Flanged Ducting

Flanged Duct Pipe and Large-Diameter Systems

Our flanged systems are built for durability and ease of assembly. Each section features a floating 3/8″ Van Stone lip, allowing the angle flange to rotate freely for quick bolt-hole alignment. Available in galvanized, aluminum, and stainless steel, these systems can be customized with 3/16″ thick flat flanges or no-fitting ends to match existing facility patterns.

Whether you are installing a new centralized system or connecting to a Flange Adapter for snap-together pipe, we provide the industrial-grade components your facility requires.

Skip the wait. Speak to a human. Direct Line: 317-910-1497
