- Operator friendly
- Automated and remote controlled process
- Low noise level in comparison to manual blasting
- Maintenance friendly
- Quick return on investment
How It Works:
The Field Joint blasters are based on horseshoe shape devices configured for up to four vacuum blast nozzles. The system needs to be placed onto and taken from the joint area by means of e.g. a crawler truck with loader arm. After placement the blaster clamps itself into position. Once the position is secured the joint is blasted. The blast nozzles are paired up, each pair blasts one half of the joint area. To ensure a tight seal of blast nozzles on the pipe, they are equipped with brush seals.
The Full Scope:
- Light weight frame
- Vacuum blast system with up to four blast nozzles
- Abrasive reclaim system
- Brush wear compensator
