High-Velocity Flushing
Turbulent flow flushing at 5-10 ft/sec removes weld slag, debris, and contaminants from new piping systems. Essential for construction commissioning and system startup.
Industrial Cleaning & CIP
Comprehensive cleaning services including clean-in-place systems, alkaline degreasing, and chemical cleaning. We match the right chemistry to your application.
Derouging Services
Professional rouge removal and re-passivation. Rouge (iron oxide contamination) forms from inadequate passivation or aggressive CIP chemicals. We restore surfaces to a properly passivated state.
Hydrostatic Testing
Pressure testing services for piping systems, vessels, and equipment. We verify system integrity with chart-recorded results and complete documentation packages for commissioning and compliance.
Pharmaceutical Passivation
GMP-compliant passivation for WFI systems, bioreactors, and clean steam. We understand FDA audits and deliver IQ/OQ documentation packages that keep your facility audit-ready.
EV Battery & NMP Systems
Specialized expertise in NMP solvent systems, electrode coating lines, and battery cell production equipment. We've worked with Toyota Battery Manufacturing, helping build the future of electric vehicles.
Data Center & AI Cooling
AI and HPC facilities need clean cooling loops. We protect microchannels, cold plates, and rear-door heat exchangers with proper flushing protocols designed for sensitive cooling infrastructure.
The CXP Passivation Process
Click each step to learn more about our proven methodology.
Step 1: Inspection & Assessment
Before any work begins, we thoroughly survey all welds, surfaces, and system components. This initial assessment identifies contamination levels, surface conditions, and any special considerations for your system.
- Visual inspection of all welds
- Surface condition assessment
- Contamination identification
- Custom protocol development
Step 2: Alkaline Degreasing
Oils, greases, and organic contaminants are removed using alkaline cleaning solutions. This critical step ensures the passivation chemistry can properly contact the stainless steel surface.
- Removes oils and greases
- Temperature controlled
- Prepares surface for acid
- Thorough rinse follows
Step 3: High-Velocity Flushing
Water is circulated at 5-10 ft/sec to create turbulent flow that physically removes weld slag, debris, and loose particles. This mechanical cleaning is essential before chemical treatment.
- 5-10 ft/sec flow rates
- Turbulent flow regime
- Multi-stage filtration
- Flow data logging
Step 4: Acid Passivation
Citric or nitric acid solution is circulated to remove free iron and enhance the chromium oxide passive layer. Temperature, concentration, and contact time are precisely controlled per ASTM standards.
- Citric or nitric acid
- ASTM A967 methods
- Time/temp controlled
- Concentration logged
Step 5: Neutralization & Rinse
After passivation, the system is thoroughly rinsed and neutralized to remove all acid residue. pH is monitored to confirm complete neutralization before proceeding to verification.
- Complete acid removal
- pH verification
- Multi-stage rinse
- Conductivity testing
Step 6: Verification & Documentation
Passivation effectiveness is verified using copper sulfate or ferroxyl testing. Complete documentation packages include batch records, test results, before/after photos, and chemical certifications.
- Copper sulfate testing
- Ferroxyl testing available
- Complete batch records
- IQ/OQ packages
