1. A cooling device (1) for cooling a seamless, rolled metal pipe (R), comprising:
a nozzle assembly (10) comprising one or more nozzles (14), which are configured to apply a cooling medium (K) to an outer circumferential surface of the pipe (R) while the pipe (R) is transported along a conveying direction (F) through a cooling section of the cooling device (1),
wherein the cooling device (1) is arranged immediately downstream of a rolling mill for rolling the pipe (R), such that the pipe (R) enters the cooling section while it is still engaged in the rolling mill with its rear end, and
wherein the nozzle assembly (10) has an access (Z) formed by a gap that is larger than a diameter of the pipe (R) and unobstructed along the conveying direction (F), and
wherein the pipe (R) can be removed from the cooling section in a radial direction of the pipe (R) and perpendicular to a longitudinal extension of the pipe (R) through the access (Z) after the rear end of the pipe (R) has exited the rolling mill.
