Pipe and Duct Riser Supports
ISAT Pipe and Duct Riser Supports Engineering Services: Pipe and duct riser supports represent intricate systems that are exposed to remarkably complex loading patterns. This complexity is particularly pronounced in tall structures, where riser supports must withstand substantial thermal expansion and contraction. Moreover, these supports must also accommodate interstory drift, a term referring to the extent of building movement during seismic events. Consequently, the design and implementation of these supports require a high degree of precision and expertise, particularly when dealing with high-rise buildings.
Pipe risers can be highly subject to failures, exposing overlooked and dangerous loads on buildings. In some cases, risers can even change the stiffness of the building or short-circuit the building’s structural seismic protections or dampeners.

Pipe and Duct Riser Supports
From supplemental steel design for duct risers to engineering positive attachment clamps for pipe risers, ISAT provides 1-stop solutions including:
- Engineering, design, and fabrication
- Vibration isolation
- Piping system thermal expansion and contraction
- Inter-story drift
- IBC/ASCE code compliance
- Field support, installation, and training
In addition to large expansion and contraction, the risers are subject to the horizontal loads imparted by building “drift” (the term used to define how much the building will move during a seismic event). If the systems and their related supports are not designed with adequate flexibility to accommodate the anticipated drift, the risers are often heavily damaged during seismic events causing delays in building availability or worse, wide-scale flooding. ISAT’s team of engineers are trained to avoid these pitfalls while maintaining our lean design approach to the supports and attachments.
