The difference between thin-walled spiral steel tubes and thick-walled spiral steel tube

The difference between thin-walled spiral steel tubes and thick-walled spiral steel tube

Keywords :The difference between thin-walled spiral steel tubes and thick-walled spiral steel tube        Update : 2022-11-02        View(s) : 602

The concept of thin-walled spiral steel tube : the strip steel is fed into the welded pipe unit, rolled by multiple rollers, and the strip is gradually rolled up to form a circular tube blank with an opening gap, and the reduced amount of the extrusion roller is adjusted to make the welding seam ...
