Flanged Pipe

Nordfab® Flanged Duct Pipe is for use in dust collections systems when the pipe size must be greater than 24″ diameter or when flanged connections are required.

The rotational industry-standard Angle Flanges on our Flanged Pipes are retained by Van Stone lips on the pipe ends. Pipe length is nominally 5′.

Angle Flange Gaskets available.
Use with our Angle Flange Adapter for quick connections to QF Pipe and fittings.
Available in galvanized steel and 304SS (as shown below) or optional 316SS or carbon steel
Available with QF ends in diameters up to 24", and with other end types including flanges with custom bolt hole patterns
Other material gauges include 18, 16, 14, 12 and 10

Contact Nordfab or your local Nordfab dealer for assistance with optional end types, larger sizes, and material / gauge options.
