Pulp and paper mills need corrosion protection in all areas, including processing, production, finishing, and containment. Lack of corrosion protection can lead to an unsafe work environment, contaminated paper, damaged machinery, and regulatory violations.

Types of corrosion impacting the pulp and paper industry

When the metals in the pulp and papers mills are exposed to black liquor and other corrosive substances, the metals are degraded and the metallic components return to their original state. Corrosive gases formed as byproducts of manufacturing or found in the environment add to the problem. Corrosion can impact the metal’s mechanical strength, permeability to liquids and gasses, and appearance.

Multiples types of corrosion can be found in pulp and paper mills, including stress cracking, uniform corrosion, and crevice corrosion and pitting.

• Stress cracking is caused by a combination of vulnerable materials, mechanical stresses and a corrosive environment. These cracks can spread and lead to catastrophic failure.
• Uniform corrosion can be caused by the presence of alkaline solutions and molten salts, where the passive layer that protects the metal breaks down across the entire surface.
• Crevice corrosion and pitting are similar to uniform corrosion, but limited to smaller areas.

Corrosion prevention starts with an analysis of your pulp and paper mills

FSN’s certified industrial coating professionals and certified contractors can provide site-specific evaluations. To determine the proper coatings for your applications, an analysis of the facility, including types of metal, chemicals and wood, will be conducted.

Our industrial coating specialists provide a wide range of services, including:

• Inspections
• Evaluations
• Corrosion Control
• Fireproofing
• Industrial Coatings
• Epoxy Flooring
• Asbestos and Lead Abatement

We make sure surfaces are properly prepared, then apply the most appropriate coating for each surface or application. For floors, epoxy coatings are low maintenance and resistant to water, chemicals, bacteria and germs, heat, impact and abrasion.
