REINFORCEKiT®4D SUBSEA (R4D-S) is a wet lay-up system, wrapped helicoidally around the pipe in order to bring the mechanical resistance to the damaged pipe section. The number of layers, determined by calculation, is linked not only to the pipe pressure, temperature, diameter and thickness but also to the pit depth and length, the steel grade and the pipe location. The repair design and material requirements are provided by 3X software REA after information compilation according to ASME B31G, ISO 24.817, CSA Z662 and ASME PCC-2 codes and standards.
REINFORCEKiT®4D SUBSEA is recommended to repair and reinforce pipelines operating at temperature between +5°C (+41°F) up to +65°C (+149°F) subject to external/internal corrosion, leaks (if completely stopped prior to composite application), dents and mechanical damages for underwater environment. The system restores the pipe integrity and prevents from further deterioration. This composite sleeve is made of 400 g/m² Kevlar® tape and ceramic reinforced subsea curing epoxy resin. The specific resin composition provides excellent anti-abrasion and chemical features. The composite is tolerant to wet conditions.
