Air conditioning copper tube production process
1, on the lead method: this production method for the electrolytic copper after melting directly on the lead out of the copper tube.
Advantages: low investment costs, low production costs, high yield, cheap.
Disadvantages: loose pipe organization, not high-pressure, only suitable for the production of small-size air-conditioning copper pipe.
2, continuous casting and rolling method: this production method for the melting of electrolytic copper directly after casting a hollow copper billet, after the planetary rolling production of copper pipe.
Advantages: low production costs, high production efficiency.
Disadvantages: pipe due to loose organization, not high-pressure, limited to small-size air-conditioning production of copper pipe.
3, extrusion method: this production method for the melting and casting of copper ingots, after the second heating with a large extruder extrusion of copper tubes.
Advantages: the best quality, fine tissue structure, density, high pressure resistance, bending deformation, can be applied to the frequent exchange of heat and cold, temperature changes in the working environment, can produce large-size copper pipe.
Disadvantages: low yield, high production cost and high price. Extruded copper pipe production method is currently the most stable product quality at home and abroad in the production of copper pipe production method, the optimal copper pipe production method, only the process of copper pipe production is the most suitable for application in the field of HVAC, is the direction of the future development of the copper pipe industry.
Analysis of the situation of cracking often occurs when bending pipe
Copper pipe because of its relatively light weight, it is easy to conduct heat, and in the low temperature environment can also be used normally. Therefore, the application of purple copper pipe is very wide. It is not to say that there is no shortcomings of the copper pipe, such as the copper pipe bending often cracking, now we will find the reasons for the cracking of the copper pipe bending.
In the bending of copper pipe, it and stainless steel and pipe and iron pipe are more difficult to compare. Lead to cracking when the copper pipe bending, first of all and the quality of the copper pipe material has a relationship, in addition there is the degree of its bending, radius size, in addition to this is also related to is not wearing a mandrel.
If the quality of copper pipe is not up to standard, even if the degree of bending is within a reasonable range, the copper pipe will crack, or the pipe bend is flat, there are wrinkles and so on; if the copper pipe is too big to bend, the radius is too small, even if the quality of the copper pipe is very good, it will also be cracked or there are wrinkles, if you want to bend the radius of the copper pipe is relatively small, you have to wear mandrels.
