Corrosion is a persistent challenge for industrial equipment such as boilers, pressure vessels, heat exchangers, and other process plant components. These assets operate in harsh environments and are often exposed to moisture, oxygen, and other corrosive elements. Protecting these components requires a specialized solution that safeguards hollow spaces and does not affect thermal transfer properties or operational performance.

This is where Vapor Corrosion Inhibitor (VCI) powders provide an ideal solution. They are versatile, efficient, and tailored for industrial preservation without mechanical cleaning during equipment reactivation.

Challenges in Corrosion Protection

Protecting equipment like boilers and heat exchangers demands unique considerations:

  • Hollow Space Protection: Ensuring that every corner, including hard-to-reach areas, is shielded.
  • Thermal Efficiency: Maintaining heat transfer properties without adding thermal resistance.
  • Dry and Removable Protection: Ensuring that the protective layer is easy to remove before the equipment becomes operational.

The intricate designs and large surface areas of such equipment further complicate corrosion protection. VCI powders address these challenges with precision.

What Are VCI Powders?

Vapor Corrosion Inhibitor (VCI) powders are specialized formulations that evaporate and diffuse into enclosed spaces, forming a protective molecular layer on metal surfaces. This layer prevents moisture, oxygen, and other corrosive agents from reacting with the metal, thereby inhibiting corrosion.

Key Features of VCI Powder

  • Non-Silica Formulation: Free from silica to ensure safety and compatibility with sensitive equipment.
  • Nitrite-Free Chemistry: Environmentally friendly and safer for operators.
  • MIL-I-22110 Specification Compliance: Adheres to stringent military-grade standards.
  • Crystalline Structure: Enhances vaporization and ensures even distribution.

How VCI Powder Protects Process Equipment

VCI powder is applied to hollow components using techniques like spraying, fogging, pouring, or rolling. Once in place, the powder begins to evaporate, releasing corrosion-inhibiting vapors. These vapors condense on metal surfaces, forming a protective barrier that penetrates even the most inaccessible areas.

Application Techniques

1. Spraying or Fogging

Using air spray or compressed air, the VCI powder is fogged into hollow spaces. This method ensures a uniform layer of protection across internal surfaces.

2. Pouring and Rolling

In large vessels or equipment, the powder can be poured and rolled, distributing it evenly across surfaces.

3. Hydro Testing and Aqueous Coating

For applications requiring wet protection, the VCI powder can be dissolved in water at concentrations of 2-5%. This creates a protective aqueous coating that is ideal for hydro testing or temporary storage.

Advantages of VCI Powder Application

  • Ease of Use: Quick and efficient application methods reduce downtime.
  • No Residue Left Behind: Easily removable without the need for mechanical cleaning.
  • Comprehensive Protection: Reaches every crevice, including hard-to-access areas.
  • Multi-Metal Compatibility: Protects carbon steel, alloy steel, and stainless steel.
