Fiberglass Weir & Baffle Systems
General: All flow control weir shall be produced from fiberglass reinforced isophthalic polyester resins. Weirs may be v-notched, square notched, straight flat edge, or straight beveled edge. V-Notch weirs shall have evenly spaced notches throughout the length of the weir except at the splice joint. Scum baffles, scum baffle brackets, weir washers, and splice plates shall be made of same materials as the weirs above.
Fabrication: Weir plates shall be furnished with oversized holes or slots for mounting. Typical mounting holes are 2-5/8”ø on 2’0” c-c. Other hole sizes or slots at other center to center configurations can be furnished as required. Weir and baffle splice plates are fabricated from sheet molded plates, manufactured as above.
Availability:
Standard weir sizes are:
- ¼” x 9” tall with 2” vee on 4” centers x 11’11-1/2” long
- ¼” x 9-1/2” tall with 2-1/2” vee on 6” c-c x 11’11-1/2” long
- ¼” x 10” tall with 3” vee on 6” centers x 11’11-1/2” long
Standard scum baffles are:
- ¼” x 12" tall x 12`0" long
Standard scum baffle brackets are:
- upper - 4" wide x 6" deep x 10" tall
- lower - 4" wide x 7" deep x 10" tall
Manufacture of Components:
Standard weir plates, scum baffle plates, scum baffle support brackets, weir washers, and splice plates are sheet molded in match metal molds to produce smooth resin rich surfaces free of voids and porosity. Pressure in molds will exceed 10 psig. Molded edges of all parts are sealed in the mold. Holes or other cuts are sealed after cutting. Bevels on standard vee patterns are molded-in bevels.
Non-Standard sizes or configurations:
Glass·Steel, Inc. in addition to its standard line of weirs and baffles can produce weirs and baffles in any size or configuration required. Materials can be molded or pultruded in thickness of ¼”, 3/8”, ½”, 5/8”, ¾”, or 1”. V-Notches can be cut can be cut in for smaller quantities or molded in if quantities justify.
