The spiral steel pipe uses a steel roll plate as the raw material. It often squeeze the city and press the spiral shape. The raw materials are steel rolls, welded wires, and solder.
When the spiral steel pipe is produced, the wrong edges occur, and the influencing factors are many. In production practice, the steel pipe is often reduced by the dry and wrong side. Therefore necessary.
1. The sickle bend of the steel belt is the main factor that causes the wrong side of the steel pipe. In the forming of the spiral steel pipe, the sickle bend of the steel belt will continue to change into the angle, which will cause the weld gap to change, which will produce open seams, wrong edges and even set up. Side. It seriously affects the quality of the steel pipe.
2. The poor edge of the steel belt is another important reason for the wrong edge.
3. Due to the poor shape and size and accuracy of the tail of the steel band, it is easy to cause the steel strap to cause hard bending and cause the wrong edge.
4. When the tail tail of the steel band is large, if it is not handled properly when it is undermed, it will easily cause a large wrong edge.
