BEST-IN-CLASS VIBRATION ABSORBERS Belman has developed a series of Vibration Absorbers, which are designed for versatile usage in any system where pump vibrations occur. The standard range is made from multi-ply bellows with several very thin layers of stainless steel. This delivers maximum performance regarding: pressure and temperature bearing capacity, noise and vibration absorption and overall cyclic service life. They have a standard overall length of 130 mm for the easy replacement of any Rubber Expansion Joint. The range of Vibration Absorbers can resolve any problems related to mechanical vibration and have a higher pressure and temperature capacity than rubber bellows. Unlike Rubber Expansion Joints, stainless steel bellows do not suffer from atmospheric damage when used in an outdoor installation. Design range within Vibration Absorbers Belman Vibration Absorbers can be designed within Belmans design range: DIMENSIONS: DN 15-12.000 PRESSURE: Up to 150 Barg (2176 psi) TEMPERATURE: -256°C to +1000°C MATERIALS: Austenitic stainless steels, High alloys, Duplex, Titanium, Hastelloy, Incoloy, Inconel, Alloy 59 DESIGN CODES: EN 13445, EN 13480, EN 14917 ASME VIII, div.I, ASME B31.3 ASME B31.1, EJMA and others on request TESTS: Radiographic examination (X-ray), Helium leak testing, Pressure test, Air test, Dye penetrant test, Magnetic particle examination and many more VIBRATION ABSORBERS PRODUCT RANGE VIBRATION ABSORBERS with WELDED FLANGES VI1FT / ID no. 90 DN 50 – 300 PN 16 Product sheet (PDF) CUSTOMISED VIBRATION ABSORBERS Belman expertly engineer customised Vibration Absorber solutions Request Customised VIBRATION ABSORBERS VIBRATION ABSORBERS TECHNICAL DESCRIPTION APPLICATIONS In pipe systems and installations where vibrations and stresses occur Pumps, compressors, engines, burners etc. House installations, industrial installations etc. Heating, climate, ventilation and heat recovery installations Gas, water and sewage treatment plants CONSTRUCTION AND DESIGN The Vibration Absorbers feature rubber bushes for the tie rods for maximum noise and vibration reduction. They can withstand high pressure at elevated temperatures, with flat steel springs holding the tie rods. The tie rods ensure that pressure thrust forces from the pump are not transferred to the adjacent pipe system. Compensate for installation misalignments between pipe systems and pumps, and thermal growth Eliminates pressure thrust forces and torques on pumps and other equipment Reduces vibrations, oscillations, and noise (sound and vibration) from pumps into pipe systems The multi-ply bellow ensures maximum performance regarding pressure, temperature and service life Standard design is: 16 BarG, and overall length of 130 mm for easy replacement of rubber bellows Special designs are available to any specification ADVANTAGES Vibration Absorbers represents several advantages for the piping designers. Advantages What are the advantages of using Vibration Absorbers? Unlike Rubber Expansion Joints, the vibration absorbers are resistant against ageing, high temperatures and UV-radiation Reduction of long-term operation and maintenance costs Increased reliability and prolongation of the service life of the pipe system and connected equipment Tie rods as standard for minimum fixation of pipe system (available without tie rods, on request) VIBRATION ABSORBERS INFORMATION & TOOLS To ease the work with Expansion Joints for everyone being involved with Expansion Joints Belman provides here useful Engineering tools and further technical information.
