Réparations de points chauds

Hot spot repairs are localized maintenance activities on small, high-risk areas of steel structures or pipelines where coating or metal failure has occurred. They prevent damage from spreading and extend the life of the asset until larger maintenance can be scheduled.

Where are hot spot repairs needed?

Hot spot repairs are 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 – bridges, cranes, boilers, turbines.

For you as an operator, hot spot repairs provide fast, targeted intervention without requiring full shutdowns or complete recoating.

Extra explanation

Causes of hot spots:

• Localized corrosion (pitting, crevice, or CUI).
• Mechanical damage (impact, abrasion).
• Coating failure at welds or joints.

Advantages:

• Quick execution.
• Reduces risk of leaks or structural failure.
• Cost-effective compared to large-scale recoating.

Standards often require hot spot repairs to meet the same Sa 2½ surface prep as larger jobs.
