Issues related to coaxiality in the processing of screw conveyors
Thread Content
Recently, my workplace needs to manufacture a screw conveyor whose cylinder is welded to the flanges on both sides. I would like to ask those with experience in this field: what welding process and sequence can ensure that the cylinder and the flanges on both sides are coaxial, and that the axis of the tube is perpendicular to the end faces of the flanges?
First, the equipment should be installed and aligned properly. During the piping process, it is advisable to start piping from the far end towards the equipment. Before welding the flanges at both ends of the equipment, measurements should be taken at the equipment’s base to monitor any displacement caused by pipeline stress. When welding, it is best for two welders to work simultaneously in order to minimize pipeline stress, and changes in the measurement values should be monitored throughout the welding process.
Do you mean to secure both sides first, then align the cylinder before welding?
