GENERAL ENGINEERING SPECIFICATION FOR LASER QUICK FIT DUCTING

AS MANUFACTURED BY NORDFAB OF THOMASVILLE, NC

DUCT-WORK:

All duct-work shall be of a clamp-together design using a die-formed, rolled edge in which is then joined together by a single lever clamp of similar material. All clamp together ducting shall be of continuous laser welded construction along the longitudinal seam of the rolled form duct with the exception of the 3” which is lock formed. All connections shall have Nitrile seal in clamp for standard installs and a Gortex seal for mist or food grade applications.

Duct material sheet blanks are five feet long, which is then rolled and fused Together with a laser weld process along the longitudinal seam.

The ends of the duct are then pressed in a die to from a rolled bead on each end of the duct. This rolled-end is used for clamping components together as well as reinforcement every 5 feet.

COMPONENT MATERIAL:

Straight duct and other connecting components to be constructed of galvanized sheets produced by the continuous galvanizing process in which conforms to ASTM-A-527, and commercial quality ASTM A-527. Galvanized sheeting is produced with a minimum spangle with coating weight of G-90.

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. Should these levels of static pressure be required, we suggest an alternative seal be used in the clamp such as the white Gortex Seal. This increases the sealing properties on the connection joint.

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.

Sincerely,Niels PedersenPresident

All fit 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 standard Nitrile gasket, NORDFAB offers special clamp gasket material for high heat and enhanced sealing. 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 benefits 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 situations and should not be confused with the ducting that uses tape or gaskets as sealant in the positive conveyance of air.

COLLAPSIBILITY STRENGTH OF “Q-F” PIPINGEach 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. Pipe and fittings must be installed in accordance with NORDFAB’s standard specifications and normal good workmanship practices.

LEAKAGE RATEAll fit 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 standard Nitrile gasket, NORDFAB offers special clamp gasket material for high heat and enhanced sealing. 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 benefits of the duct. Standard “Q-F” is designed to provide tight sealing and efficient airflow 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 accordance with the SMACNA, “ HVAC AIR DUCT LEAKAGE TEST MANUAL”. The information gives the leakage 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 in place. Special gasket material and sealants will increase the sealing capabilities.

SMACNA ROUND INDUSTRIAL DUCT CONSTRUCTION STANDARDS OF 1999

The following gauge thickness reinforcement information is recommended for Class 2 Duct System.Subjected to a negative pressure of 10” water gauge.

Class 2 is defined as including applications with moderately abrasive particles in light concentrations: i.e. buffing, polishing, woodworking, grain dust etc.

Understanding that Nordfab duct comes in 5’ maximum lengths and has the rolled edge on both ends, it seems that the beads at the joints would act as reinforcement and by the use of the clamp the pipe is banded every 5’. This appears to be the only question that could be a gray area of our acceptance in the specifications. Velocities of 4500-5500 FPM and static pressures to 25” water gauge are within design criteria and our duct was originally and still is designed for the wood industry.

SIZING ELBOWSThe 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 with smooth wall. Pricing for the various sizes and gauges should be obtained by calling NORDFAB.

SPECIAL COMPONENTSAs 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 SYSTEMSThere will be instances where the customer will desire to apply “Q-F” duct to an existing ducting system. NORDFAB makes adapters for this purpose. We can provide these in flange to “Q-F” or through simply supplying “Q-F” adapters that can be attached to the end of existing spiral duct so that “Q-F” can be coupled to the duct.

FunctionOpens gates automatically when workstations are ON, closes gates when workstations are OFF. This unit controls up to 22 workstations and switches dust collector ON/OFF.

Upgrade an existing overcrowded dust collection system

In case your plant has expanded and you are left with an undersize dust collector, the ECOGATE PRO System can greatly improve system performance, without the expense of making your system bigger (you will save on electricity too and meet OSHA recommended safety levels).

New systemYour new dust collector can be designed 40% smaller than the standard design, or you can use conventional design size and this allows 40% expansion later.

Benefits Allows use of smaller dust collector, increases suction (air-velocity) at machines in use, and saves about 25% of electricity.

ComparisonWith other Ecogate systems

Cost effective solution, where greenBOX MASTER and variable speed drive are too expensive. Smaller unit greenBOX allows the connection of only 8 workstations and allows only limited length of cable between control unit and gate (best suited for small/medium factories).

ECOGATE DESIGNA

BC D E


Function When a machine is turned on, a sensor signals the greenBOX® controller to open the appropriate gate. When the machine stops, the gate closes. The greenBOX® MASTER monitors the usage of all machines in your shop and, through the Power MASTER™ unit continually optimizes the amount of power supplied to the collector fan. The system is programmed to keep a certain percentage of gates open to maintain proper airflow through the system.

Existing system

In case your plant has expanded and you are left with an undersize dust collector, the MASTER System can improve system performance, without the expense of making your system bigger.

New system Your new dust collector can be designed 40% smaller than the standard design, or you can use conventional design size and this allows 40% expansion later.

GRIPPLE HANG-FASTGripple Hang-Fast is a complete solution for hanging mechanical and electrical services. It comes as a ready-to-use suspension kit, available in a range of standard lengths, from 1m to 10m and sizes, with load ratings from 35 kg to 325 kg. Even custom made lengths can be manufactured on request. The comprehensive range ensures that installation times are minimized and high productivity is achieved on site.

The principal element of all Gripple Hang-Fast assemblies is the Gripple Hang-Fast Grip, which is not only used to terminate the rope but is also the means by which object height can be adjusted.

Gripple Hang-FastSizes & Working Load Limits ...

Zinc HousingBy using zinc, the product is able to combine majoranti-corrosion propertieswith strength and consistentmanufacturing quality.

Stainless SpringsThe springs, one in each cannel, are manufactured in type 302S26 Stainless steel

Wire Rope EntryThe wire rope is pushed intothe Gripple in the directionof the white arrows

Setting KeyEntry hole

Serrated TeethEach 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 WedgesOil impregnated steel lockingwedges, one in each channel,allow entry of the rope in onedirection as the spring is compressed, but createsa vice-like grip as the load is applied in the opposite direction.

End-CapThe plastic end-cap, which ismade from a UV stabilizedhomopolymer polypropylenesimply holds the spring in place.

Anchor PointAs the wire rope passesthrough one channel, it iswrapped around a suitableanchor point before beingpushed through the secondchannel.

RULE OF THUMB LABOR GUIDELINESA) Long straight runs and trunk-lines • “Q-F” duct = 6 to 10 man hours per 100’ • Flanged duct = 20 man hours per 100’

B) Machine Connections • Machine with 1 or 2 ports = 1.5 to 3 man hours per port. • Machines with 3 or more ports = 4 man hours per port.

A+B = TOTAL MAN HOURSOR

QUICK METHOD

(TOTAL # OF PORTS) x 3 HOURS EACH = “X”“X” x 2 = DUCTING SYSTEM TOTAL MAN HOURS

NOTE: The above methods should be used for comparison and budgetary purposes only!! By no means should they be used to confirm a job installation. It should be the sales person’s responsibility to analyze each individual job and make his/her own judgement.

THINGS TO BE AWARE OF WHEN ORDERING “Q-F”1. Order one clamp per “Q-F” component. • 1 - duct = 1 clamp • 2 - elbows = 2 clamps

2. Specify dimensional information to speed up process: • Transitions A,B,D,L,X, Y and flange 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 branch orders. This is typical application since the two components will create a perpendicular run to the trunk line.

4. Ask for flange styles, hole patterns, ID, OD, when applicable. Typical components requiring flanges will be parts that connect to filters, fans or other types of equipment.

INSTALLATION OF DUAL-GASKETING FOR OIL MIST OR WET APPLICATIONS FOR

NORDFAB STANDARD ROLLED EDGE PIPE

Standard Nordfab parts are well-suited for most dust, smoke and fume collection systems. However, on oil-mist or other “wet” systems, a dual gasket is recommended to eliminate leakage of materials condensing inside the pipe. Also industry or government regulations occasionally require dual-gasketing on certain dry or fume systems.

INSTALLING THE OIL MIST GASKET BETWEEN STANDARD ROLLED-EDGE SECTIONS OF PIPE.

1) 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.

2) 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

2



INSTALLATION OF ADJUSTABLE NIPPLE FOR OIL MIST OR WET APPLICATIONS

Installing a second O-Ring in a Nordfab adjustable nipple.

1) When a non-standard length of pipe is needed, use a standard Nordfab Adjust-able Nipple to span the gap.

2) Place the small-diameter soft o-ring between the standard o-ring and the rolled edge of the nipple. The soft o-ring should be seated evenly against the rolled edge.

3) Position the larger-diameter standard Nordfab o-ring above the oil-mist ring.

The order should be as follows:a) rolled edge or nipple; againstb) soft, small-diameter o-ring; againstC) standard Nordfab o-ring.

4) Clamp a standard Q-F clamp around both o-rings and the rolled edge. Make sure that both o-rings fit completely under the clamp.

NOTE: KEEP CUT PIPE IN THE DIRECTION AS THE AIR FLOW.

The chart will also allow you to determine the transitions and branches neededEXAMPLE: Always work from your machines back toward the filter, suppose that you have a 4” drop that rises and runs back to join with a 6” drop as sketched above. What size branch will you need?

The 4” pipe carries 395 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 (395+ 885) 1280 CFM coming together. Looking again at the chart under 4500 FPM, you find that 1280 CFM is not listed, but falls very close to the 1205 CFM listed for a 7” pipe. This indicates that the 4” joined to the 6” will require a 7” pipe to carry all of the material at the right velocity. The branch, therefore, will be 7” on the downstream end reducing down to a 4” with a 6” branching off of it. That is listed as a 7-6-4 branch.

All branches come off the duct at a 30 degree angle, so it is important to add a 60 degree elbow to complete a full 90 degree drop or turn. (See Diagram above) The “Q-F” catalog contains all pertinent data about the duct and sizes. With a few basic pieces of information, you should be well equipped to design a system. But, if you have any questions as to the design, please do not hesitate to call.

SIZING A “Q-F” SYSTEMNORDFAB 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 configuration that will supply you with the correct flow.

We have the ability to assist customers in designing a blast-gated system; taking into account flow dynamics that will be affected by blast gates. While blast gates can be used to effectively utilize an undersized filtering system, they can also destroy the flow if not properly placed.

USING THE CFM / FPM CHART

In the following pages, you will find information and a chart that allows you to pick the right size duct for the CFM that is required. Different materials need to be moved at different velocities so as to prevent the material from falling out of the air stream. For example: wood chips and saw dust flow well at 4500 feet per minute. Referring to the chart, 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 filtering 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.
