ASTM C22000 Common Brass Seamless Tubes Good Material For Hot Water Supply Pipeline
1. Description
ASTM C22000 brass tube is hard, not easy to corrosion, high temperature and high pressure resistance. It can be used in many environments. Compared with this, the disadvantages of many other pipelines are obvious. For example, galvanized steel pipes used in residential buildings in the past were easy to rust. If it is used for a short time, the tap water will turn yellow, the water quality will become rusty, and the water flow will become smaller. The melting point of ASTM C22000 brass is as high as 1083 ℃. For this kind of copper tube, the temperature of hot water can be ignored. Archaeologists have found a copper pipe 4500 years ago in the Egyptian pyramids, which are still usable today. It can be seen that the use of brass tube is very long.
