Oil & Gas
Heat exchangers for oil and gas in the UAE: thermal equipment engineered for upstream, midstream and refining service, built and serviced in Abu Dhabi.
What This Sector
Demands
Oil & gas processing involves demanding thermal conditions across upstream production, gas processing and refining. Equipment must maintain reliable thermal performance while managing pressure, temperature, fouling and maintenance requirements.
Sour service conditions
H₂S, CO₂ and chlorides accelerate corrosion and threaten exchanger reliability. Dolphin Group matches materials and manufacturing to the process conditions to keep sour service equipment reliable.
Shutdown-critical lead times
Exchanger availability can directly affect plant operation and turnaround schedules. Dolphin Group manufactures locally, including reverse-engineered and drop-in replacements, to keep those schedules on track.
Fouling and thermal performance
Fouling raises pressure drop and cuts thermal efficiency across crude preheat systems, gas coolers and other process applications. Dolphin Group designs for fluid properties, fouling characteristics and maintenance needs from the outset.
