Seamed tubes and seamless tubes under which good?
A pipe is better than pressure welded aluminum tube, seamless aluminium pipe texture is relatively uniform, there will be a small amount of loss in the part of the chemical composition of weld, so the mechanical properties of poor and seamless, but not big difference.Two, if the elbow pipe would recommend the use of seamless pipe, easy to crack, the bending radius is large enough no problem, that is because although there is high frequency welded pipe welding seam, but it is a composite aluminum tube, which is composed of Aluminum Alloy material more than 2, its surface layer for brazing layer.Three, aluminum tube refers to the use of pure aluminum or aluminum alloy extrusion processing into its longitudinal length of hollow metal tubular material. There may be one or more closed through holes with uniform wall thickness and cross section to be delivered in a straight or coiled form. Widely used in automobiles, ships, aerospace, aviation, electrical appliances, agriculture, machinery and electrical, home and other industries.1, according to the shape of: square tube, round tube, pattern tube, special-shaped tube;2, according to extrusion method: seamless aluminum tube and ordinary extrusion pipe;3, according to precision points: ordinary aluminum tube and precision aluminum tube, in which the precision aluminum tube generally needs to be processed after extrusion, such as cold drawn, fine drawn, rolling;4, according to thickness points: ordinary aluminum tube and thin-walled aluminum tube.Four: Performance: corrosion resistance, light weight.Five, aluminum tubes are widely used in all walks of life, such as: automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electrical and mechanical, home, etc., aluminum pipe in daily life has been everywhere.
Seamless aluminium bearing is better than welded aluminum tube, seamless texture is relatively uniform, there will be a small amount of loss in the pipe part of the chemical composition of weld, so the mechanical properties poor and seamless pipe! But not very different! Seamless pipe is recommended if it is used for elbow! The welded pipe is easy to crack! Bending radius is relatively large, then no problem!
The aluminum tubes are extruded and are seamless. We have not seen welded aluminum tubes, except for large caliber ones. The biggest extrusion machine in China can do the aluminium tube about 600 of the outer diameter
