The advantages of air-conditioning copper tube production process and copper tube floor heating

[1] Production technology of air-conditioning copper pipe

1. Up-quoting method: This production method is electrolytic copper after direct melting of copper pipes.

Advantages: low investment cost, low production cost, high output and cheap price.

Disadvantages: The pipe structure is loose and not resistant to high pressure, so it is only suitable for the production of small air-conditioning copper pipes.

2. Continuous casting and rolling method: This production method is to cast hollow copper billets directly after electrolytic copper smelting, and to produce copper tubes by planetary rolling method.

Advantages: low production cost and high production efficiency.

Disadvantages: Due to loose tissue and high pressure resistance, the pipeline is limited to the production of small air-conditioning copper rods.

3. Extrusion method: This production method is to cast copper ingots after smelting, and extrude copper tubes from large extruders after secondary heating.

Advantages: good quality, fine structure, high density, high pressure resistance, large bending deformation, suitable for frequent cold and heat exchange, large temperature difference in working environment, and large size copper tubes can be produced.

Disadvantages: low output, high production cost and high price. The extruded copper tube method is a stable and excellent copper tube production method at home and abroad. Only the copper tube produced by this process is more suitable for the HVAC field, and it is the development direction of the copper tube industry in the future.

[2]. Advantages and scope of application of copper tube floor heating

Today, floor heating is not only a comfortable way of heating, but also a sign of modern quality of life. More and more houses, public buildings, sports facilities, industrial facilities and other places start to use floor heating.

Radiators are an important part of floor heating. Due to the corrosion resistance of copper, copper tubes are selected as the main material of radiators in many places. Let us explain the advantages of copper pipe material:

Copper tube floor heating refers to the heating method that uses hot water as the heat medium, circulates in the copper tube heating tube, heats the floor, and heats the floor through the ground in the form of radiation and convective heat exchange. one. The copper pipe has fast heat dissipation effect and strong heat resistance. Even in the case of high temperature water supply, it still does not affect the life of the floor heating pipe. two. Copper tubes are metal tubes, so they are not easy to scratch. Therefore, it is not easy to leak. three. High temperature resistance, high pressure resistance, compared with any ordinary plastic pipe. The copper pipe floor keeps warm and is resistant to high temperature and high pressure. four. long lasting. five. The material of the water separator is the same, the expansion coefficient is the same, and the connection with the water separator is not easy to leak. Scope of application: Since copper pipes are more expensive, more than twice as expensive as plastic pipes, the cost of the floor heating system is relatively high.
