REINFORCEKiT® 4D (R4D) 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 and ASME PCC-2 codes and standards.

REINFORCEKiT® 4D is recommended to repair and reinforce pipelines operating at temperature between -50°C (-58°F) up to +150°C (+302°F) subject to external/internal corrosion, leaks (dedicated procedure for live repair), dents and mechanical damages. The system restores the pipe integrity and prevents from further deterioration. This composite sleeve is made of 400 g/m² Kevlar® tape and highly-reinforced ceramic epoxy resin.
