febrotec rubber vibration isolator Germany febrotec model febrotec price

febrotec rubber vibration isolator consists of a smooth bellows compensation element with rubber flanges at both ends and metal flanges. The metal flanges often adopt a loose sleeve structure. The surface of the bellows compensation element is rubber, and the inner layer is a multi-layer reinforced interlayer of high-strength fiber or steel strip (wire). The reinforced interlayer, such as reinforced fiber or steel strip (wire), extends to the rubber flanges at both ends, which contain a hard steel wire skeleton. The rubber expansion joint has large displacement compensation capability, can compensate for axial, lateral and angular displacements, and has the ability to reduce noise, reduce vibration and certain corrosion resistance. It features high pressure resistance, good elasticity, large displacement, effective vibration absorption and noise reduction, and easy installation. It is widely used in pipeline systems for water supply and drainage, HVAC, fire protection, compressors, papermaking, pharmaceuticals, ships, water pumps, fans, etc.

febrotec rubber vibration isolator selection

Selection instructions for flexible rubber joints: 1. The standard applicable temperature range for rubber joints is -200 to 70°C. Instantaneous temperature can reach 115°C, and operating temperature is 70 to 115°C. 2. For flange-connected rubber joints, under higher working pressure and working temperature conditions (nominal diameter above 200, temperature above 70°C, working pressure above 1.5Mpa), flange rubber joints equipped with limit devices can be selected. 3. For flange-connected rubber joints, during installation, the bolts connecting the flanges must be inserted from the inside of the flange towards both ends of the flange. Use gaskets or spring washers, and tighten the bolts diagonally and gradually. For rubber joints connected with union joints, do not swap the union joints at the left and right ends during installation to avoid product leakage or damage.

febrotec rubber vibration isolator advantages

It is a flexible element that can effectively compensate for axial deformation. For example, expansion joints welded to the shell of fixed tube-sheet heat exchangers have high axial flexibility and are prone to deformation. They can compensate for the thermal expansion difference between tubes and shells caused by different wall temperatures, reduce their axial loads, thereby reducing the temperature differential stress on tubes, tube sheets and shells, avoiding strength failure, instability failure and tube pull-out failure. There are many types of expansion joints, commonly used structures include bellows, ring plate welded and clamp-shell types, among which bellows expansion joints are the most widely applied. Ring plate welded expansion joints are only suitable for atmospheric or low-pressure occasions.

febrotec rubber vibration isolator applications

Expansion joints are also commonly referred to as compensators or expansion loops. They consist of a bellows (an elastic element) that forms the main working body, along with accessories such as end pipes, supports, flanges, and guide tubes. An expansion joint is a flexible structure installed on vessel shells or pipelines to compensate for additional stresses caused by temperature differences and mechanical vibrations. It utilizes the effective axial deformation of its main working bellows to absorb dimensional changes in pipelines, guide tubes, vessels, etc., due to thermal expansion and contraction, or to compensate for axial, lateral, and angular displacements in pipelines, guide tubes, vessels, etc. It can also be used for noise reduction and vibration damping. In heating systems, to prevent pipeline deformation or damage caused by thermal elongation or temperature stress when the heating pipeline heats up, compensators need to be installed on the pipeline to compensate for the thermal elongation of the pipeline, thereby reducing the stress on the pipe wall and the forces acting on valve components or support structures. As an elastic compensation element capable of free U and C, expansion joints offer advantages such as reliable operation, good performance, and compact structure, and have been widely used in industries such as chemical, metallurgical, and nuclear energy. There are various types of expansion joints used on vessels. In terms of bellows shape, U-shaped expansion joints are the most widely used, followed by Ω-shaped and C-shaped ones. For pipelines, expansion joints are classified based on structural compensation into universal type, pressure-balanced type, hinged type, and universal joint type.
