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.
Ball Joints
Details
End dragging or kinked flex hose connections on cutter heads and other moving equipment by installing a Ball Joint. The base swivels a full 360 degrees, letting the hose move freely above the machine while airflow stays steady. It's the simple fix for flex hose that keeps binding, sagging, or wearing out where your equipment moves, and it pairs well with swivel joints for even greater range of motion.
Rolled-lip end that connects to Quick Clamp Clamp-Together Duct (CTD) using quick clamps and gaskets, while the hose side connects in minutes with a simple worm clamp (not included). Fast to set up, easy to adjust, and quick to take apart for cleaning or relocation.
