What are the advantages and disadvantages of copper pipes?

The advantages and disadvantages of copper pipes are listed below:

Advantages:

1. Strong durability:

Copper is chemically stable, has good corrosion resistance, and can resist the erosion of various chemicals. Corrosion resistance in the soil is better than other metal pipes, such as steel, iron and so on. Even in the humid, acid and alkali and other harsh environments, it is not easy to rust, corrosion, long service life, the longest can reach more than 70 years or even as long as the life of the building.

It has excellent resistance to freezing and expansion and impact, not easy to rupture and deformation, and can remain intact under natural disasters such as earthquakes.

2. Hygiene and health:

Copper has good antimicrobial properties and can effectively inhibit the growth of bacteria. Research shows that the water supply in the E. coli bacteria in the copper pipe can not continue to reproduce, more than 99% of the bacteria in the water into the copper pipe 5 hours after being completely killed, can prevent the growth of bacteria inside the water quality, to keep the water clean.

Copper pipe organization is extremely dense, with impermeability, whether it is grease, bacteria, viruses, oxygen and ultraviolet light and other harmful substances can not pass through it and contaminate the water.

Copper is one of the metal elements that human health can not lack, copper pipe in the separation of trace copper ions can supplement the body's demand for copper.

3. High temperature and pressure resistance:

The melting point of copper is up to 1083.4 ℃, can be used for a long time in a high temperature environment, will not be deformed or rupture, can withstand high water pressure, can be used in high-rise buildings and large-scale engineering projects.

4. Firm connections: copper water pipe connections are diverse and firm, such as welding and other connections to ensure that the water pipe connection parts of the sealing and stability, not easy to leakage and other issues.

5. Recyclability: copper is a recyclable material, in line with environmental requirements, and is conducive to the sustainable use of resources.

6. Easy to process: copper material is relatively soft, easy to bend, deformation, processing into a variety of shapes and sizes of water pipes and fittings, to meet the needs of different installation scenarios.

Disadvantages:

1. Higher price: copper is an important metal resource, the cost of raw materials is high, so the price of copper water pipe is relatively expensive, is currently more upscale water pipe, which to some extent limits its application in some cost-sensitive projects.

2. Easily oxidized: the surface of copper is easily oxidized, resulting in copper green or patina. Although the copper green itself is not harmful, it may affect the appearance of the water pipe, and to some extent, it will reduce the thermal conductivity of the water pipe.

3. Good thermal conductivity leads to poor insulation: the thermal conductivity of copper is high, hot water in the flow of copper water pipe heat is easy to lose, so in the hot water supply system needs to take additional insulation measures, such as wrapping insulation materials, etc., increasing the cost and complexity of the installation and use of the cost and complexity.

4. Installation complexity: compared with plastic water pipes, etc., the installation process of copper water pipes is relatively complex, the technical requirements of the construction personnel are higher. For example, welding installation requires specialized technology and equipment, and the quality of welding directly affects the service life and safety of water pipes.
