Prepreg System for Pipe Protection and Reinforcement

Product Sheet

REINFORCEKiT® 1D (R1D) is a water activated prepreg system, wrapped helicoidally around the pipe to restore its original integrity without shutdown.

REINFORCEKiT® 1D repairs and reinforces pipes suffering from corrosion and mechanical damages. This composite product is made of fiber glass and polyurethane resin.

REINFORCEKiT® 1D can also be used as protection for coated pipes.

In case of reinforcement application, the product must be used with specific 3X filler and primer. The repair design and material requirements are provided by 3X software, according to ISO 24.817 & ASME PCC-2.

In case of protection application, only R1D prepreg tape is necessary. 3X recommends to apply a minimum of 2 layers.
