SSPC-SP12/NACE No. 5: High-Pressure Waterjetting for Surface Preparation

SSPC-SP12/NACE No. 5 is a joint standard developed by the Society for Protective Coatings (SSPC) and the National Association of Corrosion Engineers (NACE) that describes the use of high-pressure waterjetting to achieve a defined degree of cleaning of surfaces prior to the application of a protective coating or lining system. This standard includes the end condition of the surface plus materials and procedures necessary to verify the end condition.

SSPC-SP12/NACE No. 5 is a widely accepted standard in the coatings industry and is used by many companies to ensure that their surfaces are properly prepared for coating. The standard is limited in scope to the use of water only without the addition of solid particles in the stream.

Benefits of SSPC-SP12/NACE No. 5 for Steel Surface Preparation

• Waterjetting can remove a wider range of contaminants than traditional abrasive blasting, including rust, scale, grease, oil, and paint.
• Waterjetting does not create dust or debris, which can be hazardous to workers and the environment.
• Waterjetting is a more efficient and cost-effective way to prepare steel surfaces for coating than traditional abrasive blasting.

If you are looking for a way to ensure that your steel surfaces are properly prepared for coating, SSPC-SP12/NACE No. 5 is a great option. This standard provides a clear and concise set of requirements that can be used to ensure that your surfaces are clean and free of contaminants.

Key Requirements of SSPC-SP12/NACE No. 5

• The waterjetting equipment must be capable of producing a high-pressure, high-velocity water stream.
• The waterjetting nozzle must be properly sized and positioned to ensure that the water stream is focused on the surface to be cleaned.
• The waterjetting pressure and velocity must be sufficient to remove all contaminants from the surface.
• The waterjetting process must be monitored to ensure that the surface is being cleaned properly.
• The cleaned surface must be inspected to verify that it meets the requirements of the standard.

SSPC-SP12/NACE No. 5 is a valuable resource for anyone who is responsible for preparing steel surfaces for coating. This standard provides a clear and concise set of requirements that can be used to ensure that your surfaces are clean and free of contaminants.
