.jpg) | Expansion Joints - Duct Rubber Flue 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. Is capable of handling any combination of large movements which might occur in a ducting system due to thermal expansion. 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 as well as white FDA food grade elastomers. Let us assist you in selecting the right product for your application. Configurations: • Square, rectangular or round in any size. Standard construction "U" shape, 9" face- to-face, 3" flange. • Arch shapes also available. One piece body 5/16" thick. Steel retaining rings are provided (send drawing or call us for quotation.) Choice of Material: Fabric Reinforcement: Joints may be constructed of *Nomex (to 400 ◦F), fiberglass or polyester cloth impregnated with one of the following: Tube and Cover Neoprene–Resistant to heat, adverse weather, ozone and fuel gasses. Impervious to fats, oils, greases and other petroleum products. For use up to 250◦F. Chlorobutyl–An elastomer with all of the above advantages of neoprene, with the exception of its inability to withstand oil. For use up to 300◦F. *Viton®/**Fluorel® –In addition to providing all of the properties of neoprene, Fluorel is resistant to mineral acids and usable in 400 applications.. Silicone–A high-quality elastomer recommended for all environments except those with sulfur gas. For use in -70◦F to 500◦F applications.

.jpg) | Expansion Joint - HIGH TEMPERATURE FLUE DUCT JOINTS (Fabric) • Available in "U", belt, square, round or rectangular configurations. • More movement in a shorter space than metal joints. • Less reaction force for pipe movement. • No vibration fatigue or high cycling failure. • Light weight and easy to install. • A wide range of composite materials available to meet temperature and corrosion resistance requirements. • Temperature capabilities to 2000º F. • Baffle and insulation pillow designs available. Service Features of Fabric Expansion Joints: • Absorb axial, transverse and torsional movements • Corrosion and chemical resistance • Negligible spring rates and loads • Easily repairable and installable • High cycle life • Unique application solutions • Vibration dampening and sound attenuation • More movement in shorter face-to-face • Less force to flex than metal expansion joints • Excellent corrosion and chemical resistance • Temperature capability range (-110°F to more than 2,000°F) • Lower shipping and installation costs • Variety of flexible belt materials available: • Single-layer and composite belts • Elastomers have excellent abrasion resistance • Custom designed for each specific application Design Considerations Media: Internal and External Environment Temperature: Constant operating and maximum excursion Pressure: Normal positive or negative Movements: Axial and lateral, simultaneously or independently Installation: Existing equipment and duct flanges Assembly: Factory-assembled or field-spliced Baffles Baffles are usually not necessary with elastomeric expansion joints due to the tube resistance to most abrasive particular matter. However, baffles must be used with fabric composite joints to protect the inner surface form particulates in the gas stream. We can supply baffles fabricated from carbon steel, stainless steel, or other materials as required. Retaining Rings Standard construction calls for 2" wide, 3/8" thick bars with slotted holes for easy installation. Material of construction can be carbon steel, corten or stainless steel. Availability • U-type • Belt type • Square • Rectangular or round • No size restriction • Choice of FF dimension, depending on movements • Associated Metal Work: Backup bars, frames, flanges and baffles Additional Info: http://www.global-hose.com/expansion-joints-metal-hoses | ||||||||
