Shotblasting machines for external pipes

These automatic units are perfectly suitable for continuos blasting of steel pipes external surface, in accordance with customer particular requirements and also in line with further surface treatment equipment. Turbines are placed on central cabin roof.
Entry and exit pre-chambers, provided with rubber diaphragms, avoid shot losses from the equipment. The pipes simultaneously rotate and longitudinally move by means of special motorised biconical rollers. The rollers are controlled by a motor group provided with an inverter in order to adjust the longitudinal speed of the pipes in accordance with rust conditions of workpieces and final required blast grade.
