Composite Repair for Subsea Pipe
REINFORCEKiT®4D SUBSEA (R4D-S) is a long-term composite repair system for pipes suffering from external and internal corrosion, dents and leaks in offshore and subsea environments.
The original Brisma Africa concept is an association of Kevlar® tape, specific bi-component epoxy resin called R3X1050S and primer. The composite is tolerant to wet conditions and can be easily installed by trained divers.
REINFORCEKiT® 4D is a wet lay-up system, wrapped helicoidally around the pipe in order to bring the mechanical resistance to the damaged pipe section.
Designed according to ISO 24.817 and ASME PCC-2 standards, this product will restore subsea pipe original integrity. There is no limit in terms of pipe diameter and pressure, and it could be used without shutdown (except in case of leakage) from +5°C up to +50°C (+41°F / +122°F). In case of leakage the process must be stopped prior to composite application.
We have developed our own software R.E.A (Reinforcekit Engineering Analysis) to design the composite repair and define the material requirements in accordance with international standards.

REINFORCEKiT®4D SUBSEA Application
REINFORCEKiT® 4D SUBSEA application is very specific and technically challenging as applying composite products in a subsea environment needs to be performed with highly qualified staff and specially designed equipment. To this purpose, 3X technicians and engineers are trained and certified to work offshore. For subsea repair requiring divers to perform the composite wrapping, Brisma Africa provides subsea operation supervision and co-ordination of technical repair divers (including saturation divers).
