Step #3 Mix and Apply Adhesive Note: Adhesive shelf life is six months. Check produc- tion date on box. • Confirm bonding surfaces of turbine enclosure and FRP coupling are dry, clean, and sanded. • Thoroughly mix two part adhesive in accordance with detailed mixing instructions contained in adhesive kit. • Apply adhesive with supplied putty knife to prepared surfaces on both fiberglass turbine enclosure and FRP fitting flanges.

Step #4 Attach FRP coupling Insert male threaded coupling section from inside of tur- bine enclosure. • Screw female threaded section from outside of turbine enclosure. • Tighten down both sections by hand tightening until ad- hesive is squeezed out from flange faces. Note: Hand tighten only. • Use flat stick or putty knife to fill in all gaps around coupling flange and turbine enclosure wall. Step #5 Curing • Allow minimum of four hours for adhesive to harden. ❑ Mating parts must not be moved before adhesive is fully cured. • For outside ambient temperatures below 60°F, apply supple- mental heat to initiate adhesive curing process. ❑ See Adhesive Application Guidelines in Section F5. • Test coupling: ❑ See Section F7, Hydrostatic Water Test for details. ❑ After successful test, install secondary piping into FRP coupling. Step 46 Disposal of Unused Catalyst, Adhesive. • Mix unused tubes of catalyst and any unused catalyst or adhesive to form a solid for safe disposal. • Dispose of resulting solid as a nonhazardous waste in accordance with federal, state and local regulations. 26 G4. Secondary Piping Connection Two most commonly used methods to secondarily con- tain piping: • Double -Wall fiberglass pipe. • HDPE secondary containment system. Note: Fiberglass pipe manufactured by Smith Fiberglass and Ameron are dimensionally compatible with the Fluid Containment supplied FRP Coupling. Typical methods to attach secondary piping are shown in the following drawings: Installed FRP Coupling Used With Fiberglass Double -Wall Pipe Turbine Enclosure Interior Female Section Male Section Fiberglas Secondary Pipe Fiberglas t Primary Pipe Adhesive FII O Sand inner surface of coupling and outer surface of Fiberglas pipe.
