Corrosion Challenges in Process Industries

Process facilities may expose metal equipment to water, steam, condensation, salts, acids, alkalis, corrosive gases, chemical vapors, elevated temperatures, and changing operating conditions. These exposures can attack both operating equipment and assets temporarily taken out of service.

Corrosion may affect piping, tanks, pumps, valves, heat exchangers, boilers, cooling systems, electrical equipment, structural steel, and stored replacement parts. If corrosion is not controlled, facilities may experience leaks, product contamination, reduced efficiency, equipment failure, unplanned downtime, and increased maintenance costs.

Cortec® VpCI® Solutions for Process Equipment

Cortec® VpCI® technology helps protect ferrous and non-ferrous metals by forming a molecular corrosion-inhibiting layer on accessible metal surfaces. Products can provide protection through direct contact, the vapor phase, or both.

Vapor phase Corrosion Inhibitors migrate through enclosed spaces and reach internal cavities, voids, recessed surfaces, and areas above the fluid level. This makes VpCI® technology useful for complex industrial systems where conventional coatings or contact-only inhibitors may not reach every surface.

Depending on the application, Cortec® products may be added to operating fluids, circulated through a system, fogged into enclosed equipment, applied directly to exposed surfaces, installed inside an enclosure, or incorporated into protective packaging.

Corrosion Protection During Plant Operation

Operating process systems may require corrosion protection for water, oil, fuel, steam, condensate, cooling fluid, or other process streams. Cortec® offers liquid and powder additives for selected operating systems where corrosion protection must work within the existing fluid.

Product selection depends on metallurgy, fluid chemistry, concentration, temperature, pressure, flow, contaminants, process requirements, and discharge limitations. Compatibility with seals, coatings, filters, catalysts, and finished products must also be evaluated.

Corrosion inhibitors used in operating systems should be selected and monitored by qualified plant, water-treatment, process, and corrosion professionals.

Plant Shutdown and Turnaround Protection

Planned shutdowns and maintenance turnarounds create different corrosion risks than normal operation. When equipment is drained, opened, cleaned, or exposed to atmospheric conditions, residual moisture and contamination can attack newly exposed metal surfaces.

Boilers, heat exchangers, piping, tanks, pumps, compressors, turbines, electrical systems, and spare equipment may remain idle for weeks or months. Changes in temperature can also cause condensation inside equipment that appears dry.

Cortec® products can be incorporated into shutdown procedures to protect equipment throughout inspection, maintenance, repair, and recommissioning. Treatment methods may include wet layup, dry layup, internal fogging, temporary coatings, corrosion-inhibiting lubricants, VpCI® emitters, and protective packaging.

Short-Term and Long-Term Equipment Layup

Equipment layup may be required during seasonal shutdown, reduced production, construction delays, facility mothballing, or long-term storage. The preservation method should reflect how long the equipment will remain idle and how quickly it must return to service.

Wet layup generally keeps a compatible system filled with treated fluid. Dry layup usually involves draining the system and establishing a protective environment around the internal metal surfaces. Cortec® VpCI® products can support both approaches in appropriate applications.

The selected method should account for equipment geometry, metallurgy, residual process materials, internal volume, drainage, closure, temperature, humidity, monitoring, and recommissioning procedures.

Hydrostatic Testing and Post-Test Preservation

Hydrostatic testing introduces water into pipelines, tanks, valves, heat exchangers, pressure vessels, and fabricated equipment. Even after draining, water may remain in low points, narrow passages, dead legs, valve bodies, and internal cavities.

Cortec® VpCI®-649 Series products provide options for corrosion protection during compatible hydrostatic testing and post-test storage. Selected formulations protect ferrous and non-ferrous metals through contact and vapor-phase action.

The correct product and concentration depend on water quality, chlorides, hardness, metallurgy, test duration, temperature, discharge requirements, final equipment service, and the expected delay before commissioning.

Heat Exchanger and Condenser Preservation

Heat exchangers and condensers contain extensive internal surface area, narrow passages, dissimilar metals, and locations where residual water may remain after draining. Tube bundles may also require protection during fabrication, shipment, retubing, storage, or shutdown.

Compatible preservation methods may include treated hydrotest water, internal fogging, VpCI® powders, protective end closures, temporary external coatings, and VpCI® packaging. Product selection should account for tube and shell metallurgy, operating fluid, residual contamination, and recommissioning requirements.

Tanks and Process Vessel Protection

Storage tanks, reactors, pressure vessels, columns, and process containers may experience internal corrosion when they are emptied, cleaned, hydrotested, or placed into standby. Moisture and oxygen can remain inside even when the equipment appears dry.

Cortec® VpCI® products can be fogged, circulated, sprayed, or otherwise introduced into compatible enclosed spaces to establish a corrosion-inhibiting environment. Exterior surfaces may be protected with temporary or permanent coatings selected for the expected exposure.

Food-contact, potable-water, chemical-service, and high-purity vessels require product-specific compatibility and regulatory review.

Pumps, Compressors, and Rotating Equipment

Pumps, compressors, turbines, gearboxes, and other rotating equipment contain internal passages, precision surfaces, bearings, seals, and lubrication systems. These components may corrode when equipment is stored, shipped, installed but not commissioned, or taken offline for maintenance.

Cortec® products for rotating equipment may include internal fogging fluids, oil-compatible corrosion inhibitor additives, protective lubricants, temporary coatings, VpCI® emitters, and corrosion-inhibiting packaging.

Lubricant compatibility, seals, bearings, filters, operating temperatures, and manufacturer requirements must be evaluated before treatment.

Boiler, Steam, and Condensate Systems

Boiler systems and condensate lines can develop corrosion during operation and shutdown. Water, dissolved oxygen, heat, changing pH, and residual moisture may attack tubes, drums, piping, and other internal surfaces.

Cortec® offers products for compatible operating-water treatment, wet boiler layup, dry boiler layup, startup protection, and condensate-system preservation. Treatment selection depends on boiler design, pressure, metallurgy, water chemistry, steam use, shutdown duration, and return-to-service requirements.

Cooling Water and Closed-Loop Systems

Cooling systems may experience corrosion, scale, mineral deposits, biological contamination, and damage associated with changing water chemistry. Closed loops may also corrode during extended shutdown or when air enters the system.

Cortec® water-treatment products provide corrosion-control options for compatible closed-loop, cooling-water, and seasonal layup applications. Products should be selected according to system metallurgy, temperature, fluid composition, makeup water, contaminants, and operating conditions.

Electrical and Electronic Equipment Protection

Process plants often contain electrical equipment exposed to humidity, condensation, corrosive vapors, dust, sulfur compounds, and temperature changes. Control panels, junction boxes, switchgear, motors, instrumentation, and automation equipment can corrode during operation or shutdown.

Cortec® VpCI® emitters can protect metal components inside compatible enclosed, non-ventilated cabinets and control boxes. ElectriCorr® cleaners and protective products are available for selected electrical and electronic applications requiring direct cleaning or surface protection.

Corrosion Under Insulation

Water entering damaged or aging insulation systems can become trapped against piping, vessels, and equipment. Elevated temperatures, chlorides, and repeated wet-dry cycles may accelerate corrosion beneath insulation where damage is difficult to detect.

Corrosion under insulation requires proper inspection, water exclusion, insulation-system maintenance, coating selection, and corrosion monitoring. Application-specific Cortec® products may supplement these measures but should not replace a complete facility CUI management program.

Valves, Flanges, and Fastener Protection

Valve components, machined flange faces, bolts, threads, stems, and other exposed metal surfaces may corrode during storage, construction, maintenance, and plant shutdown. Damage to a flange face can delay installation and may require cleaning or resurfacing.

Cortec® removable coatings, lubricants, VpCI® films, papers, and protective covers can help preserve these components. Product selection should consider the surface finish, gasket materials, process service, temperature, removal method, and commissioning requirements.

Industrial Cleaning and Rust Removal

Oils, grease, scale, rust, process residues, and other contamination may need to be removed before inspection, repair, coating, or preservation. Cortec® offers cleaners, degreasers, rust removers, and scale-removal products for compatible metals and industrial systems.

The correct cleaning process depends on the contaminant, substrate, equipment geometry, temperature, application method, wastewater limits, and next maintenance step. Surface neutralization or rinsing may be required for certain products.

Temporary Coatings and Rust Preventatives

Temporary coatings can protect process equipment, machinery, structural components, flange faces, stored parts, and exposed metal during construction, shutdown, transportation, and layup.

Cortec® offers water-based, solvent-based, removable, wax-like, oily, and dry-film rust preventatives for different indoor and outdoor conditions. Products such as VpCI®-368 provide removable protection in aggressive environments, while VpCI®-391 provides a water-based, dry, non-tacky temporary coating.

Critical Spare Parts Preservation

Process plants depend on replacement pumps, valves, motors, bearings, seals, instrumentation, and other critical spares. These components may remain in storage for years before being needed, making corrosion control essential to equipment readiness.

A preservation program may include cleaning, direct-applied rust preventatives, internal fogging, VpCI® films, bags, papers, emitters, pouches, desiccants, protective caps, and periodic inspection.

Stored parts should be labeled with the preservation date, product used, inspection schedule, and any removal or recommissioning requirements.

VpCI® Packaging for Process Equipment and Parts

Cortec® corrosion-inhibiting packaging can protect parts and equipment during manufacturing, warehousing, domestic transportation, and overseas shipping. Available formats include VpCI® films, bags, papers, fabrics, foams, emitters, and pouches.

Packaging products can protect small fasteners and electronic components as well as large pumps, motors, valves, machinery, and palletized equipment. The package should be sufficiently enclosed to retain the VpCI® vapors and designed for the expected storage and transportation conditions.
