Crimar Industrial has been devoted to the design, fabrication and installation of large-diameter fiberglass tanks for over three decades. Global companies such as FLSmidth, Glencore, M3 Engineering, Technip, Hatch, Biorem, CODELCO, Freeport-McMoRan, WesTech and SNC-Lavalin regularly partner with us on projects spanning North and South America, Africa, China, Australia, the Philippines and Eastern Europe.
Two ways to build very large tanks
When tanks exceed DN4500 mm in diameter, transportation becomes a challenge. Crimar offers two solutions:
- The tank is fabricated (oblated) in our shop and shipped to site for assembly.
- Alternatively, we fabricate the tank directly at the customer’s site using a field winder.
Shop oblation vs. field winding
Oblating fiberglass tanks — a practice from 1960s North America, popularized in the 1970s — offers a controlled shop environment for higher quality, unaffected by wind, rain or direct sunlight. It reduces on-site labor, cost and schedule risk. Field winding, in turn, lowers shipping costs, requires fewer body joints (for heights within 12 m) and speeds delivery of batches of same-diameter tanks. Field winding requires flat, hard ground and adequate space for the winder.
Standards & materials
Our process adheres to globally recognized fiberglass standards including ASME RTP-1, ASTM D3299, D4097, D2996, D2310 and D5421, and EN 13121, EN 4994 and EN 5480. We select corrosion-resistant resins and reinforcements based on the tank’s operating environment — from high-temperature or fire-retardant epoxy vinyl ester to high-corrosion-resistance polyester — with glass reinforcements (roving, mat, woven roving, surfacing veils) and additives such as antimony trioxide, silica carbide and UV inhibitors to enhance performance and durability.
With deep expertise and an unwavering commitment to quality, Crimar continues to deliver large-diameter FRP tank solutions that exceed client expectations. See our FRP tanks & vessels or request a quote.
