How do HVAC Expansion Joints Work?
18 Jun 2020 Industrial Dampers
In any HVAC application, there is usually a complex interworking system of expansion joints to ensure that the unit has compensation for vibrations, pressure, and movement. The right flexible expansion joints can help to extend the life of any HVAC system by a large margin. If you are putting together a new HVAC system, it is important to know how different HVAC expansion joints work in order to ensure that you get the best products for your needs. The engineers at Flextech Industries design and manufacture a variety of piping and HVAC products that are designed to improve efficiency and performance for all kinds of implementations.
How Expansion Joints in HVAC Work
In order to offer flexibility and durability of an internal HVAC system, expansion joints and flexible hoses are often employed to allow the system to be more forgiving of expanding pressure and system movement. Some of the different types of HVAC expansion joints include:
If your HVAC system works with small pipe diameters that could suffer from thermal expansion, expansion compensators can help to prevent issues from arising. These joints utilize an externally pressurized bellows system that comes in various sizes for differing system requirements. The sleeve telescopes over the pipe to allow the pipe to extend without losing pressure.
Single- and Double-Sphere Rubber Connectors
Different types of rubber, including neoprene, EPDM, and buna nitrile, are often used to make these rubber connectors in order to provide a wide array of HVAC applications. Rubber HVAC connectors provide excellent shock and movement absorption in demanding applications.
Various Flexible Hose Connectors
Flexible hose configurations are often used in applications where movement is required to compensate for various factors, including seismic motion. Strong flexible hoses using metal braided exteriors are also frequently used in HVAC applications that require the ends to be offset. Flexible hoses can be used in conjunction to create U-Flex and V-Flex loop connectors, which are frequently used in situations with offset fittings or to provide the capacity for limited motion along an axis.
