In critical facilities such as data centers, uptime is everything. Cooling systems must stay online through every possible challenge—from daily vibration to unexpected seismic activity. Hanna Rubber’s Seismic V and U Loops provide engineered flexibility that protects piping systems and ensures continuous operation when the ground (literally) shifts.
Rigid Systems in a Moving Environment
Cooling systems in data centers rely on precision and consistency. However, rigid metal piping doesn’t adapt easily to movement caused by thermal expansion, structural settlement, vibration, or seismic forces. Without built-in flexibility, pipes and joints can crack or separate—threatening equipment cooling, uptime, and compliance.
That’s where seismic expansion loops come in.
Engineered Flexibility: Seismic V and U Loops for Cooling Systems
Hanna Rubber’s Seismic Expansion Loops are custom-fabricated assemblies that introduce calculated flexibility into thermal piping systems. These loops are designed to absorb motion in multiple directions, preventing damage to welds, joints, and connected components.
Every loop is precision-built for its specific installation, taking into account:
- Pipe diameter and material type
- Flow rate and fluid characteristics
- Building layout and seismic rating
- Environmental factors like temperature, insulation, and exposure
Whether installed indoors or outdoors, each loop is built to perform reliably under dynamic conditions.
Key Advantages of Seismic V and U Loops for Data Centers
✅ Absorbs seismic, thermal, and structural movement
✅ Protects welds, flanges, and fittings from fatigue
✅ Maintains continuous cooling and system performance
✅ Reduces long-term maintenance and repair costs
✅ Extends piping life and overall system reliability
✅ Meets or exceeds seismic and mechanical system codes

FAQs: Seismic Loops in Data Center Cooling Systems
Q1: Are seismic loops required in data centers?
In seismic regions, many building and mechanical codes (such as the IBC) require movement-absorbing components to protect piping systems. Seismic loops help you achieve compliance while ensuring operational safety.
Q2: Can they be installed in existing systems?
Yes. Seismic V and U loops are well-suited for retrofit projects and can be integrated into existing lines with minimal disruption.
Q3: What’s the difference between a V-loop and a U-loop?
Both designs manage movement, but V-loops are ideal where space is limited, while U-loops handle greater displacement. The optimal design depends on your system layout and movement requirements.
Q4: How long does fabrication take?
Lead times vary by design complexity, but Hanna Rubber’s fabrication team can deliver custom seismic loops quickly for time-sensitive projects.
