Abstract

A cooling pipe arrangement (1) includes a pipe portion (2) in which two gripping elements (3) are arranged, with a coil spring (6) gripped between the gripping elements (3). The coil spring is surrounded by an annular space (15) into which opens a duct (16) for the coolant. The fluid which is supplied by way of the duct is conducted through the gap (19) between the turns of the coil spring, on to the rolled material which is conveyed through the cooling pipe arrangement. The width of the gap (19) may be varied by means of a setting ring (22).
