Spiral pipe combines the economies of light gauge metal with a spiral lockseam construction that assures maximum strength and rigidity. As a result of its superiorstructural strength, the ductwork requires fewer joints and hangers. Four plys of metalform a continuous interlocked reinforcing rib on the outside which permits making longlengths of pipe in various diameters from strip stock of specified gauge.Developed for use on high velocity, high pressure air conditioning systems,Spiral pipe has gained wide acceptance for all types of high or medium pressure,above and below ground distribution systems, such as ventilation, dust removal, grainhandling, carbon monoxide exhaust and dual wall pipe for sound and thermal insula-tion. These are only a few of its diversified applications.Spiral pipe is available in other materials on special order, such as vinyl-coated steel,brass, copper, aluminum and stainless steel. Spiral galvanized pipe is carefully engineered and built, to meet or exceed all SMACNA standards (Sheet Metal AndContractors National Association).Standard length in all diameters is 10 feet. Any length between 6 and 20 feet cut atno additional charge. Sizes range from 3" to 18" @ 1" intervals and 20" to 80" @ 2"intervals.Spiral vinyl-coated pipe is manufactured from galvanized steel coated withpolyvinyl chloride material, with an outside thickness of 4 mils and inside 1 mil,standard. This is reversible for special purposes. External Corrugations are recommended for over 14" diameter for underground applications. Standard gaugesare: 4" to 16" / 24 gauge, 17" to 24" / 22 gauge, 26" to 48" / 20 gauge.

A complete line of seam welded slip-joint fittings, designed especially for use with Spiral pipe, includes many types of elbows, crosses, tees, laterals, reducers and various accessories, fabricated from 20 gauge (other gauges available).

Special Made FittingsSpecial items are made on a time and material basis. Once accepted for production,they cannot be cancelled, nor returned for credit. Check MeasurementsCarefully!

Performance Characteristics

Duct liner absorbs equipment and air rush noisesover a broad spectrum of sound. Glass fiberconstruction traps noise and dissipates it within thefiber matrix. Air is delivered, not noise. It also performsas a thermal insulation to conserve energy.Three l-beam spacers minimum at approx. 120centerline spot welded to inner duct.Zinc on galvanized pipe melts at 788 F.The Manual of Industrial Ventilation RecommendedPractice, 23rd Edition, suggest operating temperaturesnot to exceed 400 F.Standard duct liner maximum temperature rating 250 F.R-value = 3.6 per inch of thickness.

K factor is expressed asbtu./ in./ hr./ ft2/ deg. F.

R is the reciprocal of K.

All values are measuredat 75 F. mean temperature.

INSTALLATION OF SPIRAL PIPE AND FITTINGS

1. Fitting-to-Fitting connections are made with a female (C-1-F) coupling or a short length of Spiral pipe. They are sized to slide over fittings.

2. Fittings and Small-End couplings (C-1) have male ends. They are sized to slideinside Spiral pipe and flexhose.

3. Spiral pipe is joined by means of couplings and sealed with duct sealer. Sheet metal screws or pop rivets are used at maximum 15'' intervals, with a minimum of three fasteners per joint. These hold the fittings and joints in place while the sealant cures.

Sleeve type couplings (C-1) con-nect Spiral pipe together. Thesmall ends of the coupling areslipped into the pipe sections.

Pipe sections mate with fittingsthat are sized to slip together.No extra coupling is needed.

Bolted Vanstone flanges are usedto connect pipe and fittings togeth-er. Order pipe or fittings with flangeinstalled or see below for your owninstallation of flanges.

Installation of Vanstone Flange

FaceStep 1. Slip flange over Spiral ductwork allowingduct to extend 1/2 beyond the face of the flange. Measure to ensure the flange is square to the duct.Secure flange in place with 3 or 4 C-clamps.

Step 2. Peen 4 tabs about 1 wide and 90o apart, working from the inside of the flange. The edge of the flange acts as a break.Do not cut, slice, or hammer directly on the end of the duct.

Step 3. Rotate duct 45o and peen 4 more tabs about 1 wide and 90o apart. There should now be a total of 8 tabs bent over.

Step 4. Peen remaining edge of duct over flange. Flange is ready to be bolted.

STEP 2

STEP 4

Cut a short length of Spiral ductso a fitting-to-fitting connectioncan be made. Use this shortlength of duct as a female cou-pling or order a (C-1-F) femalecoupling.

Typical Design of A DustCollection System

The following is an abbreviated example of a small wood chip and sawdust system. There are manyvariables for the pneumatic transport of particle material, therefore, this is only a snapshot of one typeof small system.Terms frequently used, you should know.CFM- Cubic Feet per Minute (air volume)FPM- Feet Per Minute (velocity of air)S.P.- Static Pressure. expressed in inches of water. It is resistance to air movement in a

duct. Also called pressure loss, friction loss, system resistance, etc.Floor PlanStart with a floor plan of your shop area, show at least the following:1. Location of dust producing machines including the size and location of dust pick-ups.2. Location of dust collector unit.3. Measurements from floor to joists.4. Obstructions that will interfere with runs.5. Best estimates of locations and length of branch ducts and main dust.To specify your dust collector, ductwork and fittings, you must know:1. Required air velocities to carry chips (FPM).2. CFM required.3. Size of ducts to provide 1 and 2 above.4. Static pressure (S.P.) resulting from 1, 2, and 3 above.For this example we are going to choose minimum air velocity of 4500 FPM for the branch ducts and4000 FPM for the main duct. These velocities are taken from our guideline table on pages 51 and 52.

The total CFM required of the dust collector is 400 + 600 + 500 = 1500 CFM.

Now we must determine the static pressure (S.P.) loss of the assembled system.The total S.P. loss that the collector must overcome is the sum of the losses of:1. The branch with the greatest S.P. loss, which includes its length of duct and the S.P. losses

of the fittings used in this branch.2. The main duct with its various diameters (to be determined) and the S.P. losses of its

fittings.3. S.P. losses of flex hose.4. Entry loss at the machine adapter collars (use 1.5'' S.P. as a constant).5. Filter loss if used [(use 1.5'' S.P. as a constant) check with blower manufacturer].6. Pre-separator if used [(use 1.5'' S.P. as a constant) check with blower manufacturer].Calculations (with assumptions):

Lets assume that each branch duct uses 10 feet of duct three 45o elbows, one 90o elbow,one 45o lateral and 3 feet of flex hose.A rough look at the static pressure (S P) chart on page 48 indicates that the 4 inch Planer branch will have the worst S.P. loss. This is the only branch that needs to be considered in the summation of losses. The other two branches, which have less loss, will not contribute to the total loss.

Next we will choose only three hypothetical machines and their required CFM:

Jointer 400 CFM = 4 DuctShaper 600 CFM = 5 Duct (rounding up) Planer 500 CFM = 4 Duct

Calculate this branch as follows:The chart on page 48 approximates 10'' of loss per 100 ft of duct at 500 CFM.The branch has 10 ft of duct. Therefore 10/100 x 10'' = 1'' S.P. loss.

35

S.P.


Main Duct CalculationsLets now assume that the main includes the 15 foot length from the Jointer to the Shaper branch, then runs another 15 feet from the Shaper to the Planer branch, and finally 20 feet the rest of the way to the dust collector. Also, that it has two 90o elbows and 4 feet of flex duct to the dust collector.

Where the Shaper branch enters the main duct, it adds 600 CFM to the system and we want to reduce the velocity of the main to 4000 feet per minute (FPM).

Our Static Pressure chart on page 48 shows that 15 feet of 7'' duct will result in 0.5''S.P. loss ( 3'' x 15/100 = 0.5'') with 1000 CFM (400 + 600) airflow. The above 15 feet of 7'' duct contains one of the 90o elbows which produces 0.24'' S.P. loss.

Where the Planer branch enters the main duct, it adds still another 500 CFM to the system (continuing to flow at a velocity of 4000 FPM).

From the Planer to the dust collector is an 8'' Dia. run 20 feet long, one more 90oelbow and the 4 feet of flex hose.

The S.P. chart on page 48 shows 20 feet of 8'' duct produces .56 S.P. loss(2.8'' x 20/100 = .56'') with 1500 CFM (400+600+500) airflow.

To this we add another eight inch 90o elbow; 0.24''.Next we add the loss from 4 feet of flex hose from the chart on page 38.(4/100 x .3 x 27.58 = .33'')

Summing up the main = .5 + .24 + .56 + .24 + .33 = 1.9''Finally we must add 1.5'' S.P. loss for the filters.

Summing up the S.P. loss for the system we have:

Typical Design of A DustCollection System

(continued)

~

~

Worst branch loss (planer) = 5.7 S.P. lossMain duct loss = 1.9 S.P. lossFilter loss = 1.5 S.P. lossTotal system = 9.1 S.P. loss

Additional comments:If a return duct should have been necessary because of a remote location for the collector, it should

be 2'' larger in diameter than the main duct entrance to the collector (8''+2''=10'' dia), and its S.P. loss(it will be small) would be added to the total system loss.There should be a Blast Gate installed on eachof these three primary branches. Properly installed they should not increase static pressure loss.Additional secondary branches (those used intermittently) will not alter the calculations. The designassumes that all three primary branches may be used simultaneously.

The information to spec out the dust collector has now been determined. It wouldbe specified to a minimum of 1500 CFM with a static pressure capability of no lessthan 9.1 inches.Note: Some dust collector systems may not include fan curve information that shows CFM or static

pressure variables. We do not recommend procuring collector equipment without this kind of information.

Calculate this branch as follows:The chart on page 48 approximates 10'' of loss per 100 ft of duct at 500 CFM.The branch has 10 ft of duct. Therefore 10/100 x 10'' = 1'' S.P. loss.There are three 45o elbows. Each 3 gore elbow has approximately 0.3'' S.P. loss from chart on page 44. Therefore 3x0.3 = loss for the three 45o elbows (0.9'')

The one 90o elbow has 0.6'' of S.P. loss from chart on page 43.The 45o lateral has a S.P. loss of 0.5'' from chart on page 47.

Exhaust Volumes and Pipe SizesThis list of recommended exhaust volumes and pipe sizes for average sized metal working and woodworking machines is based on manyyears of experience and the work of many people. Some modern high speed or extra large machines will require higher velocities than shown.Smaller machines may use less air than shown. The air volume required to capture the dust at the machine will vary with each operation.Particle size and hood type must be considered.The following charts will provide an excellent guide to determine your total air volume require-ments.Caution: One of the most important factors in an efficient dust collection system is proper hood design. Hoods must be designed so that thedispersed particles are thrown or deflected directly into the hood opening. The large heavy particles thrown out by the cutting heads or wheelshave such a high speed that their trajectories cannot be altered by a vacuum system regardless of its velocity. In addition hoods should beplaced as close to the source of dust contamination as possible since the effectiveness of an exhaust hood decreases very rapidly as it ismoved away from the source. The following recommended pipe sizes are based on the use of reasonably good hoods.Wide belt and abrasive sanders, moulders and shapers with high R.P.M. spindles often call for higher duct velocity (through hoods supplied bymanufacturers) than those indicated on the charts. In these cases caution must be used.The following charts are recommended for machines with good hood enclosures. (Also check with the machine manufacturer for their recommended velocities.)
