REINFORCEKiT® 4D (R4D) is an advanced permanent composite repair system for pipes suffering from corrosion defects and mechanical damages.
The original 3X ENGINEERING concept is a combination of Kevlar® tape and specific bicomponent epoxy resin, which allows a safe and easy installation unlike any other products on the pipeline wrapping market.
R4D is a wet lay-up system, wrapped helicoidally by external application around the pipe in order to bring the mechanical resistance to the damaged pipe section.
In accordance with ASME B31G, ASME B31.1, ASME B31.3, ASME B31.4, ASME B31.8, ISO/TS 24-817, ASME PCC-2, DNV-RP-F101, DNV-RP-D101 and DNV-OS-F101 standards, this patented product is designed to reinforce a pipe which has lost up to 80% of wall thickness. There are no limits in terms of pressure, and it could be applied at temperatures up to 250°C.
We have developed our own software called Reinforcekit Engineering Analysis (REA) to design the composite repair and define the material requirements in accordance with existing international standards. In case of special requirements, we can provide Finite Element Analysis (FEA) simulation to design the repair or to comply with your own internal standards.
Already installed all over the world, it is THE SOLUTION for a lasting pipe reinforcement method.
