The strong and corrosion resistant properties of brass make it the preferred choice of modern contractors for the installation of water mains, heating and cooling pipes in all residential commercial houses. Brass pipes are the best water supply.
Brass pipes are strong and corrosion-resistant, making them the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial houses. Copper pipe has many advantages: it is strong, with the high strength of ordinary metals; At the same time than general metal easy to bend, easy to twist, not easy crack, not easy to break, and have certain anti-freeze bilge and fight impact ability, because this is the construction of the water supply system in the copper conduit once installed, use safe and reliable, even without maintenance and maintenance.
Advantages of brass tube: copper tube hard texture, not easy to corrosion, and high temperature resistance, high pressure resistance, can be used in a variety of environments. Compare with this, the shortcoming of a lot of other pipe material is apparent, for instance the multi-purpose galvanized steel pipe in past residence, rust easily, use time is not long can appear tap water hair yellow, current decrescent wait for a problem. Still the intensity that some material falls in high temperature can be reduced rapidly, when be used at hot water tube can produce unsafe hidden trouble, and the melting point of copper is as high as 1083 degrees Celsius, the temperature of hot water system is negligible to copper tube.
