Step 3 Use clean, dry cloth to remove sanding dust from all sanded surfaces. NOTE: If surfaces are contaminated with grease or piping dope, use clean solvent to thoroughly clean bonding surfaces, then resand surfaces. MIX AND APPLY ADHESIVE NOTE: Adhesive shelf life is six months. Check pro- duction date on box. Step 1 Confirm bonding surfaces of turbine enclosure and FRP coupling are dry, clean, and sanded. Step 2 Thoroughly mix two part adhesive in accordance with detailed mixing instructions contained in adhesive kit. Step 3 Apply adhesive with supplied putty knife to prepared surfaces on both fiberglass turbine enclosure and FRP fitting flanges.

'Male section to be inserted from the inside ofthe turbine enclosure ATTACH FRP COUPLING Step 1 Insert male threaded coupling section from inside of turbine enclosure. Step 2 Screw female threaded section from outside of turbine enclosure. Step 3 Tighten down both sections by hand tightening until adhesive is squeezed out from flange faces. NOTE: Hand tighten only. Step 4 Use flat stick or putty knife to fill in all gaps around coupling flange and turbine enclosure wall. CURING Step 1 Allow a minimum of four hours for adhesive to harden. NOTE: Mating parts must not be moved before adhe- sive is fully cured. Step 2 For outside ambient temperatures below 60°F, apply supplemental heat to initiate adhesive curing process. NOTE: READ Adhesive Application Guidelines in Section D4. Step 3 Testcoupling. NOTE: See Section D8, Hydrostatic Water Test for details. Step 4 After successful test, install secondary piping into FRP coupling. DISPOSE OF UNUSED CATALYST, ADHESIVE Step 1 Mix unused tubes of catalyst and any unused cata- lyst with adhesive to form a solid for safe disposal. Step 2 Dispose of resulting solid as a nonhazardous waste in accordance with federal, state and local regulations. E2. SECONDARY PIPING CONNECTION Two most commonly used methods to secondarily contain piping: ♦ Double -Wall fiberglass pipe (see figure 37). ♦ HDPE secondary containment system (see figure 38). (vote: Fiberglass pipe manufactured by Smith Fiberglass and Ameron are dimensionally compatible with the Con- tainment Solutions supplied FRP Coupling. Typical methods to attach secondary piping are shown in the following drawings: FIGURE 37 Field Instal ked FRP Cc+rp riq Uwu VVtir FRP Eoube tkall F;pc Female Section Turtairie Enclosure Interior Fiberglass Male Section Secondary Ppe Fiberglass Prrnarrr Pipe Adhesii Fill I Sand inner surface of cnuralrsa orrd ouler surface of fiterQbuc..
