The difference between seamless aluminum tubes and seamed aluminum tubes

The seamless aluminum tube has better pressure bearing than the seamed aluminum tube. The texture of the seamless tube is relatively uniform. The chemical composition of the welded tube will be burnt a little at the weld part, so the mechanical properties are slightly worse but not very different. If it is used for bending pipe, it is recommended to use a seamless aluminum pipe. The welded pipe is easy to crack. There is no problem if the bending radius is relatively large. The seamless aluminum tube is formed by perforation extrusion, while the conventional aluminum tube is generally extruded with a combined die. In the production, short rod, high temperature, the slow extrusion process is used, especially when the "three temperatures" must be well controlled.

The aluminum ingot processing method used for seamless aluminum alloy tubes and seamed aluminum alloy tubes is different. Seamless aluminum tubes use surface turning, and seam aluminum tubes use non-oxidized scale incorporation.

In terms of mechanical properties, seamless aluminum pipe products have uniform metal flow at the beginning and end, high dimensional accuracy, good fatigue resistance, consistent mechanical properties, and no lamellar structure. The metal flow at the beginning and the end of the seamed aluminum tube product cannot be uniform, the mechanical properties are inconsistent, and the layered structure is easy to appear. On the whole, it is better to choose a seamless aluminum tube, but you also need to determine the choice according to your own situation.

Two important characteristics of aluminum tube: bending and connection

Three Main Factors for Aluminum Elbow

1. Formability

Some aluminum alloys, such as 3000, 5000 and 6000 series, have higher formability than other aluminum alloys, making them good bending materials. Generally, alloys with higher formability have lower strength.

2. Thickness and Bending Radius

Like other metals, aluminum will appear "work hardening" during bending. This means that it will become stronger and stronger when formed. However, if ratio of radius to pipe thickness is too small, the material will be over machined and more likely to lose efficacy.

3. Rate of Elongation

Percentage of elongation is a way of describing the difference between the yield strength of a metal and its ultimate tensile strength. Yield strength is the point at which an aluminum alloy can be bent and no longer restored to its original shape. The greater the difference between these strengths, the better the formability of the alloy.

Connecting pipe usually means that one pipe is connected to another pipe or one end is connected to a container. Most commercially produced tubes can be equipped with connectors designed for specific types, shapes, and sizes of tubes.Quick Quote

Brazing and welding of aluminum pipe

Welding is to join metals by melting and fusing metals, with filler material be added. Fusion need to concentrate the heat directly at the joint, and the temperature must exceed the melting point of the metal and filler. Welded joints are usually as strong as the base material.

The difference between brazing and welding is that the temperature is much lower and does not melt the base metal. Instead, the heat source melts the filler metal and draws it into the joint through capillary action. It forms a metallurgical combination between the filler metal and the part surface.

As with welding, joint strength usually exceeds the strength of individual parts. For example, the tensile strength of stainless steel joints can exceed 130000 psi. However, due to the low brazing temperature, usually 1150 to 1600 ° F, most physical properties are not affected. Deformation and warping are minimized, which minimizes the stress in the joint area.

Four classification methods of aluminum tubes

By shape: square tube, round tube, embossed tube, profiled tube, globe aluminum tube.

By extrusion method: seamless aluminum tube and ordinary extruded tube.

By precision: ordinary aluminum tube and precision aluminum tube.Quick Quote

Precision aluminum tubes generally need to be re-processed after extrusion, such as cold drawing, fine drawing and rolling.

By thickness: ordinary aluminum tube and thin-walled aluminum tube.
