Steel & Metallurgy
Steel plant heat exchangers and cooling equipment: furnace cooling, quench systems and dust-laden gas coolers built for the hardest environments in industry.
What This Sector
Demands
Dolphin Group is an ADNOC-approved, Local+ Certified manufacturer of ASME U2 Section VIII Div.1 and TEMA Class C furnace cooling elements, water-cooled panels and gas coolers for steel and aluminium producers. Operating from its Mussafah, Abu Dhabi facility for over 40 years, it refurbishes abrasion- and thermal-shock-rated cooling equipment worldwide.
Thermal shock cycling
Furnace cooling circuits cycle violently with every heat; weld quality and water chemistry decide element life. A weld that would hold under steady-state duty can still crack under repeated furnace-heat cycling if it is not engineered for the shock.
Abrasive, dust-laden gas
Process gas coolers erode from the inside; geometry and material must be chosen for wear, not just duty. A cooler sized only for thermal performance and not for erosion will wear through well before its rated life.
Continuous casting uptime
Mould and machine cooling failures stop casting instantly — redundancy and fast exchange matter, since there is no graceful degradation once a cooling circuit fails on the casting line.
Why Operators Choose
Dolphin Group
ADNOC-approved, Local+ Certified
Qualified to the procurement standards ADNOC group companies require, with in-country value that scores directly on steel and metallurgy producer tenders.
Engineered for thermal shock and abrasion
Weld quality, water chemistry and wear-resistant geometry are engineered at Mussafah for furnace cycling and dust-laden gas — not just steady-state duty.
40+ years of continuous-operation refurbishment
Four decades of refurbishing cooling circuits during planned mill outages inform every furnace cooling element and gas cooler we build for steel service.
Frequently Asked Questions
Yes. We design and fabricate to ASME U2 Section VIII Div.1 alongside TEMA Class C for furnace cooling elements, water-cooled panels and gas coolers.
Yes. An EAF cooling circuit refurbishment package — water-cooled panels and exchangers — was completed during a planned mill outage.
Weld quality and water chemistry are engineered against the violent cycling every furnace heat imposes, since these decide element life.
Yes. Geometry and material are selected for wear resistance, not just thermal duty, since dust-laden gas erodes coolers from the inside.
Yes. We engineer mould and machine cooling equipment with redundancy and fast-exchange capability in mind, since a failure stops casting instantly.
Yes. Plate and shell & tube exchangers are supplied alongside furnace cooling elements and gas coolers for steel and aluminium producers.
Yes. Dolphin Group is ADNOC-approved and Local+ Certified — one of roughly 70 Local+ Certified companies in the UAE.
