Pipe Coating System
Advanced 100% Urethane Lining Application by Global EcoTechnologies
Endura-Flex® Reaction Bonded Urethane ("RBU") is a product of the Ecosystem® patented gas injection process resulting in verifiably improved performance properties which have been shown to have superior barrier performance characteristics when compared to polymer films provided from other methods.
RBU is fluid applied, rapid setting, solvent-less polyurethane coating (based upon the industry recognized Endura-Flex® 1988 chemistry) for its superior hydrolytic stability and tough yet flexible protective barrier film properties which can be used on the exterior or interior surfaces of steel or concrete pipe.
RBU is not a newly formulated product nor is the product’s technology new, but the result of a combination of two tried and proven technologies coupled with specific procedural modifications resulting in overall enhanced product properties available through the GET licensees.
FOR EXTERNAL, BURIED & IMMERSED APPLICATIONS
Endura-Flex RBU is designed for long term protection of buried or immersed steel pipe. While RBU may be adjusted for applied films direct-to-steel at traditional pipe mill thin film thicknesses for "general use", it is also versatile enough for application at much thicker films when service requirements are more demanding as might be found in rough terrain, marshy areas, sub-sea installations, freeze-thaw exposures, tidal zones and slip bore applications.
ADHESION OVER FUSION-BONDED EPOXIES
EF-RBU also shows excellent adhesion to fusion bonded epoxy offering economical "extra thickness" for those systems when in aggressive back fill or slip bore operations. RBU application versatility allows for application either in plant or in situ with the respective economies available from each method. Quality conscious weld joint coating and field repair methods are available for continuous "same system" use from beginning to end of project.
WASTEWATER, SALT-WATER INTERNAL LINING
Finally, RBU can also be used as an effective corrosion barrier on the interior of pipe as a liner for wastewater water or salt water applications.
