     Introduction:

    Air flue rubber joint compensator is composed by rubber composite materials, steel flange, sleeve, thermal insulation materials. Mainly used in various fan, air duct for flexible connection. The function is shock absorption, noise reduction, sealing, medium resistance, facilitate displacement and installation, is the ideal pipe fitting for vibration reduction, noise reduction, eliminate smoke and dust in environmental protection field.
     
     

    Chemical resistance, temperature limitations, abrasion resistance, tensile strength and susceptibility to flutter/vibration are major considerations when selecting a flexible element fabric material. They are configured either as a flat-type or convex type. Materials include elastomers, fabrics, insulation materials and fluoroplastics, either constructed in a single layer or multiple layers.

    A variety of styles and materials are available to optimize the design to meet the specific requirements of any given application. Our application engineers combine different steel frame types and industry proven belt fabric materials and options. In some instances, additional components such as insulation pillows, accumulation barriers or flow liners are used to help protect the fabric material. The basics are shown below, but a number of other design elements are possible. Also of interest may be our fully molded rubber duct expanion jonts, which can provide additional movements and ease of installation for flanged applications.

    • Relative light weight

    • Non-conductive

    • Abrasion and corrosion resistant

    • High fatigue resistance

    • Wide material selection

    • Movement achieved with relatively low force
