Roben, Mfg, Inc. is a leading provider of custom seismic-resistant storage tank fabrication services, specializing in the design, engineering, and manufacturing of earthquake-resilient storage solutions for critical applications. With our expertise, advanced engineering capabilities, and commitment to safety and structural integrity, we deliver custom seismic-resistant storage tanks that meet the unique requirements of our clients and maintain operational reliability even under severe seismic events.
1. How do you determine the seismic design criteria for a storage tank?
We use site-specific hazard analysis, regional seismicity, soil data, tank geometry, and CFD simulations to establish robust seismic design criteria.
2. What are the key differences between standard tanks and seismic-resistant tanks?
Seismic-resistant tanks feature enhanced detailing, reinforced components, seismic isolation, flexible connections, and foundation systems that accommodate seismic forces.
3. How do you address sloshing effects in seismic-resistant liquid storage tanks?
We apply CFD modeling, increase freeboard, add anti-sloshing devices, and reinforce roof structures to mitigate sloshing-induced forces.
4. What types of foundation systems do you recommend for seismic-resistant tanks?
We recommend reinforced ring walls, pile foundations, isolation pads, anchor bolts, and engineered fills depending on site conditions.
5. What are the typical lead times for custom seismic-resistant storage tank fabrication?
Lead times range from 16 to 44 weeks depending on complexity. We offer phased timelines: 3–5 weeks (analysis), 4–8 weeks (design), 4–12 weeks (materials), 6–22 weeks (fabrication), and 1–2 weeks (testing).
