Petrochemicals
Exchangers and reboilers for crackers, polymer plants and aromatics complexes worldwide.
What This Sector
Demands
Dolphin Group is an ADNOC-approved, ICV+ certified manufacturer of shell & tube exchangers, reboilers and condensers built to ASME Section VIII Div.1 and TEMA Class R & C for petrochemical service. Operating from its Mussafah, Abu Dhabi facility for over 40 years, it delivers exotic-alloy fabrication and retubing to crackers, polyolefin units and aromatics complexes worldwide.
Polymer fouling
Polymerising services foul exchangers aggressively, choking heat recovery and forcing early shutdowns. Restoring duty typically means in-place chemical cleaning or retubing rather than waiting for the next planned turnaround.
Cyclic thermal stress
Batch operations and unit trips cycle equipment through wide temperature swings, fatiguing tubesheets and joints. Over repeated cycles this fatigue is what drives premature joint failure on units not engineered for the duty.
Exotic material demands
Corrosive monomers and catalysts demand duplex, titanium or high-alloy construction with qualified welding procedures. Standard carbon steel construction cannot survive this service, so material selection has to be engineered against the specific process chemistry.
What We Deliver for
Petrochemicals
The specific heat exchange equipment and services we design, fabricate and maintain for this sector.
Proven in Petrochemicals
Real outcomes from real petrochemicals projects — not catalogue claims.
Polyolefins complex turnaround support
34 exchangers cleaned, tested and returned to service on schedule with full documentation.
ADNOC-approved, ICV+ certified
Qualified to the procurement standards ADNOC group companies require, with in-country value that scores directly on operator and EPC tenders. It is the same in-country value credential that ADNOC group companies weigh across every sector we serve.
Exotic-alloy fabrication in-house
Duplex, titanium and high-alloy construction with qualified welding procedures is built and tested at Mussafah — not subcontracted overseas. That in-house capability is what corrosive monomers and catalysts demand, since standard carbon steel cannot survive the service.

40+ years of fouling-service experience
Four decades of retubing and chemical cleaning polymerising and cyclic-duty exchangers inform every reboiler and condenser we build for petrochemical service. That experience delivered a full turnaround at a polyolefins complex — 34 exchangers cleaned, tested and returned to service on schedule with full documentation.
Frequently Asked Questions
Yes. We design and fabricate to ASME Section VIII Div.1 alongside TEMA Class R & C, matched to the polymerising and cyclic duty of crackers, polyolefin units and aromatics complexes.
Yes. We engineer geometry and surface finish against the specific fouling service, and support units with in-place chemical cleaning and retubing.
