Rectangular plastic duct is a popular choice for ventilation and air distribution systems because of its durability, affordability, and ease of installation. PP/PVC plastic air duct has strong corrosion resistance and is widely used in the field of chemical production. In this article, we will guide you through the installation process of rectangular plastic air duct. We’ll cover basic topics such as joining plastic pipe, cutting rigid plastic pipe, calculating rectangular pipe to circular, and understanding the different sizes of rectangular Plastic Duct.
How to connect plastic pipes?
Joining the plastic duct is a simple process that ensures a secure and airtight joint for optimal airflow. Here is a step-by-step guide to help you connect plastic pipe effectively:
Gather the necessary materials: You will need plastic duct connectors, aluminum foil tape, and a box knife.
Measure and mark the ducts: Using a tape measure, mark the pipes where the connections will be made. Make sure the marks are aligned correctly for a proper fit.
Cutting the duct: Use a utility knife to cut along the marked line on the pipe. Make sure the cuts are clean and precise.
Insert Connector: Insert the plastic duct connector into the cut end of the pipe. Push them in firmly until they are snug.
To secure the connection: Wrap the joint with aluminum foil tape, making sure it covers the entire circumference of the connection. This step will make the connection more airtight and prevent any air leaks.
Repeat the process: Follow the same steps for connecting any additional pipes, making sure each connection is properly sealed.
How to cut rigid plastic duct?
Accurate cutting of rigid plastic duct is critical to achieving the lengths required for ventilation systems. Here’s how to effectively cut hard plastic duct:
Measure and Mark duct: Measure the length you need and mark the pipe using a tape measure and pencil. Make sure the markings are clearly visible.
Prepare the cutting area: Set up a stable cutting surface, such as a workbench or sawhorse. Place a piece of scrap wood under the area to be cut to prevent damage to the underlying surface.
Choose the right tool: For cutting hard plastic duct, a fine-toothed hand saw or jigsaw with a fine-toothed blade works well. Make sure the blade is specifically designed for cutting plastic.
Cut along the marked line: Place the pipe firmly on the cutting surface and carefully cut along the marked line with the saw. Apply steady, even pressure to ensure smooth and precise cuts.
Remove any burrs: After cutting, use sandpaper or a file to smooth any rough edges or burrs on the cut end of the pipe.
How do you calculate rectangular plastic duct to circular?
Occasionally, you may need to convert rectangular ducting to circular for compatibility with certain ventilation components. To calculate the equivalent circular size for rectangular ducts, use the following formula:
Circle diameter = (1.30 × √(height × width)) / 2
In this formula, “height” refers to the longer side of the rectangular duct, and “width” refers to the shorter side. The result will give you the diameter of the equivalent circular pipe.
What are the dimensions of the rectangular plastic duct?
Rectangular plastic ducts are available in a variety of sizes to suit different airflow requirements. The dimensions of a rectangular plastic duct are usually specified by its height and width dimensions. Common sizes range from 3″ x 10″ (3″ x 10″) to 24″ x 36″ (24″ x 36″). However, you must consult your local building codes, HVAC professional or product specification for the most suitable size
