Abstract: A fracturing tube system for introducing into a borehole in order to carry out a hydraulic and/or pneumatic fracturing process, including a plurality of tube lines. 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 has at least one traction cable, multiple coupling devices which can be removably attached to the at least one traction cable, and multiple tube sections which are separate from one another and which can be coupled to the coupling devices in a pressure-tight manner and thus form the tube lines as a whole.

Abstract: A pipeline fitting, which comprises connection support elements and can be easily installed and removed, for indirectly connecting a first pipe connection to a second pipe connection. Compression joints between the first and second connection support elements of the pipeline fitting and a first and a second compression joint flange on a first and a second compression joint connector can be produced in the longitudinal direction of the pipeline fitting. This is achieved in that the pipeline fitting features a vibration compensator with an elastic bellows, as well as a respective tubular fitting section and a sealing ring integrally formed thereon to both sides of the bellows in the longitudinal direction, wherein the sealing ring can be clamped between a connecting flange of the connection support element and the compression joint flange of the compression joint connector.

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.
