Centek Marine Vernatube Thruster Tunnel
Centek Marine’s Thruster Tunnels achieve superior axial and longitudinal strength through the use of the continuous interweaving helical winding process. The 56° weaving pattern ensures fully interlocked composite fibers, which provides greater durability and longevity than achievable from traditional construction technologies such as pultrusion, hand layup, or centrifugal casting. Vernatube® is a resin-impregnated glass filament wound tubing made exclusively with a fire-retardant resin formulated for high temperature applications. Centek Marine uses the fire-retardant Vernatube to fabricate many of the basic marine exhaust components. Vernatube exceeds values for the class of materials designated as ‘self-extinguishing’ per ASTM-D-635, UL94V-O, and the US Navy/USCG MIL-R-21607 and MIL-R-7575. The smooth, resin-rich I.D. assures minimal restriction to exhaust gases and cooling water flowing through the tubing. Precise control of the outside diameter ensures ease of connecting mating ports with marine exhaust hose. All tubing products may be factory machined to fit exact hull dimensions.
