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-EC FEATURES

REINFORCEKiT 4D-EC is recommended to repair and reinforce pipe operating at temperature between -20C (-4F) to +55C (+131F) subject to external corrosion, dents or mechanical damages. The system restores the pipe integrity and prevents from further deterioration. This composite sleeve is made of 400 g/m Kevlar tape and ceramic reinforced epoxy resin. This specific resin composition provides good anti-abrasion and chemical features.

APPLICATION NOTES

KIT COMPOSITION The REINFORCEKiT 4D-EC is made of 50 m long Kevlar tape and 5 kg of R3X1060 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 a combination of solvent washing and MBX or abrasive blasting. After surface preparation, roughness should achieve a minimum of 70m and match with SA 2 or ST3 standards. Then the surface must be cleaned and rinsed using an adequate solvent which evaporates leaving no film residue.

APPLICATION Check atmospheric conditions before job start (TDew point +3C< TSupport; 85%RH). If the pipe presents some pitted areas, specific filler must be used to fill pits and reshape the pipe. Apply a uniform layer of R3X1060 resin on the whole surface. The Kevlar tape is then impregnated and wrapped helicoidally over the pipe. Application instructions are provided to technicians during a 3X training course. Apply a protective coating as per company standards and local pipe environment (UV, swamp, etc).

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