is hard, not easy to corrode, and high temperature and high pressure resistance, can be used in a variety of environments. Compared with this, many other pipe shortcomings are obvious, such as the past residential galvanized steel pipe, very easy to corrosion, the use of time will not appear yellow tap water, water flow becomes small and other issues. There are also some materials at high temperatures will rapidly reduce the strength of the hot water pipe will produce unsafe hidden danger, and the melting point of copper up to 1083 degrees Celsius, the temperature of the hot water system on the copper pipe is insignificant.
