Syntho-Glass®XT system is a unique pre-impregnated, bi-directional composite used to repair and reinforce both internal and external corrosion on pipes or structures. This factory-saturated product ensures proper fiber-to-resin content ratios which are crucial to reliable performance. The Syntho-Glass XT system provides an engineered solution to your pipe repair needs which requires Engineering Intervention from CS-NRI and must be installed by a trained and qualified installation technician in order to be considered an engineered solution.
SynthoGlass XT was developed and tested in accordance with ASME PCC-2 requirements to be considered an engineered repair when installed by a trained and qualified installer, its installation technique is identical to that of SynthoGlass except XT carries stronger mechanical properties and a longer working time which is why it is recommend for applications on larger diameter pipes.

Design
- Syntho-Glass XT was designed to conform to ASME PCC-2, ASME B31, ISO TS24817, DOT, API, and CSA Z662 standards for nonmetallic reinforcing solutions. Consult NRI Engineering for specified use.
Surface Preparation
- Surface preparation and profiling shall promote continuous intimate contact between the FRP system and pipe by providing a clean, smooth, and circumferential surface. Surface preparation shall be in accordance with SSPC-SP1 “Solvent Cleaning” and SSPC-SP11 “Power Tool Cleaning” with a 1-3 mil surface roughness (25-75 microns) minimum. If existing coating is
present, roughen to degloss. NRI’s composite repair systems are bond-critical and require a strong adhesive bond between the clean pipe and the composite system.
Installation
- Installation of the Syntho-Glass XT System shall be performed by NRI qualified applicators only to be considered an engineered solution. Surface preparation, mixing of epoxy, and installation of the system are to be in accordance with NRI’s Syntho-Glass XT Installation Guide, latest revision. Quality control inspection during and after installation of the Syntho-Glass XT system shall be performed per NRI’s Installation Validation Procedure: Quality Control Records, latest revision.
