Shutdown Blasting Sequence
Refinery maintenance is governed by explosion-risk control. To maintain surface preparation production in hydrocarbon-rich zones, the technical approach must shift from traditional dry blasting to intrinsically safe wet methodologies.
1. Spark-Safe Preparation
Utilization of Vapor Abrasive Blasting to suppress 92% of dust and significantly reduce spark risk during external shell cleaning in live tank farms.
2. Internal Tank Lining (Sa 3.0)
Achieving Sa 3 White-Metal finish for internal floor and lower-ring zones using high-velocity Garnet to ensure absolute adhesion for crude-oil resistant epoxies.
3. Pipeline Internal Restoration
Using Internal Pipe Blasting Tools to remove heavy petroleum scale and rust from connector lines before applying 360° internal linings.
Confined Space Safety
Internal tank work demands 100% reliability in life support. Our Breathing Air Filters provide Grade D air to Blast Helmets, ensuring operators are shielded from toxic coating vapors and fine particulates in zero-ventilation zones.
Corrosion Verification
Refinery specs are non-negotiable. Holiday Detectors are mandatory for post-lining audits to detect microscopic pinholes that would otherwise lead to rapid localized pitting and tank wall failure.
Critical Asset Technical Audit
- Vapor Blasting: For external tank shell restoration in live units.
- 360° Coating: Internal Pipe Coaters for consistent WFT in feeder lines.
- Profile Check: Verifying anchor pattern for high-build chemical linings.
