A pipe component has a casing embodied as a folded bellows with folds. A tubular support body has an outer circumference and a length extension in a direction of a center line of the tubular support body. The tubular support body is embedded in the casing and supports the casing. The tubular support body has at least one stabilization element and the at least one stabilization element has segments that are axially spaced apart and at least partially extend circumferentially. The segments are connected by one or a plurality of hinges, respectively, along the length extension of the tubular support body. The hinges are arranged in the folds of the folded bellows of the casing.

A hose arrangement for a motor vehicle may include a flexible elongated bellows including a plurality of radially orientated pleats and two axial longitudinal ends. The hose arrangement may also include at least one reinforcement rib which, on an outside, is coupled to a pleat tip of a respective pleat of the plurality of pleats in a material-bonded manner via two-component injection moulding. The at least one reinforcement rib may engage about the respective pleat in a circumferential direction. The at least one reinforcement rib may have at least two rib segments disposed following one another in the circumferential direction. Each of the at least two rib segments may radially cover the pleat tip by a segment angle of 30° to 310° in the circumferential direction.

A high-pressure fluid line including a corrugated tube defining a fluid flow channel its interior, wherein a wall of the corrugated tube, in parallel with the extension direction of the fluid flow channel, comprises a sequence of wave peaks and wave troughs. The fluid line includes a braiding made of threads, which is applied to an outer periphery of the corrugated tube. The braiding bears tightly against the outer periphery of the corrugated tube at a substantially constant braiding angle over the entire corrugated tube. The braiding and the corrugated tube are connected at least at two mutually separate locations such that stretching of the corrugated tube in a longitudinal direction is accompanied by a reduction in a diameter of the braiding.
