| Fiberglass Reinforced Plastic Flumes
Composites USA flumes are one piece molded units designed for metering liquids in open channels. The unbroken flow lines present no obstructions which would cause a build up of debris. The unbroken lines also create low head loss characteristics which make the flume ideal for measurements under gravity head requirements.
Each flume design is rigorously checked by our composites structural engineers to verify loadings and anticipated flat plate deflections, if any. All reinforcement glass is precision hand cut (ie., no chopper gun allowed) and laid on the mold for gradual built up to the final required thickness with the specified resin. In this way, the color (if requested) is molded in, part thickness and uniformity is carefully controlled, and problems with typical trouble spots, such as inside corners, are avoided.
With a Composites USA flume, you get quality to audited MIL-I-45208 standards, and design to U.S. Bureau of Commerce Voluntary Guideline PS-15-69, ASTM and ASME Guidelines, as applicable. All resins used are corrosion resistant isophthalic polyester as standard. Premium grade vinyl ester, epoxy or furan, as well as flame and smoke resistant grades are also available as options.
