Fiberglass Tanks
Fiberglass tanks are fiberglass containers that are used to store gases, liquids, and sometimes solids. Available in varying sizes, fiberglass tanks hold glass fiber reinforcement that is inserted in cured thermosetting resin. Additives including pigments and dyes are also contained in fiberglass tanks.
The effectiveness of a fiberglass tank in a given situation depends on the mixture of glass fibers, additives, and resin, in addition to the tank's design. Fiberglass tanks are used in the petroleum, automotive, wastewater, and chemical industries. Many food plants and chemical plants also make use of fiberglass tanks.
Centrifugal molding is the method of fiberglass fabrication used to form fiberglass tanks. In centrifugal molding, the gel coat is applied to the sides of a spinning cylindrical mold. Layer by layer, catalyzed resins saturated with short fibers are sprayed into the mold until the desired thickness is reached. The end products, the tanks, are then demolded and trimmed.
