PART 1 – FIBERGLASS REINFORCED PLASTIC (FRP) WEIR AND SCUM BAFFLES 1.01 Description of Work The work covered by this section shall include materials for the fiberglass reinforced plastic (FRP) Weir and Scum Baffle Panels, which includes but is not limited to: A. FRP Weir panels. B. FRP Scum Baffle panels. C. FRP Splice plates. D. FRP Scum Baffle supports. E. Stainless steel fasteners and connections. 2.01 Materials A. FRP weir and scum baffle panels and appurtenances shall be fiberglass reinforced plastic molded to produce uniform smooth surfaces. Factory cut edges and drilled holes shall be sealed with resin. Enduro recommends Sherwin Williams Macropoxy 5500LT or Sherplate 600, or Carboline Carboguard 61. B. FRP Weir Panels a. Panel mounting holes shall be oversized to provide for vertical and horizontal alignment of at least +/- 1” (2 inches total) and shall be placed at 24” on center (maximum) for round tanks and 12” on center (maximum) for straight tanks and covered with 5-inch diameter FRP weir washers, or unless otherwise indicated in the plans and specifications. b. Mounting hardware shall be stainless steel concrete anchors or bolt type fasteners. C. FRP Scum Baffle Panels a. FRP Scum Baffle panelsshall be a nominalsize of 1/4” thick x 12” high x 12’-0” standard length (other panel heights available) unless otherwise indicated on the drawings. b. FRP scum baffle panel standard splice plates shall be 1/4” thick x 12” high x 6” long unless otherwise indicated on the drawings. Panel surface mounting holes shall be countersunk to accommodate flathead fasteners. c. Scum baffle support brackets shall be 3/8” thick x 6” deep x 6” high x 6” long FRP angles with adjustable mounting holes to provide for vertical and radial horizontal alignment of at least +/- 3/4" (1.5 inches total) to be installed on 48 inch maximum spacing. d. Mounting hardware shall be stainless steel concrete anchors or bolt type fasteners. D. Hardware a. Shall be 316 stainless-steel for fasteners, anchorage, and other structural hardware provided by the manufacturer. b. Scum baffle support fasteners shall be nut and bolt type assembly with washers and lock washer. c. Mounting anchors shall be expansion (wedge) type or adhesive type (sized as required).
