Corrugated compensator in the molding process, the material occurs cold work hardening phenomenon, the strength will be strengthened, the corrugated pipe pressure-bearing capacity increased. However, because the corrugated compensator is split installation, higher formation stress, it is difficult to ensure the waveform shape of the corrugated compensator after splitting. The corrugated compensator must be processed to eliminate stress.
Corrugated compensator wire cutting processing in order to reduce the size of the joints, all parts of the split processing, are used wire cutting process. Line cutting money, first mark, then line cutting, cut and assembled together, in order to facilitate on-site grouping. Compensation alignment corrugated compensator line cutting, should be grouped together again, along the side of the three butt longitudinal seams are spot welded alignment liner, and mark, and then separate, grinding from the welded bevel.
