Duct work

Short Introduction

What is Ductwork? Ductwork refers to a system of ducts and vents designed to circulate heated or cooled air throughout a building. It plays a vital role in a building’s heating, ventilation, and air conditioning (HVAC) system. Ductwork is primarily categorized into four main types, which are as follows:

  • Air Conditioning Ductwork
  • Exhaust Ductwork
  • Ventilation or Fresh Air Ductwork
  • Flare Lines, Chimneys, and more

Types of Ducts:

  • Square or Rectangular Ducts
  • Spiral or Oval Ducts
  • FRP Ducts
  • Aluminum Flexible Insulated Ducts and more

Ductwork can be further categorized based on design, shapes, material selection, and the primary purpose behind choosing a specific form to achieve optimal results. Let’s embark on our learning journey together as we delve into detailed discussions on various topics, one by one.

AIR-CONDITIONING DUCT WORK

What is Air Conditioning Duct Work? Air conditioning duct work consists of the network of ducts, vents, and fittings responsible for distributing cooled or heated air throughout a building. This ducting system is essential to an air conditioning setup, ensuring that air is evenly circulated within the space. Typically, galvanized iron (G.I.) sheets are the most widely used material for ducts, with thicknesses ranging from 20g to 26g, depending on specific needs and budget constraints.

EXHAUST DUCT WORK

What is Exhaust Ducting? Exhaust ducting is the system of ducts and vents designed to expel stale or contaminated air from a building to the outdoors. It plays a vital role in a building’s ventilation system by eliminating pollutants, moisture, and heat. Exhaust ducting is essential for commercial and industrial environments, as it effectively removes polluted and hazardous air.

FLARE LINES OR CHIMNEYS

What is a Flare Line or Chimney? A flare line, also known as a chimney, is a venting system utilized in air conditioning, refrigeration, and heating applications. Its primary function is to safely expel flammable gases, like refrigerants, and other combustion byproducts into the outside atmosphere. Chimneys are essential for industrial facilities with production or manufacturing operations. Their main purpose is to remove hazardous and flammable gases from production plants, furnaces, or boilers, allowing them to be released into the atmosphere after proper treatment. The pathway that transports these gases from beginning to end is commonly referred to as "Flare Lines" or "Chimney".

FLEXIBLE DUCT WORK

What is Aluminum Flexible Duct? Aluminum flexible duct refers to a type of ducting made from aluminum, a lightweight and corrosion-resistant material. It is specifically designed to create a flexible and durable connection within an HVAC system, such as linking a vent to a duct. Additionally, aluminum ducting is often paired with thermal insulation, eliminating the need for additional thermal protection.

FRP DUCT WORK

What is FRP Ducting? FRP ducting refers to a type of ductwork created from fiberreinforced polymer (FRP), a composite material that combines fibers, such as glass or carbon, within a polymer matrix. It is utilized across various sectors, including HVAC, chemical processing, and wastewater treatment. FRP ducts are typically employed in corrosive environments where traditional sheet metal ducts can rust within a certain timeframe. The insulation of FRP ducts boasts superior thermal properties compared to sheet metal duct nitrile rubbers, with thicknesses ranging from 6mm to 32mm, depending on specific thermal control needs.

RECTANGULAR DUCT WORK

What is Rectangular Ducting? Rectangular ducting refers to a specific type of ductwork utilized in heating, ventilation, and air conditioning (HVAC) systems for air distribution throughout a building. Its defining feature is its rectangular shape, which offers a greater surface area for airflow compared to round ducts. In the HVAC industry, rectangular ducts are the most prevalent and cost-effective option.

SPIRAL OR OVEL DUCT WORK

What is Spiral Ducting? Spiral ducting refers to a specific type of ductwork utilized in heating, ventilation, and air conditioning (HVAC) systems for air distribution throughout a building. Its distinctive spiral or helical design ensures a smooth and efficient airflow path. Spiral ducts are typically employed in areas with exposed ceilings, offering an aesthetically pleasing option that blends seamlessly with interior designs. Although spiral ducts tend to be more expensive than rectangular ducts, they necessitate specialized duct fabrication machinery, such as lock formers.

VENTILATION “OR” FRESH AIR DUCT WORK

What is Ventilation Ducting? Ventilation ducting encompasses the system of ducts, vents, and fittings that facilitate a controlled air flow in and out of a building. It plays a vital role in a building’s ventilation system by removing stale air, moisture, and pollutants while introducing fresh air.
