Structural features of square ducts
Structural features of the product include:
1. Classification
Square air duct is a type of air duct mainly made of galvanized steel or stainless steel. With a variety of galvanized corrugated iron pipes including: 0.48mm, 0.58mm, 0.75mm, 0.95mm, 1.15mm Along with many types of galvanized with different galvanizing levels such as Z8, Z10, Z12, Z18,… .
With the type of stainless steel ductwork including 2 main types, stainless steel 201 and stainless steel 304, each type will be divided into many small types with two distinct glossy and matte forms. Polished stainless steel has a higher price than matte stainless steel. In which, galvanized corrugated iron pipes are more commonly used due to the appropriate cost.
2. Thickness
The thickness of the product is calculated based on the largest side size of the duct as well as what system the duct is used for. All are according to the standards of the design unit as well as the individual requirements of the customer.
3. Length
Square ducts have their length L depending on the size of the corrugated iron as much as possible. The standard C brace duct is 1180 and the TDF – TDC is L1110. The type of square ductwork TDF – TDC is considered the most used type today.
Outstanding advantages of square ducts
The square air duct design helps better circulation, creating favorable conditions without affecting the air flow.
+ Square ducts are used in a variety of ventilation systems, they are connected to each other through C-clips, flange clamps, bolts or valve accessory systems, to create a complete pipeline system. for the entire construction project.
+ In addition, the square air duct is also quite light in weight, which can be easily moved to the location to be installed.
Square duct manufacturing process
Ducts are manufactured through the following stages
1. Prepare materials for processing ductwork
- Galvanized steel sheet, stainless steel
- Measure
- Machines
- Accessories such as cutters, screws, pliers…
2. Production steps
Step 1: Proceed to cut the stainless-steel sheets
After you have prepared all the materials, you proceed to cut the stainless-steel sheets into small pieces. Then the piece of stainless steel is transferred to the cutter, cut according to detailed technical drawings. This cutting is done with a CNC plasma cutter and is then transferred to the accessory-making unit.
Step 2: Create an accessory product
The forming process is done by machine or by hand. For some products, the folding edge is supported by a modern corrugated iron folding machine, the two connecting edges are fixed together by the edge of the accessory.
In particular, the process of creating a round coupling head is done through a pipe mold machine, the two joints are fixed by a spot welding machine, and then connected through a round neck joint on the square end of the duct.
Step 3: Finish the product
The finishing process includes a number of main stages, which are into the ke. Ke helps the product system to be firm and is also the location for the connection of duct fittings with other products.
The next step is to perform the spray painting process. This process helps to shield the welds, which enhances the aesthetic properties of the product.
In order to ensure that the product is not distorted, a hardening process is also performed. The commonly used hardening method is stiffening with treaded tires and stiffening with V flanges to complete stainless steel square air ducts.
