1、 Seamless aluminum pipe
has better pressure bearing than seamless aluminum pipe
. The texture of seamless aluminum pipe is relatively uniform. There will be a small amount of chemical composition loss when welding the pipe, so the mechanical properties are slightly poor, but not with a huge difference.
2、 If it is used for bending, it is recommended to use seamless pipe. The welded pipe is easy to crack, and there is no problem if the bending radius is relatively large. That is because although the high-frequency welded pipe has welding joints, it is a composite aluminum pipe, which is composed of more than two aluminum alloy materials. The surface layer is normally a brazing layer.
3、 Aluminum tube refers to the metal tubular material that is extruded from pure aluminum or aluminum alloy to be hollow along its longitudinal full length. There can be one or more closed through holes with uniform wall thickness and cross section, which can be delivered in straight line or roll shape. Widely used in automobile, ship, aerospace, aviation, electrical appliances, agriculture, electromechanical, home and other industries.
1. According to the shape: square tube, round tube, pattern tube and special-shaped tube;
2. According to extrusion methods: seamless aluminum pipe and ordinary extruded pipe;
3. According to the precision, it is divided into ordinary aluminum pipe and precision aluminum pipe. The precision aluminum pipe generally needs to be reprocessed after extrusion, such as cold drawing, fine drawing and rolling;
4. By thickness: ordinary aluminum pipe and thin-wall aluminum pipe.
4、 Performance: corrosion resistance, light weight.
5、 Aluminum tubes
are widely used in daily life, such as automobile, ship, aerospace, aviation, electrical appliances, agriculture, electromechanical, home, etc.
