Equipment
Shell & Tube Heat Exchangers
TEMA-compliant, ASME U2-Stamped shell & tube heat exchangers designed, fabricated and tested in Abu Dhabi, the workhorse of process heat exchange, built for service worldwide.

The Anatomy of a
Shell & Tube Heat Exchanger
Tube Bundle
The tube bundle is the set of parallel tubes that carries the tube-side fluid through the exchanger. The shell-side fluid flows around the outside of these tubes, so heat transfers across the tube wall without the two fluids ever mixing. This tube wall is the exchanger's primary heat transfer surface.

Built to
Solve
Engineered against the specific failures that cost operators downtime, contamination or wasted energy.
Asset protection
The right exchanger for your duty runs cooler, fouls slower and lasts longer, protecting the pumps, seals and downstream equipment that depend on it. Getting the specification right upfront avoids an unplanned shutdown later.
Process integrity
Tube leaks cross-contaminate product and utility streams. Correct TEMA type, tubesheet design and weld quality are what stand between two fluids: get any one wrong and the exchanger becomes the point of failure for the whole process.
Operational efficiency
Every degree of lost approach temperature is bought back with fuel or power. Precision thermal design, verified in HTRI before fabrication, pays for the exchanger many times over its operating life.
Why Dolphin Group for
Shell & Tube Heat Exchangers
ADNOC-approved, Local+ certified
Qualified to the world’s most demanding procurement standards, one of ~70 Local+ companies in the UAE.
Design-to-delivery under one roof
HTRI thermal design, ASME U2 manufacturing, NDT and testing all happen in our Mussafah facility, one accountable party.
Four Decades of Proven Reliability
Four decades of exchangers operating in some of the harshest conditions on earth inform every material and design decision we make.
Key
Benefits
What sets shell & tube heat exchangers from Dolphin Group apart, in specific and measurable terms.
- 1
Certified manufacturing
ASME U2-Stamped manufacturing with full material traceability. Every certificate ships with the unit, not on request after the fact.
- 2
Verified thermal design
In-house HTRI thermal design: guaranteed performance, not catalogue guesses. Duty is verified before a single plate of steel is cut.
- 3
High-duty rated
Design pressures beyond 100 bar and temperatures beyond 500°C. Severe-duty specification is standard practice here, not a special order.
- 4
Metallurgy range
From carbon steel to duplex, titanium, and clad construction, matched to the fluid rather than defaulted to whatever is in stock.
- 5
Drop-in replacement
Replacement bundles reverse-engineered from existing units, with no waiting on OEM drawings that may no longer exist.
- 6
In-house schedule control
Design and manufacturing under one roof means no subcontracted queue or handover delay.

Design and Manufacturing
We design every exchanger from scratch in HTRI, then manufacture it under ASME U2 code stamp at our Mussafah workshop, with full material traceability from first plate to finished unit.
Refurbishment
When an exchanger falls short of design performance, we extract the bundle, retube and reface the tubesheet to bring it back — backed by ASME U2 R-stamp code repairs where certification must stay intact.
Servicing
Hydrojetting, chemical cleaning, and eddy current or IRIS tube testing quantify how much life an exchanger has left before any repair scope is agreed.
Long Term Contracts
Scheduled inspection and maintenance programmes track exchanger performance across every turnaround, catching issues on record rather than at the point of failure.

View SectorFrequently Asked Questions
For fouling on both sides, a floating head (AES/AET) allows full bundle removal and mechanical cleaning. If only the tube side fouls, a fixed tubesheet with cleanable straight tubes is more economical.
Yes. We reverse-engineer from the physical unit and nameplate data, verify thermal performance in HTRI, and fabricate a dimensionally identical drop-in replacement.
Titanium, super duplex, and 90/10 copper-nickel are our standard recommendations, selected by chloride level, temperature and velocity.
Yes. Dolphin Group holds ASME U2 and R Certificates of Authorization, so new construction and repairs are code stamped with full data reports.
Typically 8–16 weeks depending on size and metallurgy, significantly faster than overseas fabrication once shipping and customs are counted.
Yes. Spare bundles are a standard scope, and we hold dimensional records of every bundle we build for fast repeat orders.
Yes. We design and fabricate to API 660 supplementary requirements alongside TEMA Class R for petroleum service.
