Vapor Corrosion Inhibitors

Vapor Corrosion Inhibitors

MATCOR offers Vapor Corrosion Inhibitor (VCI) solutions — advanced chemical compounds that diffuse through confined spaces and bond with metal surfaces, creating an invisible barrier against corrosion. Delivered through MATCOR’s partnership with Zerust® Integrity Solutions, VCIs provide a flexible, cost-effective option for protecting pipelines, tanks, and other metal assets — as a standalone solution or alongside cathodic protection.

Vapor Corrosion Inhibitors Key Benefits

Compatible with other CP methods
High return on investment
Real-time monitoring available
Biodegradable, non-toxic options
AMPP and PHMSA approved
Easily removable if needed

Vapor Corrosion Inhibitors Components

Available in multiple forms, including films, papers, powders, liquids, and emitters — adaptable to a wide range of industrial applications.

Delivered through MATCOR’s partnership with Zerust® Integrity Solutions, combining proven Zerust VCI chemistry with MATCOR’s corrosion engineering expertise.

Vapor Corrosion Inhibitors Specifications

  • Typical protection duration: 3–5 years, longer under optimal conditions
  • Monitoring methods: coupons, ER probes, UT probes; remote monitoring units (RMUs) available
  • Recognized under API 651 (alternative where CP is unsuitable) and API 2610 (use under tank bottoms)
  • Compatible with impressed current cathodic protection systems — may alter native steel potential, so factor this in per NACE SP0193 when selecting CP criteria

Vapor Corrosion Inhibitors Design

Applications

  • Oil and Gas: protects internal pipeline surfaces after hydrotesting and safeguards tank bottoms from localized corrosion
  • Manufacturing and Industrial Equipment: shields components during storage, shipping, or idle periods
  • Marine and Offshore: mitigates corrosion from saltwater and high-humidity environments
  • Aerospace and Automotive: protects critical systems like engines and fuel tanks during long-term storage
  • Infrastructure and Utilities: prevents corrosion in water pipelines, bridges, and utility equipment

Often used to complement cathodic protection (CP) systems, and recognized as a standalone solution in scenarios where CP isn’t feasible.

Vapor Corrosion Inhibitors Installation

  • Simple application: no heating required; mix with potable water and inject through vent pipes for efficient distribution
  • Non-invasive: no disassembly needed, practical for hard-to-reach areas
  • Removable: can be washed out if needed, offering flexibility for future maintenance
  • Replenishment timing depends on environmental conditions and depletion rate: influenced by chime leakage rate, operating temperature, substrate properties, and initial VCI quantity applied
