To whom it may concern
Reference: Structural integrity of “QF” Piping System
The Nordfab Laser “Quick-Fit” Piping 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 we have some systems
operating at vacuums of -32” wg to -42” wg under normal operating parameters.
Please take into account that our 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 stronger than any pipe in its class according to
SMACNA guidelines and regulations.
Sincerely,
Tom Ballus
President
All fi t together ducting systems allow for some degree of leakage. “Q-F” ducting is no exception and is not sold
as an airtight system. In addition to our standard Nitrile gasket, NORDFAB offers special clamp gasket material
for high heat, food applications, etc. However, the “Q-F” system is sold as a quick way of installing and modifying
duct-work while at the same time retaining the usability of each component. In short, “Q-F” is meant to be able to
be taken apart, re-assembled, stored or moved. Completely eliminating the possibility for leakage jeopardizes the
inherent benefi ts of the duct.
While NORDFAB is currently unaware of any method of evaluating dust collection piping alone, the following data
is presented using the criteria for all duct, including HVAC. This data is presented only for the purpose of indicating
acceptability of the “Q-F” in dust/fume removal in a negative pressure situation and should not be confused with the
ducting that uses tape or gaskets as sealant in the positive conveyance of air.

MANUFACTURING PROFILE:
Nordfab Quick-Fit Ducting is manufactured in Thomasville, NC and Sparks, NV. Nordfab duct is a clamp-together
design using a rolled edge design with a single lever clamp. The ducting and clamps are made of similar materials.
During manufacturing the duct material sheet blanks, which are fi ve feet long, are rolled and fused together with a
laser weld process along the longitudinal seam. Each pipe is checked with a light apparatus for any welding fl aws
or gaps. The rolled edge is then die-formed after inspection by rolling each end of the pipe simultaneously. The
laser weld prevents any gaps in the rolled edge from forming. This rolled end is used for clamping components to-
gether as well as offering reinforcement every fi ve feet. 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. An ePTFE gasket
option is available for food grade and high temp applications. Nordfab Quick-Fit Ducting is available in 1” incre-
ments sized 3” to 24” diameter.
Engineering Specifi cation:
1. Ducting shall consist of the following:
a. Galvanized: ASTM A527 with a G90 rating
i. Temp rating is 500° F with no breakdown of zinc - Zinc melting point is 740° F
b. 304SS: Finish meets ASTM A240
i. Temp rating is 1,100° F
c. 316SS: Finish meets ASTM A240
i. Temp rating is 1,100° F
2. Ducting manufacturing techniques:
a. Diameters 3” - 24” pipe, adjustable nipples, and collars attached to other components will have one
or both ends die formed-rolled to provide a uniform edge around the circumference of the rolled
end. The pipe and adjustable nipples shall have the longitudinal seam laser welded to allow for a
tighter slip joint and reduce system pressure losses. All laser welded seams will undergo a light test to
ensure there are no voids or imperfections in the system. Pipe lengths using laser welded seams will
not exceed a nominal 60” length. The rolled edges provide structural support at 5’ intervals or less
and can be interpreted as a stiffener where SMACNA specifi cations are required. An adjustable
nipple is used for adjustment during the install process. Pipe is cut to appropriate length and the
adjustable nipple secures the pipe for install.
b. Pipe and other components larger than 24” shall utilize either an angle fl ange or fl at fl ange attached
loosely and retained in place using a 3/8” vanstone lip. The pipe shall have a compressed-interlocking
lap form seam and not exceed 78” in length. The angle or fl at fl anges provide structural support at
6’-6” intervals or less and are considered as stiffeners where SMACNA specifi cations are required.
c. There will be times when certain components will be air direction sensitive. These components will
have an arrow sticker attached showing the proper fl ow direction.
d. All ducting and its components shall have been tested to 80” WG using the following
gauged reference:
i. 3” will use 18ga material thickness
ii. 4” through 12” will use 22ga material thickness
iii. 13” through 29” will use 20ga material thickness
iv. 30” and above will use 18ga material thickness

COLLAPSIBILITY & LEAKAGE DATA
COLLAPSIBILITY STRENGTH OF “Q-F” PIPING
Each size of piping has been tested for strength against collapsing. The piping was exposed to constant
positive pressure and constant vacuum. Each pipe was exposed to a maximum capacity of the test equipment
of 80” WG of vacuum and positive pressure. None of the pipe showed any form of deformation during the test.
Please take into account that our 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 stronger than any pipe in
its class. Pipe and fi ttings must be installed in accordance with NORDFAB’s standard specifi cations and
standard accepted practices.
LEAKAGE RATE
All fi t together ducting systems allow for some degree of leakage where they are joined. “Q-F”
ducting is no exception and is not sold as an airtight system. However, versus the other ducting
typically used in fi t together systems, Nordfab’s Quick-Fit (Q-F) ducting has fully welded, leak-tight
laser welded seams. Spiral and other ducting with lock form seams are NOT fully welded at the seams
and can be expected to have higher leakage rates than “Q-F”.
In addition to our standard Nitrile gasket, NORDFAB also offers special clamp gasket material for high heat,
food applications, etc. Further, the applying of sealants to the individual rolled ends can enhance the tightness
of the system. However, the “Q-F” system is sold as a quick way of installing and modifying duct-work while at
the same time retaining the usability of each component. In short, “Q-F” is meant to be able to be taken apart,
re-assembled, stored, or moved. Completely eliminating the possibility for leakage jeopardizes the inherent
benefi ts of the duct. Standard “Q-F” is designed to provide tight sealing and effi cient airfl ow under negative
pressures. To that end, we are providing the following information for piping situations where fan sizing is of
extreme importance. The following data was obtained using standard components and was performed in ac-
cordance with the SMACNA, “ HVAC AIR DUCT LEAKAGE TEST MANUAL”. The information gives the leak-
age rate per joint of duct at various pressures. To utilize the chart, count the number of clamps, (this equals the
number of pieces), per size and multiply by the number given beside the corresponding diameter and under the
applicable pressure. These numbers assume that the product is correctly installed; free of dents in the joining
ends and that the gasket is in place. Special gasket material and sealants will increase the sealing capabilities.

Quick-Seal Clamps
Since 1986, the Nordfab Quick-Fit clamp has
been the world’s best selling and best sealing
duct clamp. It has set the standard for use in
industrial dust, mist, smoke and fume collection.
Many have tried to imitate it, but we’ve found
none who have ever matched, or improved upon,
its tight, leak-resistant seal.
Until now...
The New Nordfab Quick-Seal clamp uses our
new revolutionary “overlap” design. This ensures
the tightest seal possible.
Additionally, we have lengthened the handle for
the Quick-Seal clamp and made it stronger, giv-
ing you more leverage to clamp down for super
tight seals.

THINGS TO BE AWARE OF WHEN ORDERING “Q-F”
1. Order one clamp per “Q-F” component.
• One duct = one clamp
• Two elbows = two clamps
2. Specify dimensional information to speed up process:
• Transitions A,B,D,L,X, Y and fl ange style
• Branches A x B x C, or A x B x D, or A x B x C x D
• Tap-In or In-cuts A, B
• Reducer All diameters and end style
THERE IS NO SUCH THING AS TOO MUCH INFORMATION !
3. Look for 60 degree elbows to compliment standard branch orders with 30˚ tap. This is typical application
since the two components will create a perpendicular run to the trunk line.
4. Ask for fl ange styles, hole patterns, ID, OD, when applicable. Typical components
requiring fl anges will be parts that connect to fi lters, fans, or other types of equipment.

SIZING ELBOWS
The catalog lists the standard sizes and the standard gauges; however, NORDFAB also makes elbows in long
radius and in heavier gauges. The elbows can be made in segments or can be made smooth walled. Pricing for
the various sizes and gauges should be obtained by calling NORDFAB.
SPECIAL COMPONENTS
As with the elbows, NORDFAB is able to provide special hoods or special designed pieces for almost any dust
collection application. To obtain help in design or pricing, call NORDFAB.
ADAPTING TO EXISTING SYSTEMS
There will be instances where the customer will desire to apply “QF” duct to an existing ducting system;
NORDFAB makes adapters for this purpose. We can provide these in fl ange to “QF” or through simply
supplying “raw to QF” adapters that can be attached to the end of existing spiral duct so that “QF” can be
coupled to the duct.

EXAMPLE: Always work from your machines back toward the fi lter. Suppose that you have
a 5” drop that rises and runs back to join with a 6” drop as sketched above. What size
branch will you need?
The 5” pipe carries 615 CFM at 4500 FPM, (See Chart). The 6” pipe will need 885 CFM at
the same velocity (See Chart). Added together you have a total of (615 + 885) 1500 CFM
coming together. Looking again at the chart under 4500 FPM, you fi nd that 1500 CFM is not
listed, but falls very close to the 1570 CFM listed for an 8” pipe. This indicates that the 5”
joined to the 6” will require an 8” pipe to carry all of the material at the right velocity.
The branch, therefore, will be 8” on the downstream end reducing down to a 5” with a 6”
branching off of it. That is listed as a 8-6-5 branch.

The Standards
Various NFPA standards require that a dust collection system
has a means of preventing the
transmission of energy from a fi re
or explosion to the building/work
area. Through extensive testing by
a third party testing facility, Nordfab
has developed the Explosion
Isolation Flap (EIF) type CARZ to
be installed upstream of the dust
collector.
How it works
Under normal operation the fl ap will open as the downstream air
moving device generates a fl ow in the ductwork. Should an explosion
happen in the downstream equipment - like a dust collector - a
pressure front develops in the ductwork within milliseconds and due to
the design of the EIF, the internal fl ap will be forced closed and seal off
the approaching fl ame front. This prevents glowing embers and
burning material from
entering into upstream equipment
and spaces.
The Design
The design of the EIF is critical as the fl ap must function in millisec-
onds and therefore must be of light construction but must be strong
enough to withstand the explosion pressure.
Many full scale tests were performed to arrive at the proper design and
assure proper function.
The Tests
Since the EIF is a safety device, Nordfab submitted the EIF to rigorous
testing by an accredited testing facility in accordance with 94/9/EC Directive.

INSTALLING TAP-IN OR CUT-IN
STEP 1:
Temporarily place the in-cut on the main trunk in the required position, and while holding in place,
place hand inside of branch and trace the interior of the branch on trunk line where it needs to be cut out.
STEP 2:
Take down in-cut and drill a starter hole in the main trunk along the line traced from the branch. Then
using metal snips or a reciprocating saw, cut out metal piece that has been traced. File or grind any
sharp edges to insure effi cient fl ow.
STEP 3:
Now use an industrial strength silicone sealant to seal between in-cut base and main trunk.
STEP 4:
Use small sheet metal screws or a banding type clamp material to secure in-cut to the main trunk line.

are manufactured in type 302
S26 Stainless steel
Wire Rope Entry
The wire rope is pushed into
the Gripple in the direction
of the white arrows
Setting Key
Entry hole
Serrated Teeth
Each wedge makes
contact with the rope
using serrated teeth.
These bite onto the
wire rope and spread
the load across the
length of the wedge
maximizing grip while
maintaining wire rope
strength.
Locking Wedges
Oil impregnated steel locking
wedges, one in each channel,
allow entry of the rope in one
direction as the spring is
compressed, but creates
a vice-like grip as the load
is applied in the opposite direction.
End-Cap
The plastic end-cap, which is
made from a UV stabilized
homopolymer polypropylene
simply holds the spring in place.
Anchor Point
As the wire rope passes
through one channel, it is
wrapped around a suitable
anchor point before being
pushed through the second
channel.

2) Carefully place the gasket along the rolled edge
of the part, being careful to avoid kinks or voids.
Only one gasket is needed per joint.
3) Join the gasketed end of the pipe to a
non-gasketed end of the next part in the ducting
run using a standard Q-F clamp. The oil-mist
gasket, in addition to the gasket inside the Q-F
clamp, provides dual protection against leakage.

1) Wipe rolled edge with clean cloth. Then apply a
high tack gasket adhesive per the manufacturer’s
instructions. High tack gasket adhesives can be
purchased locally at industrial or automotive
suppliers in either aerosol spray or brushable
formulations.

LEAK-FREE GASKET INSTALLATION
The molded Nitrile gaskets slip easily onto one end of the duct and are connected with a standard Q-F clamp to form
a tight and re-useable seal. Note the direction of the airfl ow when installing the duct.

INSTALLATION OF ADJUSTABLE NIPPLE
FOR OIL MIST OR WET APPLICATIONS
The patented Nordfab “adjustable nipple” provides
unlimited fl exibility in the length of a duct run.
1. Cut a standard piece of pipe to length and insert
it into the short adjustable nipple section. This
assembly will telescope to any length. Place the
soft grey (or black with grey mark) o-ring seal
onto the cut (inside) piece of pipe and seat it
evenly against the rolled metal edge of the
adjustable nipple.
2. Place the harder black o-ring seal against the
outside of the inner grey seal.
The order should be as follows:
a) rolled edge or nipple; against
b) soft, small-diameter o-ring; against
c) standard Nordfab o-ring
3. Finally clamp the standard Q-F clamp over the
rolled metal edge of the adjustable nipple and
the hard rolled black o-ring for a leak-free con-
nection. [Make sure both seals fi t completely
under the clamp and that the air-fl ows from the
cut pipe towards the adjustable nipple].

SIZING A “Q-F” SYSTEM
NORDFAB offers assistance to those sales people and customers who have never designed a ducting system
before. We can assist you in determining the correct duct size and confi guration that will supply you with the
correct fl ow.
We have the ability to assist customers in designing a blast-gated system; taking into account fl ow dynamics
that will be affected by blast gates. While blast gates can be used to effectively utilize an undersized fi ltering
system, they can also destroy the fl ow if not properly placed.
USING THE CFM / FPM CHART
Different materials need to be moved at different velocities to prevent the material from falling out of the air
stream. For example: wood chips and saw dust fl ow well at 4500 feet per minute. Referring to the chart on the
next page, you will see that a 4” duct will convey 395 CFM at 4500 FPM. This will mean that a 4” pick-up on a
machine will take 395 CFM from your fi ltering system; or working in reverse, if you know that a machine will
require approximately 400 CFM to remove the waste, then you should design a 4” duct for the purpose.
