What is ductwork fabrication?

What is ductwork fabrication?

Sheet metal duct fabrication involves cutting and forming processes. Cutting uses shears and specialty high-definition plasma equipment, and forming uses brakes and presses to exert applied force to shape the material.

How do you design duct size?

To calculate the required equipment size, divide the HVAC load for the entire building by 12,000. One ton equals 12,000 BTUs, so if a house or office needs 24,000 BTUs, it will take a 2-ton HVAC unit.

How do you install ductwork?

How to Connect Duct Work

1. Step 1: Crimp One End. Select standard duct pieces for the connection that have crimped and uncrimped ends.
2. Step 2: Insert Duct Into Next Piece. Insert the crimped end of the round duct into the uncrimped end of the next round duct.
3. Step 3: Tape the Seams.
4. Step 4: Screw the Pieces Together.

How many types of ducting are there?

There are three main types of rigid ductwork: sheet metal ducts, fiberglass lined ducts, and fiberboard ducts.

What is HVAC full form?

What type of sheet metal is used for ductwork?

Galvanized mild steel
Galvanized mild steel is used most often for building ducts. This material’s zinc coating helps prevent corrosion and rust buildup. Its versatility also allows fabricators to design ducts in different shapes to meet specific installation needs.

What is duct layout?

A duct system is also called ductwork. Planning (laying out), sizing, optimizing, detailing, and finding the pressure losses through a duct system is called duct design.

What is duct sizing?

Duct sizing depends on multiple factors like size of your home, air flow velocity, friction loss and static pressure of the HVAC system. The size of your duct work depends not just on the size of your entire house but also on the size of each individual room.

How are ducts joined?

Joining duct pieces together with slip joints simply means slipping each part into the next and fixing with screws or rivets. The ducts are prepared during manufacture to enable a male/female connection (sometimes referred to as a ‘socket & spigot’ connection).

What type of metal is used for ductwork?

Made of galvanized steel or aluminum, rigid sheet metal is the most common type of ductwork. The thick, solid wall makes the duct very durable. The interior is known to trap dust and other particles, but the smooth surface is generally easy to clean.

How to produce metal air ducts?

Production process of metal air duct: 1. Field measurement 2. Actual sketching 3. Sheet correction 4. Underlining 5. Unfolding 6. Blanking 7. Closing of the air duct 8. Welding form of air duct 9.

How to select the plate thickness of the air duct?

(1) Select the plate thickness according to the different specifications and sizes of the air duct. Then leave a closing edge to make allowances for unloading. (2) The line drawing method should be strict, so that the angle is straight, the line is flat, and the aliquots are accurate, the geometric size should be checked frequently.
