Pulp and Paper

Corrosion, erosion and abrasion can play a major role in affecting paper plants. When left untreated, it can be common to experience downtime, or even a total shutdown – never a welcome experience – always bringing huge financial costs.

At Corrocoat, we provide the paper industry with the exact coatings to both protect new equipment and refurbish badly-damaged machinery.

Due to the quality of our products, we’ve become renowned for ensuring the job is done properly the first time of and that it stays that way for years to come.

Pulp and Paper Case Studies

US100: Composite External Tank Repair

A process vessel experienced a brick and mortar lining failure resulting in the process environment consuming the carbon steel shell 90’ above grade. A full repair would have required more than a week of unscheduled downtime, so an RFQ was sent out to contractors for an external patch that wouldn’t further degrade the internal liner. Other proposals called for welding, risking further liner damage that could cause bricks to enter the process. Click to read more. 

US101:Pulp and Paper Tall Oil Concrete Coating

A concrete bund area at the Tall Oil plant had deteriorated over time due to exposure to Sodium Hydroxide (NAOH), Black Liquor and occasional exposure to Sulfuric Acid (H2SO4). This led to the containment not draining correctly and the low areas of the surface allowing for standing puddles.

US103: Caustic Saturated Concrete Repair

A tile lined concrete pit submerged at a pH of 14 required immediate repair and refurbishment. The repaired was required to be completed in the short term to prevent further damage and needed to be completed over a 36 hour shut down to limit downtime. Adhesion to the substrate was not possible due to the concrete being saturated with caustic, further complicating the repair process. Click to read more. 

US117: Abrasion Damage

A pair of stainless steel fibre sorters were suffering heavy wear and abrasion damage to the inner stainless steel surfaces of the unit, the plant
operator approached Corrocoat to suggest a solution. Corrocoat was informed that one unit had a previous ceramic tile repair that had failed
and needed replacing.
