seamless aluminium tube manufacturing process is generally the use of perforation extrusion method, due to the seamless aluminum tube has a small proportion, easy to process, mechanical strength and other characteristics, in fact, seamless aluminum tube production process requirements are relatively strict, relatively fine.


But in the production should pay attention to some problems, in order to produce a qualified seamless aluminum tube.The following is to share with you seamless aluminium tube manufacturing process needs to pay attention to the problem and some successful practical experience.
Large seamless aluminium tube manufacturing process generally are hot extrusion forming, and then after the subsequent effectiveness of treatment.And the small seamless aluminum tube, can be hot extrusion or cold stretch, and then after the actual effect of treatment.
The alumina hydrate produced in seamless aluminium tube manufacturing process needs to be continuously extruded.In order to prevent the sand hole on the seamless aluminum tube, the round aluminum rod used for extrusion should not have rolling crack.Do not store in the humid environment, the cleaning solution in the sodium hydroxide content of about 30 percent is appropriate, to strictly control the cleaning solution in the content of aluminum ions.
