FLAT OVAL DUCT
PRODUCT AND CONSTRUCTION DATA:
- Flat oval duct is machine-made from round spiral lockseamed
duct. The oval shape produces less of a flat surface therefore making it
less susceptible to vibration than rectangular ducts which reduces the need
for rod and angle iron reinforcement.
- Flat oval duct can be supplied in lengths of up to 12 feet,
producing fewer joints to reduce friction loss and installation costs.
- The hanger installation details applicable to rectangular
duct are generally applicable to flat oval duct.
- The equivalent round is used to find the friction loss.
FEATURES:
- Airtight 4-ply lockseam;
- Low friction loss;
- Light weight;
- Long lengths.
BASE MATERIALS:
- Aluminum;
- Cold rolled steel;
- Galvanized steel;
- Perforated steel;
- Polyvinyl chloride (PVC) coated steel;
- Pre-painted steel;
- Stainless steel;
- Wiped coat.
PROFILE SELECTION
All the sizes in this catalogue are based on Type 2-LC profile
which
has two light reinforcing corrugations for added strength. It is light in
weight, economical and will not develop excessive pressure losses
at low velocities.
