An alphabet letter in the table means that reinforcement angles or their equivalent must be used at the foot interval following the letter. The angle sizes are:A = 1” x 1” x 1/8”; B = 1-1/4” x 1-1/4” x 3/16”; C = 1-1/2” x 1-1/2” x 3/16”; D = 1-1/2” x 1-1/2” x 1/4”; E = 2” x 2” x 3/16”; F = 2” x 2” x 1/4”If companion flange joints are used as reinforcements, those for 25” to 36” diameter shall be 1-1/2” x 1-1/2” x 3/16”; for 37” to 48” diameter 2” x 2” x 3/16”; for 40” to 60” diameter 2-1/2” x 2-1/2” x 3/16”; for 61” to 72” diameter 3” x 3” x 1/4”.

Installation of slip joint connectorsDuct-to-joint connections are made by using a duct coupling that slips inside the duct sections.

Duct-to-fitting connectionsDuct-to-fitting connections are made by slipping the fitting collar into the duct.

Fitting-to-fitting connectionsConnections can be made by using a short section of duct or by using a fitting coupling.

OVAL DUCT SYSTEMSTA M B E M E T A L P R O D U C T S

Flat oval duct combines the advantages of round duct and rectangular duct because it may fit in spaces where there is not enough room for round duct, and it can be joined using the techniques of round duct assembly.

Spiral flat oval duct is machine-made from round spiral lockseam duct and is available in varying sizes and aspect ratios. It can be made with longitudinal seams.

Flat oval duct has considerably less flat surface that is susceptible to vibration and requires less reinforcement than a corresponding size of rectangular duct. The deflec-tion of the flat oval duct under pressure is related to the flat span rather than the overall width of the duct.

Any round duct fitting can have an equivalent fitting made in flat oval. As in rectangular duct, a hard bend elbow denoted the plane of the duct width, whereas an easy bend elbow denotes the bend in the plane of the duct height. Any branch fitting can be made with the branch tap either round or flat oval. The tap of the flat oval fitting can be located anywhere on the circumference of the fitting body. If the diameter of a round tap is greater than the height of the flat oval body, a transition can be made from flat oval to round, providing an equivalent area at the base of the transition.

Flat oval duct is for positive pressure applications only unless special designs are used.

Single wall slip fit1. The fittings are male sized to slip into the pipe section. A good tight fit is necessary for minimalizing friction loss and good sealing. Care should be taken during handling to avoid any dents or distortions that can cause improper fit and difficult installation.

2. A sharp blow to the top of the collar with hand or sheet metal mallet can cause the collar to seat into the duct. For larger sized duct, straddle the duct and slightly compress duct sideways while another person jiggles the fitting into the duct.

3. As a last resort, a half moon cut on the top of the collar to eliminate the “high-spot” and the fitting slips easily into place.

Double wall slip fitThe inner and outer collars of fittings are male sized and designed to slip into the connecting duct. The inner collar projects beyond the outer collar permitting the inner collar to be started into the inner liner of the duct section similar to the single wall technique.

1. Bring bottom of inner collar into the duct section at a slight angle.

2. Using slight pressure, work the rest of the collar into the duct.

3. When the inner collar is fully started into the duct, start the outer collar in the same manner. Tilt the bottom edge slightly upon insertion and tap the “high-spots” to work the collar into the duct.

It is suggested to save time, sub-assemblies be made on the floor then hoisted into place.

Additional suggestions for installation1. Rest your duct on two blocks of wood and then using your hands and moving the duct, in an up and down motion, will help you make your connection without damaging the duct.

2. Allowances have already been made in fittings for installation. Should a kink occur through handling, by carefully straightening out the kinks and bends a good connection can still be made.

3. DO NOT use a hammer and screwdriver to make a connection. The possibility of causing damages internally is a real danger to friction loss. Apply pressure with the heel of your hand or a good thump with your fist can help the fitting slip into the duct.

4. Apply duct sealant to the internal end of the spiral approximately 1” and apply duct sealant around the slip part of your fitting. As the fitting slips into the spiral duct the sealant will not scrape off in the slip connection.

5. Whenever possible brush your internal joint to make it smooth inside and out; also, inspect your sealed joints for coverage. One to two days after completing the connections check connections for shrinkage of the duct sealant. Reapply sealant where needed.

2” W.G. Reinforcement

To use this table:1. Find the minor axis of the oval size you wish to reinforce in the first row.2. Go down the column for that minor axis until you reach the major axis of the oval size you wish to reinforce.3. To the left of the major axis you will find the appropriate reinforcement.
