Copper pipes are resistant to high temperatures and can be used in a variety of environments. Compared with this, the shortcomings of many other pipes are obvious. For example, the galvanized steel pipes used in residential buildings in the past are very easy to rust. If they are not used for a long time, there will be problems such as yellowing of tap water and small water flow. There are also some materials whose strength will decrease rapidly at high temperatures, which may cause unsafe hazards when used in hot water pipes. The melting point of copper is as high as 1083 degrees Celsius, and the temperature of the hot water system is negligible for copper pipes. Archaeologists discovered a copper water pipe 4,500 years ago in the Egyptian pyramids, which is still in use today.
1) Using advanced continuous casting and rolling production technology, high purity, fine structure, low oxygen content.
2) No pores, trachoma, porosity, with good thermal conductivity, processability, ductility, corrosion resistance and weather resistance.
3) Easy to weld and braze.
4) The product has stable quality, high pressure resistance, high elongation, and high cleanliness, meeting the high cleanliness needs of fluorine-free refrigeration equipment.
