There are many bad conditions to be adjusted for welded pipe machines, such as scratches, drilling pipes, straightening adjustments, etc.
There are many bad conditions to be adjusted for welded pipe machines, such as scratches, drilling pipes, straightening adjustments, etc.
When scratches occur, this situation mainly occurs on both sides of the transverse and longitudinal axes of the pipe section, and is mostly caused by the edges of the flat roller and vertical roller pass patterns. At this time, we need to check whether the roller is displaced, whether the bearing is damaged and whether the machine parameters are adjusted. Although this is a phenomenon that should not occur artificially, it is unavoidable in reality.
Drill pipe problems are usually rare, and the probability of this happening is relatively low. If this occurs it may be due to the poor rigidity of the thin-walled tube. If the tube wall is thin, it is easy to be bitten by the roller. Generally, such situations need to be checked to see if the bearing is damaged and the hole pattern center is not correct.
For the straightening adjustment, we need to pay attention to the stress direction to avoid the gap between the roller edges. If the outer diameter of the pipe exceeds the tolerance, straightening rollers are not required to participate in the sizing adjustment of the pipe as much as possible. After the adjustment, it is also necessary to check: the rotation seam of the pipe, the poor cooling of the pipe, the heating of the weld, the damage of the bearing of the straightening roller, the stability of the straightening roller mechanism, the non-attachment of the straightening roller to the pipe wall, and the contact between the components of the flying saw equipment and the pipe to ensure that the fault can be completely solved.
