3 Essential Precautions for Using Sheet Metal Ducting

Posted on: 30 July 2018

Sheet metal piping is ideal for use in commercial and industrial HVAC systems. In general, this type of ducting is favoured over alternatives because it is highly durable, especially when compared to plastic and fibreboard alternatives. Also, the surfaces of the sheet metal ducts are smooth and do not promote the accumulation of dirt or growth of bacteria. However, you should note that the performance of sheet metal tubing in duct applications will depend on the installations choices. Here are simple tips to help in attaining the best results with your sheet metal ducting.

1. Choose the Best Piping

You should choose the best sheet metal ducts for your applications. Your selection will determine the ease of installation and the long-term performance of the tubing. The standard choice for most buildings is the round pipe. As implied, this tubing is circular, and it allows efficient flow of air. Rectangular pipes are also quite popular. Their shape makes them convenient for installation in areas with limited spaces such as in floors and beneath roofs.

You can combine the benefits of the round and rectangular pipes by choosing oval sheet ducts. Their flattened shape makes these tubes more ideal for placement in limited space. The roundish shape allows them to promote smooth airflow. Spiral pipes are similar to round pipes. However, their structure has a spiral design which promotes the flow of air with minimal noise production. Additionally, these are less prone to leaks.

2. Insulate the Ducts

You should insulate the sheet metal pipes after installation for optimal performance. The materials used in fabrication are good conductors of heat. Therefore, if the pipes are left bare, they will allow the flow of heat through the walls. This flow means that heated air will lose its temperature while cooled air will gain heat from the surroundings. With the right insulation, you will limit this exchange and promote optimal energy efficiency in your commercial or industrial building.

3. Seal the Channels

You should seal the sheet metal tubing during installation. In general, cracks will appear between two sections of piping. A small gap between the two lengths will cause significant leakage of air. As a result, efficiency will be compromised. You can prevent these losses by connecting the ductwork correctly. If possible, you should custom-fabricate the sheet metal piping to guarantee a close connection between the different sections.

Finally, you should plan on hiring an experienced contractor for the ductwork installation. The professional will lend their skills and knowledge, ensuring ideal ducting performance. For more information, contact your local pipework installation team.
