R4D - EC

Composite repair for damaged pipe

REINFORCEKiT® 4D-EC (R4D-EC) is an advanced permanent composite repair system for pipes suffering from external corrosion, dents, weld defects or mechanical damages.

The original 3X ENGINEERING concept is an association of Kevlar® tape and specific bi-component epoxy resin called R3X1060, which allows a safe and easy installation unlike any other products on the 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 & DNV-OS-F101 standards, this patented product is designed to restore pipe original integrity. There are no limits in terms of pressure, and it could be used without shutdown from -20°C to +55°C.

We have developed our own software called Reinforcekit Engineering Analysis (R.E.A) to design the composite repair and define the material requirements in accordance with existing international standards.
