Questions & Answers

QF Pipe is all 5' long, what if I need a 36" L piece?
In this case, you will need the Quick-Fit Adjustable Sleeve to achieve your desired length.

What is the Quick-Fit Adjustable Sleeve?
The Quick-Fit Adjustable Sleeve is an 11" piece used when a 5' length of pipe has been cut smaller.

Do QF Clamps come with the pipe? If not how many do I need to order?
Clamps do not come with pipe. As a rule, you will need one clamp per component ordered.

What are the exact OD and ID of your pipe?
QF Pipe inside and outside dimensions are listed in the table linked under the Info & Guides section above.

How often do I need a hanger?
A Pipe Hanger is needed every 10' as a general rule to support the duct. Please refer to local codes.

How do I connect to the end of an existing non QF system?
We offer a full line of adapters to connect to any existing pipe you might have.

When do I need to use stainless steel?
Stainless steel is used in FDA, chemical and high temperature applications.

Nordfab Ducting General Specifications

Nordfab QF duct is a clamp together design using a rolled edge design with a single lever clamp. The ducting and clamps are constructed from similar materials. All clamps contain a standard gasket made of Nitrile which is suitable for most applications, including oil mist, as long as high temperatures are not an issue. Silicone and ePTFE gasket options are available for higher temperature applications. Nordfab Quick-Fit Ducting is available in 1" increments sized 3" to 24" diameter.

Nordfab’s laser welded seam Quick-Fit^® Ducting System has been used in many different industrial applications, and under various negative static pressures. The typical design range we see in our applications range from -2" wg to - 28" wg; however, there are some systems operating at vacuums of -32" wg to -42" wg under normal operating parameters.

The pipe comes in 5' lengths with a rolled lip on each end, thus providing reinforcement every 5', which presents a sound structural design that should be as strong or stronger than any pipe in its class according to SMACNA guidelines and regulations.

All fit together ducting systems allow for some degree of leakage where they are joined. QF^® Ducting is no exception and is not sold as an airtight system. In comparison to other ducting typically used in fit-together systems, Nordfab’s QF duct pipe has fully welded, leak-tight laser or plasma welded seams. Spiral and other ducting with lockform seams are not fully welded at the pipe seams and can be expected to have higher leakage rates than QF duct.
