Passivation, Cleaning & High-Velocity Flushing Services
Clean X Passivation supports pharmaceutical, biotech, CDMO, and data center facilities in Durham and the Research Triangle with mobile stainless steel passivation, CIP-based chemical cleaning, and high-velocity system flushing. Working from our Sanford, NC hub, we deliver ASTM A967/A380-compliant services with full GMP documentation and tight coordination around your production and commissioning schedules.
Why Durham & RTP Facilities Rely on Professional Passivation and Flushing
Durham sits in the heart of the Research Triangle Park (RTP), with high-value production assets including Biogen, Amgen, Pfizer, GSK, FUJIFILM Diosynth, KBI Biopharma, Catalent, RTI, IQVIA, and Duke Health research facilities. These sites depend on sanitary stainless systems, WFI and PW loops, critical utility piping, and chilled water networks that cannot afford rouge, microbial excursions, or corrosion-driven failures.
From new construction turnover to periodic derouging and re-passivation, improperly treated stainless and unflushed carbon-steel systems create:
Clean X Passivation brings pharma-grade passivation methods and data center–level flushing discipline together on every Durham project — with documentation built to satisfy ASTM A967, ASTM A380, and ASME BPE expectations.
We use Sanford, NC as the central hub and run daily routes into Durham and the wider RTP area. That keeps mobilization costs low while still delivering same-week or emergency response for:
- Planned turnarounds and shutdowns
- New equipment tie-ins and hot work repairs
- Post-weld passivation in live facilities
- Chilled water / condenser water start-up flushing
- Last-minute pre-inspection cleaning before FAT/SAT

Durham Pharmaceutical & Biotech Passivation – Summary Process
We apply the same disciplined methodology in Durham that we use on our pharma projects throughout the region. For full detail, see our pharmaceutical passivation services overview.
Pre-Operational Cleaning & Degreasing
Alkaline cleaning at 140–160°F removes fabrication oils, lubricants, polishing compounds, and organic residues that would block acid contact during passivation. This step aligns with best practices from our ASTM A380 cleaning guide.
Citric Acid Passivation & Derouging
4–10% citric formulations, sometimes blended with chelants, are circulated or applied in-place to remove embedded free iron and rouge while preserving chromium. Treatment parameters are tailored to Durham's specific asset and project requirements.
Final Rinse, Verification & Documentation
WFI / RO rinses to neutral pH, followed by water break, copper sulfate, and visual inspection. We deliver Durham-specific turnover packages with time/temperature logs, chemicals used, test results, and sign-offs ready for internal QA and regulatory review.
High-Velocity Flushing for Durham Data Centers & Utilities
New construction and retrofit work in Durham frequently includes large chilled water and condenser water networks feeding data centers, mechanical plants, and labs. If these lines are not properly flushed at velocity, you carry mill scale, welding slag, and construction debris straight into strainers, control valves, and cooling equipment.
Clean X Passivation brings high-flow pumps, temporary filtration, and calibrated instruments from Sanford to Durham to prove flow, velocity, and cleanliness against your specifications or contractor requirements.
- Temporary pump and hose manifolds sized for your system volume
- Velocity verification based on pipe size and specified ft/s
- Side-stream filtration to capture debris and fines
- Detailed flushing logs with differential pressure and turbidity notes
Durham Project Documentation & QA Support
Whether you are supporting an internal QA team, a global client, or a demanding GC, we build documentation that stands up during audits and turnover meetings.
Standard Turnover Package
- Scope of work and system boundaries
- Chemicals and concentrations (linked to SDS)
- Batch records and technician signatures
- Time/temperature logs for cleaning and passivation
- Flushing volumes and velocity verification notes
- Photos of critical areas (before/after)
QA / Validation Alignment
- ASTM A967/A380 references incorporated where applicable
- Support for IQ/OQ protocols on passivation scope
- Simple numeric references for change control tickets
- Electronic copies suitable for internal document control
- Clear acceptance criteria for future re-passivation decisions
