Expansion Joints #4949395

UNAFLEX "MIGHTY-SPAN" Style 600 Rubber Flue Duct Expansion Joints are designed to handle hot air or gasses in industrial duct work, as well as those generated by power plant and pollution control equipment. They are custom constructed of rubber and fabric to absorb thermal movements and vibration in duct work and to aid in the elimination of noises caused by scrubber equipment and mechanical dust collectors. MIGHTY-SPAN is capable of handling any combination of large movements which might occur in a ducting system due to thermal expansion. MIGHTY-SPAN creates almost no load on damper and fan interfacing flanges, thus providing much needed protection in these critical areas. A wide range of elastomers and fabric substrates are available to provide maximum resistance to corrosion and high temperature capabilities. Let UNAFLEX assist you in selecting the MIGHTY-SPAN product for your application. Available in a wide choice of materials and Drill Patterns

UNAFLEX can custom design and manufacture various types of expansion joints based on your needs and requirements of the system. Some commonly used non-standard expansion joint types are: Dual Expansion Joints Drilling Information Dual expansion joints are used where axial movement is larger than can be absorbed by a single expansion joint. The dual assembly consists of two single bellows connected by an interconnecting weld end. In some cases, this interconnecting weld end has an integral anchor base. The anchor base is designed to withstand the forces required to move either bellows but not for pressure forces. When no anchor base is used, interconnecting weld end must be anchored with standard pipe anchors. Dual expansion joints can also be used where large amount of movement in any combination (i.e. axial, lateral and angular rotation) is required which cannot be absorbed by a single expansion joint. In this type of application, the interconnecting weld end is not anchored but the remaining system must be properly anchored and guided. back to top of page

ThermaFlex Fabric Expansion Joints are non-metallic flue duct expansion joints that provide stress relief for piping and ducting systems by absorbing thermal growth and shock, isolating mechanical vibration, and allowing for misalignments.ThermaFlex expansion joints are precision engineered specifically for your application. ThermaFlex Flue duct expansion jointsare custom engineered to handle low pressure (3 psig) applications with temperatures ranging from -100F to more than 2000F. Industry Proven materials and precise engineering go into every Thermaflex Fabric Expansion joint. UNAFLEX is the country's leading Expansion Joint Manufacturer.
