- 12-station copper tube blast cleaning machine
Blasting reduces the carbon content of the surface and enhances the formation of a “malachite layer" protecting against corrosion.
Tube & Pipe Blast Machines
Unlike other hollow bodies tubes and pipes can be processed horizontally because abrasive and compressed air may escape at the rear end.
That is why our Problast PowerPacks with closed-circuit system are the ideal equipment to blastclean, descale and activate the insides of tubes and pipes.
- Untreated pipe
- Blast-cleaned pipe
There are two different blasting methods:
1. Blow-through method
In the easiest case, such as the blasting of coils, a blast nozzle is connected to the forward end and a recovery hose to the rear end of the tube.
When straight tubes are to be processed the rear end of the tube is led to a recovery box where the abrasive is collected and recycled.
- Problast PowerPack with adapters for coils
Blasting reduces the carbon content of the surface and enhances the formation of a “malachite layer" protecting against corrosion.
Half-hard copper tubes are cleaned and roughened using chilled cast iron grit or aluminium oxide.
Axle tubes are descaled after heat treatment:
- Combined inside/outside blasting system for axle tubes
- Interior view of axle tube before and after blasting
2. Lance method
For larger tube diameters special blast nozzles are fitted to a lance which is inserted in the tube:
- Pipe cleaner with lance carriage
The rear end of the pipe is positioned in an abrasive recovery box.
A blast lance is inserted cleaning the pipe while it retracts.
- Blast lance with rotating blast head
Either the pipe, the lance or the blast head is rotated.
Multi-nozzle blast heads are available for high-production needs.
