Embodiment 1

[0046] A method for producing an equivalent lightweight internally threaded copper pipe, comprising the steps of:

[0047] Step 1: Obtain molten copper through electrolysis; place the molten copper on a continuous casting machine for horizontal continuous casting, pour it onto a mold, and obtain a billet;

[0048] Step 2: placing the billet on an automatic rolling machine for processing to obtain a rolled tube;

[0049] Step 3: Carry out the combined drawing operation on the rolled tube, and then perform the coil drawing process on the combined drawn tube to obtain the parent tube, and then perform online annealing on the parent tube;

[0050] Step 4: After straightening the main pipe, perform internal thread forming;

[0051] Step 5: Transport the formed internally threaded copper pipe to the pre-inspection device through the conveying device, and the qualified product is sent to the pit furnace after finishing for annealing operation;

[0052] Wherein: the equipment and para...

Abstract

The invention belongs to the field of preparation of internally threaded copper pipes, in particular to TP2 internally threaded copper pipes for refrigeration and a preparation method thereof. The invention provides an equivalent lightweight production method for internally threaded copper pipes, through which the efficient production of internally threaded copper pipes can be realized and the qualified rate can be improved; meanwhile, the present invention also provides an internally threaded copper pipe, the internally threaded copper pipes Under the same energy efficiency and equivalent inner and outer diameters, the weight per meter of the tube can be reduced to a certain extent, and the cost of copper tubes can be reduced.

Description

technical field [0001] The invention belongs to the field of preparation of internally threaded copper pipes, in particular to TP2 internally threaded copper pipes for refrigeration and a preparation method thereof. Background technique [0002] Internally threaded copper tubes are widely used in daily production and life. Due to the increase in the inner surface area of ​​internally threaded copper tubes, its thermal conductivity is 20 to 30% higher than that of bare tubes. Therefore, internally threaded copper tubes are currently used Widely used in the air conditioning and refrigeration industry. [0003] For example, CN201910201066.X discloses a kind of internally threaded copper pipe and its processing technology, but the current traditional technology generally has the problem of high product defect rate, which seriously affects product quality. [0004] In addition, while the air-conditioning and refrigeration industries have higher requirements for heat transfer ene...
