1. A pipe arrangement comprising:
a pipe having a circumferential burr at an inner circumferential edge of an end of the pipe; and
a connecting element having a base body with a through channel, the base body having a receiving bore receiving the pipe end of the pipe, wherein the receiving bore corresponds with the through channel, wherein the receiving bore has a larger cross section than the through channel, and wherein a transition step is formed in the base body between the through channel and the receiving bore,
wherein the transition step has a radial section and an axial section, and wherein a transition between radial section and axial section is rounded to form a curvature extending in the axial direction, and
wherein the axial section of the transition step is sized and positioned such that it receives the circumferential burr of the pipe.
