Project Name: Poatina Penstock
Location: Tasmania
Customer: Lothway TBS
Total Area to Refurbish: 1.5km (0.3 mile) pipeline, 3.3m (10ft) diameter

• Complete blast/paint inside & out
• 1km of pipe had external stiffeners (upside down C-section wrapped around pipe)
• 100 meter vertical 90 degree drop at end, and a long stretch of pipe at 32 to 38 degree drop

Coating Removed:  Coal Tar – first pass with UHP water, second pass for cleanliness, flash rust removal and to effect a profile – RIPT dry abrasive blasting.

Equipment Set-up: 3 nozzle Robotic Internal Pipe Tool (RIPT) with bulk pot and 2″ blast hose, GMA Speedblast garnet

Environment:  Very Cold

Previous Performance Results:  15 m²/hour (161 ft²/hour)

RIPT Improved Results:  90 m² (968.75 ft²) per hour, more consistent blast pattern, reduced abrasive consumption
