Spiral and oval ductwork are two types of ducting systems that play a crucial role in various industries, including HVAC, industrial ventilation, dust collection, bulk material handling, and specialized industries such as chemical, pharmaceutical, and food processing. These ducting systems are designed to provide efficient airflow, reduce pressure drop, and ensure durability and low maintenance.
When comparing spiral and oval ductwork to rectangular ductwork, several factors come into play, including performance, energy efficiency, and economic advantages. Spiral ducting has become increasingly popular over traditional rectangular ducting in HVAC and industrial applications because its curved shape offers distinct aerodynamic benefits. A smaller diameter spiral duct performs equivalent to a larger cross-section of rectangular duct at about the same static drop for transporting air.
Additionally, the installation process is simplified as supports are not required to prevent crushing caused by pressure variations along different points of the duct. This is primarily due to the absence of weak or kinked positions, which are common in square counterparts. As a result, spiral ductwork offers long-term savings alongside its minimalist aesthetic advantages, making it a highly desirable fixture.
What are Spiral and Oval Ducts Made Of?
Oval or spiral ductwork are a versatile and efficient solution for various applications, from HVAC systems to industrial ventilation and dust collection systems. By considering the specific requirements of the application and selecting the correct type of ducting, businesses can create a reliable and high-performance ductwork system. Regular maintenance and repair are also essential to ensure the system operates efficiently and effectively over time.
Spiral and oval ductwork is available in various materials, each with unique characteristics and applications:
* Galvanized steel spiral ducting is a cost-effective option with an available zinc coating for corrosion resistance. View our selection of Galvanized Steel Spiral Ducts.
* Stainless steel spiral ducting offers superior corrosion resistance – perfect for outdoor and chemical-exposed applications. While more expensive, it will resist corrosion longer than galvanized steel ducting. View AGI’s Stainless Steel Spiral Ducts product line.
* Paint grip spiral ductwork has a double-sided zinc coating for paint application. View our Paint Grip spiral ductwork inventory.
* Aluminum spiral ducts combine lightweight construction with high corrosion resistance. Check out AGI’s Aluminum Spiral Duct catalog.
* Polyvinyl-coated spiral ducting is a reliable substitute for traditional HVAC ducting in underground environments. Check out AGI’s Polyvinyl-coated spiral ducting selection.
Applications of Spiral and Oval Ductwork
A wide range of applications utilize spiral ductwork, including heating, ventilation, and air conditioning (HVAC) systems. In these systems, spiral or oval ducts efficiently circulate cooled or heated air, maintaining a constant and evenly distributed airflow within facilities.
Industrial ventilation systems frequently employ spiral ductwork to remove environmental toxins, such as chemical fumes and microbes, that can be hazardous to health. Additionally, dust collection systems use spiral duct pipes and fittings to remove particulate matter like industrial dust, wood shavings, and sawdust, preventing health issues, equipment damage, and fire hazards.
Bulk material handling systems also rely on spiral ducts to facilitate the transportation of various solids. Grain trucks, hoppers, and other material handling equipment use spiral ducts to efficiently move materials, streamlining the process and reducing the risk of accidents or material damage.
The versatility of oval and spiral ductwork also contributes to its popularity in a wide range of settings, including:
* Wood Catalogs: Oval and spiral ductwork is a practical choice for wood catalogs due to its durability and ability to withstand dust and debris.
* Agricultural Facilities: Our ductwork’s resistance to corrosion and pests makes it a suitable choice for agricultural facilities where chemicals and livestock are present.
* Industrial Manufacturing Plants and Warehouses: spiral and oval ductwork’s versatility and ability to handle high air pressure make it a common choice for industrial manufacturing plants and warehouses.
* Churches: spiral and oval ductwork’s aesthetic appeal and ability to blend in with existing architecture make it a suitable choice for churches and other places of worship.
* Restaurants: spiral and oval ductwork’s ability to handle grease and moisture-laden air makes it a practical choice for restaurants and other food service establishments.
* Offices and Educational Institutions: spiral and oval ductwork’s energy efficiency and quiet operation make it a popular choice for office & educational buildings.
* Medical Facilities: spiral and oval ductwork’s ability to maintain high indoor air quality and withstand extreme temperatures makes it a suitable choice for medical facilities.
* Retail Stores: spiral and oval ductwork’s aesthetic appeal and ability to blend in with existing architecture make it a popular choice for retail stores.
* Sports Facilities, Entertainment Venues and Community Centers: spiral and oval ductwork’s ability to handle large volumes of air and withstand corrosive environments makes it a common choice for entertainment venues.
