Choosing industrial ductwork shouldn’t come down to the price per foot of straight pipe. While spiral pipe may offer a lower initial material cost, US Duct and US Tubing are designed as complete systems that provide advantages in installation speed, durability, adjustability, sealing, and long-term value. This article compares spiral pipe with US Duct and US Tubing, highlighting key differences in construction, connections, leakage performance, field installation, and lifecycle costs. US Duct offers a strong, modular, adjustable solution for dust collection, most fume applications, and industrial air movement, while US Tubing provides a guaranteed leak-free connection for applications where air or fluid cannot escape. With clamp-together installation that can reduce installation time by approximately 70%, plus components that can be disassembled, modified, and reused, US Duct and US Tubing can deliver value well beyond the initial material price. The right choice ultimately depends on the system’s specific requirements for strength, sealing, installation speed, adjustability, and long-term flexibility.
Segmented Elbows
Details
Segmented, or gored, Elbows deliver smooth, sweeping directional changes for larger-diameter dust collection and ventilation lines. Built with a 1.5D centerline radius (the radius equals 1.5 times the duct diameter), they create a gradual turn that keeps airflow moving efficiently and reduces abrasion from high-velocity chips and dust, making them ideal for main lines and larger drops.
Route your system, change direction, or reconfigure a run in seconds, and just as easily take it apart for cleaning or relocation.
