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-VHT FEATURES
REINFORCEKiT 4D-VHT is recommended to repair and reinforce pipe
operating at temperature between +100C (+212F) to +250C (+482F)
subject to external and internal corrosion, dents or mechanical
damages. The system restores the pipe integrity and prevents from
further deterioration. This composite sleeve is made of 280 g/m
Fiber Glass tape and ceramic reinforced epoxy resin. This specific
resin composition provides good anti-abrasion and chemical
features.

APPLICATION NOTES
KIT COMPOSITION The REINFORCEKiT 4D-VHT is made of 50 m long
Fiber Glass tape and 17 kg of R3XHT 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 R31080 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.
