A pipe section of a common rail line is provided for the high-pressure injection of a fluid. The pipe section has at least a first pipe and an adapter in which the first pipe has a wall and extends at least along an axial direction. The wall has an inner circumferential surface and an outer circumferential surface and encloses a first line. The adapter has a connector piece and a second pipe. The connector piece extends annularly around the first pipe and is situated on the outer circumferential surface. A second line that is formed by the second pipe is fluidically connected to the first line via a first opening in the first pipe and a second opening in the connector piece. At least the adapter is manufactured by a metal powder injection molding process. Two methods for manufacturing a pipe section are also provided.

The present invention relates to a method of manufacturing a pipe, which method comprises cold-gas dynamic spraying of particles onto a suitable support member thereby producing a pipe, and separating the pipe from the support member.
