Petroleum Storage Tank Lining · Abu Dhabi
40m diameter petroleum tank interior lining. Polyurea with NSF-compliant formulation. Return to service in 18 hours.

Project Scale

Duration

The Challenge
Aging petroleum tank developed interior corrosion. Traditional epoxy systems require 7-10 day cure — incompatible with operational schedule. Chemical resistance critical: refined petroleum + wash chemicals exposure.
Our Solution
Abrasive blasted to Sa 2.5. Applied 3mm pure polyurea, chemical-resistant grade using JYYJ-H-V8T at 36 MPa with 10-inch PLC. Primer matched to carbon steel substrate. 42°C ambient required gel time tuned to 12 seconds.
What Pioneer Delivered
Not just a machine — a matched system, a trained crew on site, and after-sales backing end to end.
- An on-site survey of the 40m × 12m tank with dew-point and steel-temperature monitoring before any spray in the 42°C heat — so the lining bonds, not blisters.
- A single-source system — the JYYJ-H-V8T machine, matched primer and NSF-compliant polyurea tuned and warranted together, not sourced from three suppliers who blame each other.
- A spray crew trained for confined-space tank geometry and hot-climate application, pre-tuning gel time to 12 seconds at 42°C — the hard part of polyurea is the operator, and we own it.
- Holiday-tested QA across the full interior and a return-to-service plan built around the operator's schedule — the tank went back to refined petroleum in 18 hours, not 7-10 days.
- Ongoing remote support for ratio and temperature tuning, plus re-order of the exact matched NSF-compliant material — so the next maintenance cycle is a phone call, not a new project.
Execution Process
-
1 · Abrasive Blast to Sa 2.5
The tank interior is abrasive blasted to Sa 2.5 near-white, stripping corrosion and scale from the carbon steel and cutting an anchor profile. Dust is vacuumed and the surface checked dry before priming in the 42°C ambient.
-
2 · Primer & Climate Control
A primer matched to the carbon steel substrate is applied inside the recoat window for a chemical bond. Dew point and steel temperature are logged, and with 42°C ambient the polyurea gel time is pre-tuned to 12 seconds.
-
3 · Polyurea Lining Spray
3mm of chemical-resistant pure polyurea is hand-sprayed with the JYYJ-H-V8T at 36 MPa, the 10-inch PLC holding ratio and temperature steady across the 40m × 12m shell. The seamless monolithic film covers welds and corners with no pinhole-prone seams.
-
4 · Holiday Test & Return to Service
The cured lining is holiday-detected across the full interior to verify zero pinholes, then the NSF-compliant film is cleared for refined petroleum. The tank returns to service in 18 hours rather than the 7-10 days an epoxy system would need.
