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.
Swivel Joint
Swivel joints allow for movement between flex hose and duct, or between two pieces of hard duct (link to ducting), but along a 360 degree stationary plane.
The joint consists of overlapping duct joined by ball-bearings that provide a reflectively low friction swivel for periodic or constant spinning movement. Swivel joints can connect spiral pipe or flex hose to allow the rotation of a dust or fume hood, making it an ideal solution for CNC router & other machines with traversing heads.
Available in 3"-12" diameters. Larger diameters available upon request.
