Flue ducting expansion joints are used in various industries and applications such as power generating facilities, pulp and paper mills, steel mills and chemical plans. The main reason for using these joints is to relieve stresses in piping and ducting systems caused by thermal expansion and contraction. Elastomeric strip seal expansion joints are often used flue ducting system as they are durable and flexible expansion system. Viton expansion joints are made using high-performance fluorocarbon-based elastomer known as Viton and are ideal for applications involving aggressive chemicals, high temperatures, and severe operating conditions. Here are some of the features and uses of these expansion joints

·         Adding flexibility

·         Absorbing thermal growth

·         Isolating vibration and noise

·         Accommodating misalignment in industrial ducting systems

These expansion joints are made using fabric/belt type material and may also sometimes feature fully integrated flanges.  These expansion joints are typically made for use in lower pressure gaseous service where there may be a presence of high temperatures and are uniquely molded to your application needs using industry-proven elastomers and fabric reinforcement materials

While it is important to consider resiliency, durability and maintained, it is equally important to understand operating conditions, temperatures and pressures in the ducting system.

Choosing the right flue duct expansion joint

If you are looking to choose the appropriate flue duct expansion joint, it is recommended to consider the following parameters:

·         Temperature

·         Movement

·         Media (wet and or/dry)

·         Chemical compatibility of gas and particulate

·         Environmental exposure

·         External environment

·         Safety and/or any regulatory requirements

These expansion joints are typically custom designed to manage thermal expansion, stress relief conditions and other aspects as required. As there is a vast array of materials available, these joints can be designed to meet any thermal, chemical, or environmental demands of diverse systems, equipment, and processes
