The Anatomy of a
Pressure Vessel
Shell
The cylindrical pressure boundary, rolled and welded from plate to ASME U2 Section VIII Div.1.
Drag to rotate
For representation purposes only.
Built to
Solve
Engineered against the specific failures that cost operators downtime, contamination or wasted energy.
Asset protection
A pressure vessel is a stored-energy hazard — design or weld shortcuts are not discovered until failure, and failure is catastrophic. ASME U2 Section VIII design and certified welding are the only acceptable standard.
Process integrity
Separator and drum internals decide downstream equipment life; poor vessel hydraulics cascade through the whole train, showing up as carryover, fouling and premature wear well beyond the vessel itself.
Operational efficiency
Overseas vessel procurement adds months of schedule and freight risk to projects that a UAE fabricator eliminates. In-region fabrication also means faster response when a vessel needs modification or repair.
Why Dolphin Group for
Pressure Vessels
Code authority in-country
ASME U2 and R Certificates of Authorization held at Mussafah — new construction and repair, stamped locally.
Heavy fabrication capacity
25,000 m² of workshop with rolling, PWHT and lifting capacity for vessels beyond 100 tonnes.
ADNOC & Local+ standing
Vendor-approved and Local+ Certified — your vessel procurement scores on local value while cutting schedule.
Key
Benefits
What sets pressure vessels from Dolphin Group apart, in specific and measurable terms.
- 1
Certified fabrication
ASME U2 Stamp fabrication with full code data reports issued with every vessel.
- 2
Full material traceability
Full material traceability on every pressure part, from plate to nozzle.
- 3
Sour service capable
PWHT, impact-tested and NACE MR0175 sour service capability for H₂S-bearing streams.
- 4
No subcontract chain
In-house rolling, welding, NDT and hydrotest — one workshop, one schedule, no subcontract handoffs.
- 5
Faster project schedules
UAE fabrication removes months of freight and customs delay from the project schedule.
- 6
R-stamp repairs
Repairs and alterations of existing code vessels, keeping assets in service instead of replacing them outright.

Design and Manufacturing
ASME U2 Section VIII Div.1 design in PV Elite through U-stamped delivery, with in-house rolling, welding, NDT and hydrotest under one roof.
Refurbishment
ASME U2 R-stamp repairs and alterations that keep an existing vessel's certification intact instead of replacing it outright.
Servicing
NDT, hydrostatic testing and internals inspection that confirm a vessel is fit for continued service before it goes back on line.
Long Term Contracts
Scheduled statutory inspection programmes that keep vessel condition and code documentation current across every turnaround.
