Pipetech were tasked to AquaMill® 21 flexible small bore pipes ranging from 1.315” to 1.66” internal diameter. Total length of each pipe was 10 metres.
Pipetech were approached to carry out descaling of flexible small bore pipework. Previous attempts using traditional retro jetting were found to be ineffective at removing the hard scale from the pipe wall. Pipetech set up an 8mm Aqua Milling® line and Aqua Milled the pipes at 650 Barg until returned waters ran clear. Post cleaning inspection found all lines to be visually acceptable and the pipework was ready to return to service.
Challenges
Removal of hard scale build up traditional retro jetting techniques could not achieve.
Achievements
- Successful polishing of scale from small bore pipework.
- All spent water was fully contained and filtered prior to disposal.
Benefits
Performance – Fully contained remotely operated cleaning system carried out cleaning of difficult pipework were other methods had failed.
Flexibility – Carried out workscope at onshore premises with no impact on client operations.
