REINFORCEKiT® 4D

Composite repair for damaged pipe

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 an association of Kevlar® tape and specific bi-component epoxy resin, 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 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 without shutdown up to 150°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. In case of special requirements, we can provide Finite Element Analysis (F.E.A) 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.





Uses

  • Reinforce damaged pipe: internal & external corrosion, abrasion.
  • Prevent from further corrosion /deterioration
  • Repair pipe with leakage, dent, weld defect ...
  • Sabotage: make illegal valve unusable

Applications

  • Onshore, Offshore and Subsea
  • All pipe geometries (tee, elbow, oval pipe ...)
  • All pipe diameters (no limitation)
  • Pipe operating from ambient up to high temperature
  • High pipe pressure

Benefits

  • Online repair (no shutdown required except if leakage)
  • No heating or post-curing needed
  • No pressure limitation
  • No overload on corroded pipes
  • Fiber not hazardous for users
