The application of a CFRP lining system to a pipeline is a bond critical application, so the surface of the pipeline must be prepared sufficiently to ensure proper adhesion. Concrete surfaces are profiled using abrasive or water blasting to a minimum International Concrete Repair Institute (ICRI) concrete surface preparation CSP 3, as shown in Figure 1.3, whereas a metallic surface will be prepared using abrasive blasting to a near white metal surface profile. Surface contaminants (laitance, carbonated and weak concrete, cracked and spalled concrete) are removed and the substrate is repaired as necessary. The work requires the pipe surface to be thoroughly cleaned, dried, and dehumidified.
