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.
