ORM - Offline Rectifying Machine
The Offline rectification machine is used for pipe end calibration. By calibration we mean grinding of pipe spigot end, execution of grooves for sealing rings and cutting at predefined lengths.
To cover the full production range, two different systems are used. Up to pipe ND 900, calibration is performed on the pipe clamped between the two cones, whilst from pipe ND 1000 up to ND 2000, pipe calibration is performed before its extraction from the mandrel. In both cases, the pipe spigot end with »O« ring grooves is finished off simultaneously by a set of grinding wheels. This machine is equipped with a dust suction system. Dust produced during calibration is conveyed through suction ducts to the dust filters.
