Erosion

Erosion is the gradual loss of material from a solid surface caused by mechanical action such as wind, water, slurry, or abrasive particles. Unlike corrosion (chemical attack), erosion is a physical wear process, but the two often act together (erosion-corrosion).

Where does erosion occur?

Erosion damage is common in:

• Oil & Gas – offshore risers, flare booms, topside piping.
• Petrochemical & Chemical plants – process vessels, reactors, insulated pipelines.
• Marine & Offshore wind – deck areas, turbine towers, hull details.
• Infrastructure & Power – hydro turbines, cooling systems, bridges near water.

For you as an asset owner, erosion reduces wall thickness, efficiency, and safety, leading to higher maintenance costs.

Extra explanation

Causes:

• High-velocity fluids carrying sand, silt or debris.
• Cavitation bubbles collapsing near metal surfaces.
• Wind-driven particles (e.g., offshore sand storms).

Consequences:

• Reduced pipeline and vessel integrity.
• Faster coating breakdown when combined with corrosion.
• Unexpected shutdowns due to leaks or ruptures.

Erosion-corrosion is especially severe offshore, where both seawater and abrasive particles attack steel surfaces simultaneously.

Pinovo and erosion management

Pinovo helps manage erosion issues by:

• Removing degraded coatings and rust caused by erosion-corrosion.
• Preparing eroded steel surfaces for recoating or repair.
• Operating dust-free in ATEX zones, even in high-risk offshore areas.
• Supporting longer-term protection when combined with coatings or wraps.

Pinovo does not stop erosion itself, but ensures surfaces are clean and ready for protective systems that resist further erosion.
