Process and equipment required for air duct processing and production
First, the process of processing and production of air ducts
There are many types of air ducts, different air duct production process is different, to the commonly used metal air ducts as an example, its processing and production process is as follows:
1. Approval of air duct size. According to the design requirements, drawing review minutes, combined with on-site measurement data to draw the air duct processing sketch, and indicate the system air volume, wind pressure determination hole location.
2. Duct expansion. According to the air duct construction drawings (or release diagram) the surface shape of the duct according to the actual size of the sheet; unfolding method there are three kinds of that is, parallel line unfolding method, radial line unfolding method and triangular line unfolding method.
3. The sheet must be checked before cutting, and then cut according to the scribed shape after checking.
4. After the sheet is discharged in the press before the mouth, must use the chamfering machine or scissors for chamfering.
5. Splicing of plates. And round ducts of the closed bite can be used single bite; rectangular ducts or fittings of the four corners of the combination can be used corner bite, joint corner bite, snap bite; round bends can be used in the combination of vertical bite, bite width and stay according to the thickness of the plate, the bite to stay in the size of the bite, the width of the bite and the number of overlapping layers with the use of machinery.
6. Draw a good folding line, in the folding machine on the folding square. When making round ducts, the ends of the nibbles will be patted into arc shape and put on the rounding machine to roll round.
7. Fold the square or roll the round steel plate with a sewing machine or manual sewing. When operating, the force is even and should not be too heavy. The combination of nibble seam should be tight, and there should be no swelling and half nibble phenomenon.
8. Reinforcement of air ducts: air ducts can generally be reinforced with fluting, standing bars, angles, flat steel, reinforcing bars and pipe supports.
Second, what equipment is needed for air duct processing
Processing air ducts need to use a lot of equipment, generally the following:
1. nibbling machine: presses the metal plate into a special shape so that the parts can be locked together to form a strong component that will not be easily separated.
2. bending machine: used to bend metal plates into a desired shape.
3. Hydraulic Shears: Used to cut sheet metal using a hydraulic press.
4. Hydraulic Shelf: Used to store and transport sheet metal or coils.
5. Hydraulic Rivet Pliers: Used to remove damaged rivet protrusions.
6. Offset Tri-Star Roller Coiler: Can be used to transport pipes, metal bars, metal sheets, etc. and continuously bend them at a specific angle.
7. Duct Seaming Machine: Simply put the completed duct into the vertical seaming machine to complete the final step of duct seaming.
8. Round elbow nibbling machine: for round pipe nibbling and closing to make elbows, the same machine can be both nibbling and closing.
9. CNC plasma cutting machine: used to cut out specific shapes from metal plates.
10. spiral duct machine: used to make metal bars into a spiral pipe, replace different sizes of mold molding different sizes of round pipe, so that the duct size is more accurate and uniform, stable pipe size, sealing performance and molding effect, molding process is more stable and fast.
Third, the air duct production line should have what function
Duct production line is an assembly line for producing ducts, the whole process of duct forming is completed independently by the assembly line, a complete duct production line should realize the following functions:
1. Coil material selection, discharging function; you can choose 2-6 kinds of different thickness or material of the coil material.
2. Pressing and flattening function: this function is the adjustment process before processing the coil material to prevent the production of waste material.
3. Punching, chamfering and grooving function: this function can complete the production of air duct installation holes, avoiding the inconvenience caused by later punching.
4. Cutting function: this function will detach the sheet from the coil for the next processing.
5. Transfer function: It is convenient for the coil material to be processed automatically in the next process.

Comparative Overview: PIR Duct vs. Phenolic Duct in HVAC Systems
In modern HVAC systems, the choice of duct materials significantly impacts overall efficiency, safety, and longevity. Two prominent materials used in duct construction are PIR (Polyisocyanurate) and Phenolic. This article aims to delineate the key differences between PIR and Phenolic ducts, focusing on their characteristics, advantages, and best-use scenarios.
Material Composition
PIR Ducts:
PIR ducts are made from Polyisocyanurate foam, a type of thermoset plastic. This material is characterized by a closed-cell structure that provides robust thermal and moisture resistance. PIR ducts are typically reinforced with aluminum foil on both sides, which adds to their strength and insulation efficiency.
Phenolic Ducts:
Phenolic ducts, on the other hand, are constructed from phenolic foam derived from phenol and formaldehyde. This foam has a fine cell structure that offers excellent thermal insulation. Similar to PIR ducts, phenolic ducts are usually clad in aluminum foil, enhancing their durability and insulation properties.
Thermal Efficiency
PIR Ducts:
PIR foam is renowned for its thermal insulation capabilities, with a thermal conductivity (lambda value) around 0.022-0.026 W/m·K. This means PIR ducts can achieve high levels of thermal resistance with relatively thin insulation, making them a practical choice for installations where space is limited.
Phenolic Ducts:
Phenolic foam slightly outperforms PIR in terms of thermal conductivity, typically ranging from 0.018-0.025 W/m·K. This superior thermal efficiency makes phenolic ducts highly suitable for applications where energy conservation is critical, as they provide better insulation with thinner material.
Fire Safety
PIR Ducts:
PIR ducts offer moderate fire resistance. The material is self-extinguishing, meaning it will cease to burn once the ignition source is removed. However, PIR foam can produce more smoke and potentially hazardous gases compared to phenolic foam when exposed to fire.
Phenolic Ducts:
Phenolic ducts are notable for their excellent fire resistance. Phenolic foam is highly resistant to flames and produces minimal smoke and toxic fumes when subjected to high temperatures. This makes phenolic ducts particularly advantageous in settings where fire safety is paramount, such as commercial buildings and areas with high occupancy.
Advantages and Applications
PIR Ducts:
Thermal Insulation: High efficiency in minimizing heat transfer, ideal for energy-conscious installations.
Moisture Resistance: Suitable for humid environments due to its closed-cell structure.
Durability: The aluminum foil facing provides additional protection and structural integrity.
Phenolic Ducts:
Fire Resistance: Superior performance in fire safety, emitting low levels of smoke and toxic gases.
Thermal Efficiency: Slightly better thermal insulation properties, beneficial for stringent energy standards.
Lightweight and Strong: Easier to handle and install while maintaining robustness.
Practical Considerations
PIR Ducts:
PIR ducts are well-suited for residential and commercial applications where thermal insulation and moisture resistance are critical. Their lightweight and durable nature make them easy to install, even in complex ductwork systems.
Phenolic Ducts:
Phenolic ducts are often chosen for environments that prioritize fire safety, such as hospitals, schools, and high-occupancy buildings. Their superior thermal performance also makes them ideal for projects aiming for the highest energy efficiency standards.
Conclusion
Choosing between PIR and Phenolic ducts involves evaluating specific project requirements, including thermal insulation needs, fire safety considerations, and environmental conditions. PIR ducts offer excellent thermal and moisture resistance, making them versatile for various applications. Conversely, phenolic ducts provide exceptional fire resistance and slightly better thermal performance, making them ideal for high-safety and high-efficiency settings.
By understanding the unique properties and benefits of each duct type, HVAC professionals can make informed decisions that enhance system performance, safety, and longevity.
