Service
Hydrojetting & Tube Cleaning
Hydrojetting services in Abu Dhabi: high-pressure water jetting to 2,800 bar restores fouled heat exchangers to design performance — without damaging the metal underneath.

How It Works
Ultra-high-pressure water — up to 2,800 bar — is delivered through rotating nozzles and rigid or flexible lances that strip deposits from tube bores and external surfaces.
- 1
Deposit type is assessed to set pressure, flow and nozzle selection.
- 2
Bundles are jetted tube-by-tube with rigid or flexible lances; automated indexing ensures no tube is missed.
- 3
Shell-side and external surfaces are jetted with rotating heads.
- 4
Cleanliness is verified visually and, where required, by borescope before sign-off.
Built to
Solve
Engineered against the specific failures that cost operators downtime, contamination or wasted energy.
Asset protection
Mechanical rodding and aggressive chemicals damage tube surfaces; water jetting removes deposits without metal loss, preserving wall thickness and extending the bundle's remaining service life.
Process integrity
Partially blocked tubes create local velocities and dead zones that accelerate corrosion and under-deposit attack — the fouling that is left behind does more damage than the fouling that is removed.
Operational efficiency
A fouled exchanger can lose half its duty — heat you then buy back as fuel. Cleaning is the cheapest energy project in the plant, with payback measured in weeks rather than years.
Why Dolphin Group for
Hydrojetting & Tube Cleaning
Cleaning informed by engineering
We know what the exchanger should do thermally — cleaning is signed off against performance, not appearance.
Turnaround-proven crews
Multi-unit cleaning campaigns executed inside tight shutdown windows with documented coverage.
One contractor, full scope
Cleaning, inspection, repair and testing under one mobilisation — no interface losses between vendors.
Key
Benefits
What sets hydrojetting & tube cleaning from Dolphin Group apart, in specific and measurable terms.
- 1
Restores design performance
Restores heat exchange performance to near-design values without touching the tube metallurgy.
- 2
High-pressure capability
Up to 2,800 bar removes hard scale and polymer coke that lower pressures leave behind.
- 3
No surface damage
No mechanical or chemical damage to tube surfaces — wall thickness stays exactly as it was.
- 4
Full documented coverage
Automated lancing delivers consistent, 100% tube coverage, documented tube by tube.
- 5
Site or workshop execution
Delivered worldwide, on site or in the workshop, whichever the outage schedule demands.
- 6
Controlled wash-water handling
Environmentally controlled wash-water handling, collected and disposed of to standard.

View SectorFrequently Asked Questions
No — pressure and nozzle selection are matched to metallurgy and deposit; water jetting removes fouling without the metal loss of mechanical cleaning.
Yes — up to 2,800 bar with appropriate nozzles removes calcite, sulphate scale and polymer coke.
Both. Site crews clean in place or at grade during turnarounds; pulled bundles can be cleaned and inspected at Mussafah.
Visual and borescope verification per tube, plus before/after performance data where required.
Automated lancing typically cleans a mid-size bundle within one shift; campaigns are planned to your outage schedule.
Yes — controlled-pressure external jetting cleans finned surfaces in place without bending fins.
Containment and disposal are handled per site environmental requirements as part of our scope.
