The reason for the wrong side

In the production of spiral steel pipe plant, the wrong side often occurs, and its influence factors are many.In the production practice, the steel pipe is often degraded by the error edge.Therefore, it is necessary to analyze the causes of the wrong side of spiral steel pipe mill and its preventive measures.In the forming process of spiral steel pipe factory, the scythe bend of steel belt will change the forming Angle continuously, which will lead to the change of welding seam clearance, thus resulting in the opening, the wrong side and even the side.It seriously affects the quality of steel pipe, so it is an effective way to reduce the wrong side of steel belt scythe in the production process to observe the scythe bending of steel belt after it is rolled and unrolled.
