In order to sustainably cover the ever-increasing global energy demand, gas fields are tapped in more and more remote areas. From there, the gas extracted is either transported via pipelines, or in liquefied form, by means of tankers via sea routes directly to the customers or to processing facilities. In both cases, powerful gas compressors are used before the transport takes place. Torsionally rigid, non-switching steel disk couplings of the RINGFEDER® TND series are ideally suited for establishing a stable and reliable drive connection between the motor and compressor, since they fully comply with typical requirements. They are manufactured of 100 % stainless spring steel, highly resistant to extreme temperatures and ensure maximum transmissible torques while providing the ability to compensate axial, radial and angular misalignments. Furthermore, they do not require lubrication and therefore work in a maintenance-free and almost wear-free fashion. Depending on the specific requirement, RINGFEDER® intensively assists its customers in finding the ideal mounting type of the shaft and hub, e.g. via first-class shrink discs or locking assemblies.
In intensive cooperation with a globally leading manufacturer of drilling systems and drilling components, which are predominately used in the field of deep drilling for the extraction of crude oil and natural gas storage facilities, RINGFEDER® has implemented a tailor-made special solution. Depending on the performance of the drilling tools used, they potentially get stuck in the subsurface if its condition exceeds a certain degree of hardness or softness. In order to release such a blockage again, a pneumatically driven internal hammer drill works against the drilling tool. A RINGFEDER® friction spring specially designed for this purpose serves as a high-performance damping element which effectively absorbs thrusts and, in this way, reliably protects the drilling tool against tremendously costly damage and failures – and it is absolutely maintenance- and repair-free.
