  • Device for rapidly cooling metal tubes
    Patent number: 4373703
    Abstract: The device according to the present invention is an improvement on the conventional devices for quenching metal tubes (3) by immersion into a tank (4) of liquid at ambient temperature.This device comprises in particular a deflector (18) positioned below the tube at the time of its immersion. This deflector distributes the contact of the cooling fluid on the surface of the tube (3). It allows a more homogeneous cooling and avoids asymmetric deformations of the tube (3). An air injection system fastened to the end of the tube to be treated is associated with this deflector.This device will be particularly useful in installations for treating very long, thin tubes.
