REINFORCEKiT4D DESCRIPTION

REINFORCEKiT 4D is an advanced permanent composite repair system for pipelines and piping suffering from corrosion defects and mechanical damage. Reinforcekit 4D is engineered to restore pipe original integrity without shutdown. It is a non-metallic technical alternative to metal clamps, welded sleeves and pipe replacement. Thoroughly tested by third-party laboratories REINFORCEKiT is a 3X Engineering patented concept which provides the required strength according to ASME B31G, ISO 24817 and ASME PCC-2 codes and standards.

The original 3X concept is a combination of Kevlar tape and specific epoxy resin. The bi-directional woven high-strength aramid-fiber material provides reinforcement in the hoop and axial directions. The epoxy resin allows binding and transferring loading through the whole composite system.

REINFORCEKiT 4D is a wet lay-up system. It is 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 is provided by 3X software REA after information compilation according to ASME B31G, ISO 24817 and ASME PCC-2 codes and standards.

REINFORCEKiT4D-S FEATURES

REINFORCEKiT 4D-S is recommended to repair and reinforce pipe operating at temperature between +10C (+50F) to 50C (+122F) subject to both external and internal corrosion, dents and leaks (if completely stopped prior to composite application) for underwater environment. This composite sleeve is made of 400 g/m Kevlar tape and ceramic reinforced subsea curing epoxy resin. The specific resin composition provides excellent anti-abrasion and chemical features. The composite is tolerant to wet conditions and can be easily installed by trained divers. The diving friendly Bobiwrap tool was developed to provide alternative subsea wrapping solution in order to limit significant diving team.

APPLICATION NOTES

KIT COMPOSITION The REINFORCEKiT 4D-S is made of 0.5kg of P3X32 primer, 50 m long Kevlar tape and 11.6 kg of R3X1050 epoxy resin.

SURFACE PREPARATION Proper surface preparation is critical to the long term performance of the composite. All rust, mill scale, corrosion products and foreign matter must be removed from the surface by abrasive blasting. After surface preparation, roughness should achieve a minimum of 60m and cleanliness matches with WJ-3 standards. Then the surface must be cleaned.

APPLICATION If the pipe presents some pitted areas, specific subsea filler must be used to fill pits and reshape the pipe. Apply a uniform layer of P3X32 primer on the whole surface. The Kevlar tape is pre-impregnated using BOBIPREG device onshore and is given to divers. Using handles, the tape is then wrapped helicoidally over the pipe. Application instructions are provided to technicians during a 3X subsea training course.

SAFETY Each applicator should read and understand the Material Safety Datasheet before use 3X products.
