C12200 Copper Pipes China Factory
C12200 copper pipes, also known as DHP (Deoxidized High Phosphorus) copper pipes, are a type of copper pipe that is widely used in various industries and applications. These pipes are known for their excellent thermal and electrical conductivity, corrosion resistance, and high ductility. In this comprehensive answer, we will delve into the properties, uses, manufacturing process, advantages, and applications of C12200 copper pipes.
Properties:
C12200 copper pipes are made from pure copper with a minimum copper content of 99.9%. They have a reddish-orange color and exhibit excellent thermal and electrical conductivity. The thermal conductivity of C12200 copper pipes is approximately 391 W/m·K (Watts per meter Kelvin), making them highly efficient in transferring heat. In terms of electrical conductivity, these pipes have a conductivity rating of around 101% IACS (International Annealed Copper Standard), which means they conduct electricity better than pure copper.
C12200 copper pipes also possess good corrosion resistance, especially in environments where they are not exposed to harsh chemicals or acidic conditions. They have high ductility, allowing them to be easily bent or formed without cracking or breaking. Additionally, these pipes have low magnetic permeability, making them suitable for applications where magnetic interference needs to be minimized.

Manufacturing Process:
The manufacturing process of C12200 copper pipes involves several steps. It typically starts with the extraction of copper ore from mines. The ore is then crushed and ground into a fine powder before undergoing a series of chemical processes to remove impurities and refine the copper content.
Once the copper is purified, it is melted in a furnace and cast into billets or ingots. These billets are then heated and extruded through a die to form long cylindrical tubes with the desired dimensions. The extruded tubes are then annealed to relieve internal stresses and improve their mechanical properties.
After annealing, the tubes are subjected to various finishing processes such as straightening, cutting, and polishing to achieve the final product, which is the C12200 copper pipe. The pipes may also undergo additional treatments like cleaning and coating to enhance their surface finish and protect them from oxidation.
