Coastal Steelwork and Pipeline Polyurea Protection Reference Design
A coating selection and detailing concept for salt-laden, wet and maintenance-constrained exposure.
Send project requirements
Final design must be re-engineered for cell chemistry, capacity, enclosure layout, local codes and project testing.
Project assumptions
Outdoor carbon-steel pipework and supports near the coast, with welds, flanges, transitions and intermittent standing water.
Primary risks
Salt deposition, wet-dry cycles, UV, crevices, mechanical damage and inaccessible details accelerate underfilm corrosion.
System architecture
Assess exposure and substrate, prepare and repair steel, select primer, apply spray polyurea on broad areas, detail restricted zones and add a compatible topcoat where required.
Design objectives
Create a continuous barrier, preserve maintainable details and establish inspection and repair points.
Customer data required
Steel grade, existing coating, corrosion state, salts, climate, operating temperature, geometry, access, target life and inspection plan.
Application boundary
Final surface preparation, formulation, thickness and test requirements must be agreed for the actual exposure and maintenance regime.
