Piping Asset Preservation for Mechanical Equipment

Mechanical assets like pumps and compressors have complex internal surfaces that standard storage methods can't reach. P3’s advanced VCI fogging and encapsulation systems ensure your equipment remains in factory-new condition, even in the harshest staging environments.

The P3 preservation system utilizes the "Fog and Seal" approach. By aerosolizing specialized VCI inhibitors, we create a protective vapor that migrates to every internal nook and cranny. When sealed with our flangeDOTS®, this vapor is "locked in," creating a self-healing protective atmosphere that requires zero maintenance for up to 24 months.

Materials:

• Graco Ultra 395 Airless Sprayer or equivalent with Graco Tip LTX#321 or equivalent (.021 max orifice)
• Intrinsically safe exhaust fan or blower
• VCI Test Kit
• Flexible ducting to connect to fan/blower
• Respirator, Cartridge, Half Face: 3M 3200 or 6500 series, or equivalent
• Project approved foggable corrosion inhibitor
• 3M 483 Polyethylene Tape or equal
• flangeDOT+VCI or flangeDOT+Tag+VCI
• Thermo Anemometer

Preservation Process:

1. 1. Preparation & Ventilation: Set up an intrinsically safe exhaust blower and flexible ducting. This ensures airflow through the equipment to carry the VCI molecules to the outlet.

   2. Verification Setup: Attach a VCI test strip to the outlet. Use a thermo-anemometer to verify a flow rate of approximately 100 CFM.

   3. The Fogging Process: Using an airless sprayer (e.g., Graco Ultra 395) with a specialized fine-mist tip, introduce the foggable corrosion inhibitor through the inlet.

   4. Confirmation: Once the VCI test strip at the exhaust point shows a positive reaction, the internal environment is fully saturated.

   5. Final Encapsulation: Immediately seal all inlets, outlets, and exhaust ports using flangeDOTS® +VCI or flangeDOTS® +Tag. This traps the vapor inside, maintaining the protective concentration.

   6. Exterior Protection: Secure all connections with 3M 483 Polyethylene Tape or equivalent to ensure the system is airtight and weather-resistant.

*Ensure manufacturers short/long term preservation and storage procedures are followed...  Follow OEM recommendations where possible*

Key Benefits:

• 100% Surface Coverage: Vapor reaches areas that liquid inhibitors simply cannot, protecting seals, bearings, and machined internals.
• Easy Commissioning: Unlike grease or oil-based preservatives, VCI vapors do not need to be flushed out before the equipment is put into service.
• Two-Year Protection: A single application provides up to 24 months of "set-and-forget" preservation.
• FME/FOD Compliance: Our encapsulation system doubles as a Foreign Material Exclusion (FME) barrier, keeping dust and debris out.
