How to fix Aluminum tubes surface defects?

Answer:

First. Be careful not to cut too much as long as the removal of necking and space segments and pulling the tail section can crack when cutting should be careful not bevelled after the aluminum pipe should put away during cutting.
Fifth, when aluminum thermal expansion to the former three tubing wall thickness measuring it, even when the expansion is completed it made a single measurement, adjust the speed and temperature of the expansion of the system according to changes in these two measurements . For aluminum tube full circle repair industry is the most common repair contents, in which the pits or crushed there is a method to repair
Fourth, after the tube expansion is finished, a check of its outer tubes of the tube, to see whether the pipe surface defects, if defective, so that he can be eliminated on the timely elimination of the defects, if too much, can not to access the recovery furnace re-grinding clean.
Third, when the pipe may be used, as well as the thickness of the measurement record to do it the length of the tube, usually when used according to its specifications as well as the length of the wall thickness specifications choose to use, if there are stiff head tube to mark the timely, coming stiff head when using the site to slow down its use, and to increase the temperature.
Second, the aluminum material when placed on the shelf should be noted, first check that there is no damage to the surface, and then have to check there are no creases to cut it, there is no cutting Pakistan and India, etc. If Pakistan and India or a small number of shallow depth make it smoother after being placed in the rack, if it is found deep creases or Pakistan and India, which can not be added to the tube, it can not be used as a pipe, aluminum pipe after grinding use welding patch formation.
