air conditioning is one of the essential electrical products in every family. It is used more frequently in hot summer. There are many internal materials of air conditioners, among which the air conditioning copper pipe is an important part of air conditioners. Many people don't know much about the price of air conditioning copper pipe, so the following editor will introduce the price of air conditioning copper pipe and the welding skills and precautions of air conditioning copper pipe. Let's have a look

I. price of air conditioning copper pipe

air conditioning copper pipe is divided into liquid pipe and air pipe. Its process is divided into extrusion process and stretching process. There is no specific standard for the price of air conditioning copper pipe. The price of different manufacturers and processes will vary. Generally, the price of air conditioning copper pipe is 100 yuan/M-300 yuan/m. The price of air conditioning copper pipe will be affected by many factors. You can consult local dealers when purchasing

II. Welding skills of air conditioning copper pipes

1. Clean or flare the surface of the pipe fittings to be welded. The flared part should be smooth, burr free, and uniform thickness, and then polish the welded copper pipes with sandpaper, otherwise it will affect the solder flow and welding quality

2. Insert the welded copper tubes into each other. Pay attention to the size and align the center of the circle when inserting

3. The weldment shall be preheated first, and the welding place of the copper pipe shall be heated. When it is heated to purple, it shall be welded with silver electrode. Place the solder against the crater to make it flow into the welded copper parts

4. In order to shorten the welding time, fast welding with strong flame is used to prevent too much oxide generated in the pipeline, which will block the Yin gas and dirty, and damage the compressor

III. precautions for air conditioning copper pipe welding

1. When welding, wait until the solder solidifies before moving the copper pipe, otherwise the welded part will crack

2. Welding can only be carried out after the refrigerant of R12 refrigeration system is discharged, otherwise R12 refrigerant will produce toxic phosgene when encountering open fire, which is harmful to human body

3. In order to ensure the firmness of the whole circuit, oxygen welding shall be adopted for the unit and condenser

4. Both gas pipes and liquid pipes must be covered with insulation pipes, and in order to be beautiful, they should be arranged on the same plane, and one part of the pipes should not be overlapped on another part of the pipes

5. The gas pipe should be tilted towards the condenser, so that the oil and refrigerant cannot flow back into the machine after shutdown

6. If straight copper pipes need annealing treatment before bending, stamping elbow welding should be adopted. When cutting copper pipes, use a special copper pipe cutter instead of a hacksaw blade

editor's summary: the above is about the price of air-conditioning copper pipe and the welding skills and welding precautions of air-conditioning copper pipe. Through the above content, you also know about the price and welding skills of air-conditioning copper pipe, and hope to help you
