Copper industry knowledge: advantages and disadvantages of copper tubes
Advantages and disadvantages of copper tubes. Copper tubes are a type of non-ferrous metal tubes, which are pressed and drawn seamless tubes. Copper tubes have good thermal conductivity, and are strong and corrosion-resistant. They will not crack when the ambient temperature is relatively low, making them the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial houses.
Application of copper tubes
Copper tubes are generally used in heat exchange equipment, and can also be used in low-temperature pipes in oxygen production equipment. Some thinner copper tubes can be used to transport some pressurized liquids, and can also be used as pressure measuring tubes in instruments; in addition, copper tubes are relatively strong, unlike other metals that are easily corroded, so now many water pipes and refrigeration pipes used in buildings will choose to use copper tubes.
Advantages of copper tubes
1. Durable: The chemical properties of copper are stable, and it combines the characteristics of cold resistance, heat resistance, pressure resistance, corrosion resistance and fire resistance, and can be used for a long time in different environments.
2. Safe and reliable: Copper tubes combine the advantages of metal pipes and non-metallic pipes. It is harder than plastic pipes and has the high strength of general metals (the strength of cold-drawn copper pipes is equivalent to that of steel pipes with the same wall thickness); it is easier to bend than general metals, has good toughness and high ductility, and has excellent vibration resistance, impact resistance and frost heave resistance.
3. Hygiene and health: various chemical components such as modifiers, additives, and additives of plastic pipes in copper pipes.
4. The connection of copper pipes is strong: copper pipes are connected with copper accessories, and the connection is strong.
5. The price of copper pipes is economical. A lot of materials can always be saved in the process of installing copper pipes. Copper pipes are very easy to process and manufacture. Copper pipes are light in weight. Compared with other ferrous metal threaded pipes with the same inner diameter, copper pipes do not need to be as thick as ferrous metals. The transportation cost of installing copper pipes is lower, and it is very easy to maintain. Copper also has the characteristic of being able to change its shape at will, so copper pipes can be bent or deformed and are easy to connect. Since copper can be deformed at will, copper tubes are also made into copper pipe fittings. Copper is also corrosion-resistant and environmentally friendly. It is said that archaeologists have discovered copper water pipes with a history of thousands of years in the Egyptian pyramids, and the water flowing out of the copper water can still be used. Therefore, the advantages of copper tubes can be summarized as economic performance, easy connection, safety, and corrosion resistance.
6. Advantages of copper tubes:
(1) Advantages of oxygen-free copper tubes: Oxygen-free copper tubes have high purity, excellent electrical conductivity, thermal conductivity, cold and hot processing performance and good welding performance, and no "hydrogen disease" or very little "hydrogen disease".
(2) Advantages of pure copper tubes:
① Advantages of T2 copper tubes: Contains trace impurities and oxygen, has high electrical conductivity, thermal conductivity, good corrosion resistance and processing performance.
② Advantages of T3 copper tubes: Contains more oxygen and impurities, has good electrical conductivity, thermal conductivity, corrosion resistance and processing performance.
(3) Advantages of phosphorus deoxidized copper tubes: good process performance, good welding performance, good cold bending performance, generally no "hydrogen disease", can be used in a reducing atmosphere, but cannot be processed and used in an oxidizing atmosphere.
