Divided by extrusion method: seamless aluminum tube and ordinary extruded tube
Extruded aluminum pipe: billet heating → hot extrusion → sawing → turning, boring → wool heating → secondary extrusion → tension correction or roller correction → cutting chuck → intermediate inspection → annealing → corrosion → scraping repair → Cold rolling → annealing → heading → drawing → quenching → shaping diameter → finishing and straightening → sampling of finished products → artificial aging → finished product annealing → inspection and acceptance → oil coating
3003 seamless aluminum tube is perforated and extruded, while the conventional aluminum tube is generally extruded using a combination die. In the production process, short rod, high temperature, and slow extrusion processes are used. In particular, the "three temperatures" must be controlled. The aluminum rods, extrusion barrels, and dies must be kept clean. Adjust the size appropriately. Large 3003 seamless aluminum tubes are generally hot extruded and then subjected to subsequent effective treatment; small 3003 seamless aluminum tubes can be hot extruded or cold drawn, and then subjected to subsequent effective treatment.
3003 seamless aluminum pipe advantages:
The first is the welding technology advantage: suitable for industrial production of thin-walled copper-aluminum pipe welding technology, is the key technology for the replacement of copper in the air-conditioning pipe aluminum.
Second, the service life advantage: from the inner wall of the aluminum pipe, because the refrigerant does not contain moisture, the inner wall of the copper-aluminum connection pipe will not corrode.
The third is the energy-saving advantage: the lower the heat transfer efficiency of the air-conditioning indoor unit and the outdoor unit, the more energy-saving, or the better the insulation effect, the more power-saving.
The fourth is excellent in bending performance and easy to install.
