Heavy Wall Bellows . Edition 8. Bellow Design Guide - Free download as Word Doc (. nl Truco rubber bellows are also used to compensate for axial, lateral and angular movement in a pipework system and are available ex-stock in 3 different polymers, namely EPDM, chloroprene and butyl from 40nb to 600nb. Since the best design is a compromise, or balance, between pressure strength and flexibility considerations, it can be concluded that their designs have had lower margins of safety regarding fatigue than they had regarding pressure strength. Rubber Bellows General Our rubber bellows are made from various elastomers and provide the flexible element in pipe Rubber Design B. The ARPM rubber handbook provides standardized drawing designations for specific design requirements of molded rubber products. The information set forth is based upon the substantial experience in research, design and application Of rubber joints by engineering personnel associated with the member companies of the Expansion Joints-Piping cannot be handled by conventional computer-aided design (CAD) softwares. We design, develop and deliver customized silicone rubber bellows that effectively and efficiently protect your valuable equipment from dust, water, some grease, some acids, bleaches, and splatter. An inner liner of calendered rubber. It outlines 11 key design parameters to consider, such as type of flexing required, stroke length, pressure ratings, temperature ranges, and joining method. We, at Auroflex have now established ourselves as a trusted supplier We can custom make to order Rubber Bellows from your professional CAD drawings to hand sketches (see example below). Molded rubber bellows are similar to expansion joints and convoluted tubing but have a larger extended-to-retracted ratio for tighter compression and a more dynamic range of motion.
