The model TNZ ZCAF is composed from the coupling halves of the coupling TNZ ZCA and is complemented by an intermediate shaft and two rigid counter-flanges. If required, the torsional stiffness of the shaft can be tuned to the dynamic behavior of the drive line. In addition, the intermediate shaft, which serves to accommodate longer shaft separations, can be mounted and dismounted radially without having to move the connected machines. TNZ ZCBF: Double engagement design with a bolt-on O-ring carrier for ease of installation, and an intermediate shaft to fulfill specific requirements in terms of torsion spring stiffnesses The model TNZ ZCBF is composed from the coupling halves of the coupling TNZ ZCB and is complemented by an intermediate shaft and two rigid counter-flanges. If required, the torsional stiffness of the shaft can be tuned to the dynamic behavior of the drive line. In addition, the intermediate shaft, which serves to accommodate longer shaft separations, can be mounted and

During the construction of an industrial facility, much attention is paid to the strength of the service pipelines fasteners. It is also necessary to provide reliable connection of all units of industrial equipment with the pipelines. In this case, it is not always possible The use of a permanent welded joint is not always possible, therefore, there are various types of weld-free tight joints. FLANGE JOINT COMPONENTS At present, one of the most effective connections used in industrial facilities is a flange joint. This is an airtight connection that provides high structural integrity, consists of two flanges, fasteners (studs or bolts, washers, nuts) and gaskets. An important matter in choosing a set of flanges is tightness. The gasket material must have good elasticity, strength, resistance to the operating temperature conditions and to the media with which direct contact is expected. For flange joints, Villina company uses the following types

Fabric compensators are highly flexible and usually made of multi-ply fabric, offering excellent temperature resistance and chemical resistance depending on the particular design. Mainly used in pipe and conduit systems to compensate for axial, lateral and angular movements. One major advantage of this type of compensator is the low restoring forces. Special fabric materials permit temperatures of up to 1,000°C. Additional insulation can be used to resist temperatures of up to 1,600°C . Applications: Chemical plants, refineries, metallurgical industry, ventilation systems, chimney construction, industrial furnace construction, power stations, boiler systems, waste incineration plants, acoustic decoupling. Materials: Kevlar, fibre glass, glass needle felt, stone mineral wool mats, ceramic fabric, ceramic fibre mats, silicate felt mats, silicate fabric, Teflon Connection types: Continuous screws and screwed counter flange, clamping bars, tensioning belts straps
