1, extruded seamless aluminum tube pipe than the pressure of the joint aluminum pipe is better, seamless aluminum pipe texture is more uniform, welded pipe in the weld part of the chemical composition will have a small amount of burning loss, so the mechanical performance is slightly poor and seamless pipe, but not very different.
2, if it is a bend pipe, it is recommended to use seamless pipe, welded pipe is easy to crack, if relatively large, it is also no problem, that is because although the high-frequency welded pipe has welded joint, but it is a composite aluminum tube, it is composed of more than two aluminum alloy materials, generally its surface layer for brazing layer.
3. Aluminum tube refers to a tubular metal material with hollow length along its longitudinal length processed by extrusion with pure aluminum or aluminum alloy.There may be one or more closed through-holes of uniform wall thickness and cross section, delivered in straight or rolled form.Widely used in automobile, ship, aerospace, aviation, electrical appliances, agriculture, mechanical and electrical, home and other industries.
1, according to the shape: square pipe, round pipe, decorative pattern pipe, shaped pipe;
2, according to the extrusion mode: seamless aluminum tube and ordinary extrusion tube;
3. According to precision: ordinary aluminum tube and precision aluminum tube, in which precision aluminum tube generally needs to be reprocessed after extrusion, such as cold drawing, fine pumping and rolling;
4. According to thickness: ordinary aluminum tube and thin-walled aluminum tube.
Performance: corrosion resistance and light weight.
5.,Extruded seamless aluminum tube pipe is widely used in all walks of life, such as: automobile, ship, aerospace, aviation, electrical appliances, agriculture, mechanical and electrical, home, etc., aluminum tube in daily life has been everywhere.
