Fiberglass Tanks
Time to Read: 1m 44s
Most fiberglass tanks are manufactured using the highest quality corrosion-resistant reinforced plastic (FRP) materials. Products include process vessels, chemical storage tanks, foul air ducting, piping and more. Tanks should be designed and fabricated to your specifications in accordance with ASTM or other world industrial standards. This can be done using the highest performance, high temperature epoxy vinyl ester resins. Common applications include acids, alkali, bleaches, brines, chlorides, solvents, oxidizers and more.
Shop manufacturing is possible up to about fourteen feet (~four meters) diameter using either a filament winding or spray-up process. The thermoset resins used in both filament wound and spray-up fabrication commonly include polyesters, vinyl esters and isophthalics. Filament winding consists winding resin-impregnated glass fibers in predetermined patterns. After the laminate layers are wound-on, the tank shell is allowed to cure at room temperature before secondary bonding operations begin. Spray-up is an open molding fabrication method used to make tank bottoms and dished tops and parts that have large surface area. Chopped fiberglass reinforcements and catalyzed resin are deposited onto a mold surface. Rollers or squeegees are used to remove entrapped air and work the resin into the reinforcements. Woven fabric is added to give the laminate greater strength. Fiberglass tanks larger than 14 feet (~4 meters) diameter are generally not economical to ship so they are usually shop fabricated in segments and shipped to your site. Large diameter, field erected fiberglass tanks are made using the same materials and fabrication methods as standard shop-fabricated tanks. The tank shell may be either chop/hoop wound or contact molded. The bottom, dished head and all joints and secondary bonding are contact molded. Since the cost per unit of volume stored usually decreases with larger vessel sizes, it may be that one large diameter, field erected tank will be more economical than multiple smaller, shop fabricated tanks to store the same volume.
