Emergency Equipment Repair / Replacement
Emergency heat exchanger repair in the UAE: round-the-clock breakdown response for heat exchangers and pressure equipment, with in-house fabrication behind it when a repair is not enough.

How It Works
Emergency work follows the same sequence as planned work, compressed. The aim is to reach a defensible repair-or-replace decision quickly, then execute it without a second mobilisation.
- 1
Call-out is received and an engineer is dispatched to establish scope on site.
- 2
The unit is isolated, opened and inspected: leak location, tube condition and wall thickness are recorded.
- 3
A repair-or-replace recommendation is issued with the evidence and the time implications of each option.
- 4
Temporary measures such as tube plugging restore service where a full repair cannot fit the available window.
Built to
Solve
Engineered against the specific failures that cost operators downtime, contamination or wasted energy.
Asset protection
An unplanned exchanger failure rarely stays contained. Thermal shock, overpressure and emergency shutdowns propagate damage into adjacent equipment, so the cost of the outage is set by how quickly the first failure is isolated and corrected.
Process integrity
Running a damaged unit on reduced duty to reach a scheduled window is a decision made without data. Leak location, tube condition and remaining wall thickness determine whether that is safe, and only inspection establishes them.
Operational efficiency
Most of an emergency outage is waiting, not working: waiting for assessment, for a decision, for material, for a fabricator with capacity. Compressing that queue matters more to total downtime than the speed of the repair itself.
Why Dolphin Group for
Emergency Equipment Repair / Replacement
Decision and execution in one place
The engineers who assess the failure work for the same company that fabricates the replacement, removing the handover that usually costs the most time.
Manufacturing capacity, not just labour
ASME U2 fabrication in Abu Dhabi means replacement is a scheduling question rather than an import lead time.
Forty years of failure patterns
Most emergencies are a recognisable failure mode seen before, which shortens diagnosis when diagnosis is the bottleneck.
Key
Benefits
What sets emergency equipment repair / replacement from Dolphin Group apart, in specific and measurable terms.
- 1
Round-the-clock response
A 24/7 call-out route into engineers who can assess and act, not just log the call.
- 2
Assessment before commitment
A documented repair-or-replace recommendation with the evidence behind it, so the spend is justified before it is made.
- 3
Fabrication behind the service
Our own ASME U2 workshop means a replacement can start immediately rather than entering an OEM queue.
- 4
Temporary measures that are honest
Plugging and interim repairs are supplied with their limits stated, including how long they can be relied on.
- 5
Reverse engineering for obsolete units
Equipment whose original maker no longer supports it can still be rebuilt from the unit itself.
- 6
Failure evidence captured
What failed and why is recorded during the repair, which is what makes the next failure preventable.

Our emergency line operates 24/7 and an engineer is dispatched to establish scope on site. Response time depends on location and access, and we confirm a realistic arrival time when the call is taken rather than after mobilising.
Sometimes, and that decision should follow inspection rather than precede it. Once leak location, tube condition and remaining wall thickness are known, we state whether interim running is safe and for how long.
Plugging seals a failed tube at both ends so the unit can return to service with slightly reduced surface area. It suits isolated failures in a bundle with life left, and becomes the wrong answer once the plugged count starts costing meaningful duty.
As a working guide, plugging beyond roughly ten percent of tubes begins to cost noticeable duty, though the real limit depends on the design margin of the unit. We calculate the effect for your specific exchanger rather than applying the rule blindly.
Yes. Most of our repair work is on other manufacturers equipment, including units whose original supplier no longer supports them.
We reverse-engineer it from the damaged unit and fabricate a replacement under our own ASME U2 stamp, which avoids the import lead time that usually dominates a replacement schedule.
Yes. As-found condition, work performed, materials used and test results are documented, which matters both for your integrity records and for preventing a repeat.
Use the emergency contact route on our contact page. Have the equipment tag, service, and a description of the symptom ready, as that determines who we dispatch.
