bautz klinkhammer rubber vibration isolator, Germany bautz klinkhammer model, bautz klinkhammer price

bautz klinkhammer rubber vibration isolators consist 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 consists of multiple layers of high-strength fiber or steel strip (wire) reinforced interlayers. The reinforced interlayers, such as reinforcing fibers or steel strips (wires), extend all the way to the rubber flanges at both ends, which contain a hard steel wire skeleton. Rubber expansion joints have large displacement compensation capabilities, allowing for axial, lateral, and angular displacement compensation, reducing noise, minimizing vibrations, and providing some corrosion resistance. They feature high pressure resistance, good elasticity, large displacement capacity, effective vibration absorption and noise reduction, and easy installation, making them widely applicable in water supply and drainage, HVAC, fire protection, compressors, papermaking, pharmaceuticals, shipbuilding, pumps, fans, and other piping systems.

bautz klinkhammer rubber vibration isolator selection

Selection instructions for flexible rubber joints: 1. The standard applicable temperature range for rubber joints is -200 to 70°C. The instantaneous temperature can reach 115°C, and the operating temperature is 70 to 115°C. 2. For flange-connected rubber joints, if the working pressure and temperature are high (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 to both ends of the flange, with washers or spring washers added, and the bolts must be tightened 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.

bautz klinkhammer 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 welding, and clamp-shell types. Among them, bellows expansion joints are the most widely used, while ring plate welding expansion joints are only suitable for atmospheric or low-pressure applications.

bautz klinkhammer rubber vibration isolator applications

Expansion joints are also commonly referred to as compensators or telescopic joints. They consist of a bellows (an elastic element) forming the main working body, along with end pipes, supports, flanges, conduits, and other accessories. Expansion joints are flexible structures installed on container shells or pipelines to compensate for additional stresses caused by temperature differences and mechanical vibrations. By utilizing the effective telescopic deformation of the bellows, they absorb dimensional changes in pipelines, conduits, containers, etc., due to thermal expansion and contraction, or compensate for axial, lateral, and angular displacements. They can also be used for noise reduction and vibration damping, particularly in heating systems. To prevent pipeline deformation or damage caused by thermal elongation or temperature stress when heating pipelines expand, compensators need to be installed to compensate for the thermal elongation of the pipeline, thereby reducing stress on the pipe wall and forces acting on valve components or support structures. As an elastic compensation element capable of free telescopic movement, expansion joints offer reliable operation, excellent performance, and compact structure, making them widely used in chemical, metallurgical, nuclear energy, and other industries. Various forms of expansion joints are used on containers; regarding the shape of the bellows, U shaped expansion joints are most widely applied, followed by Ω-shaped and C shaped types. For pipeline applications, expansion joints are classified based on structural compensation into universal type, pressure balanced type, hinged type, and universal joint type.
