Abstract

This disclosure relates to a device in the form of a connecting pipe for use in heat pump devices for decoupling as well as for vibration control. The device includes a pipe section as well as a connecting element arranged at each end. The device further includes two non-metallic, spaced, staggered bellows assemblies for vibration compensation, the pipe section having a constant material thickness between the connecting elements, apart from any individual stabilizing rings. In addition, the bellows arrangements includes of one or more annularly closed foldings, each extending 360°.

Abstract

The invention relates to a device (2) in the form of a connecting pipe for use in heat pump means for decoupling and for vibration control, comprising a pipe section (R) and in each case one connector element arranged on the end side. The device (2) comprises precisely two non-metallic gaiter arrangements (F), which are spaced apart and arranged offset, for vibration compensation, wherein the pipe section (R) has a constant material thickness between the connector elements, apart from possible individual stabilizing rings (15). In addition, the gaiter arrangements (F) consist of one or more annularly closed folds which in each case run around by 360°.

Abstract

The invention relates to a fracturing tube system (1) for introducing into a borehole in order to carry out a hydraulic and/or pneumatic fracturing process, comprising a plurality of tube lines (10). The fracturing tube system is to be designed such that it can be produced in a simpler and more economical manner and such that a variable total length of the fracturing tube system can be introduced into a borehole with little effort. This is achieved in that the fracturing tube system (1) comprises at least one traction cable (11), multiple coupling devices (12) which can be removably attached to the at least one traction cable (11), and multiple tube sections (100) which are separate from one another and which can be coupled to the coupling devices (12) in a pressure-tight manner and thus form the tube lines (10) as a whole. A pressure-tight releasable connection of the tube sections (100) to feedthroughs (120) of the coupling device (12) can be achieved so that fluid can be conducted from one tube section (100) into a subsequent tube section (100) through the feedthrough in the coupling device (12) in a tube-free manner.
