A shell tube and heat exchanger (10) includes a plurality of tubes surrounded by a shell (16). Each tube (12) includes a plurality of indentations. A mold is placed in a desired positions and orientation in a die. A tube is placed in a first position within a die, and the mold crimps the tube to form the desired indentation in the tube. The mold is then released, and the tube is moved relative to the mold to a second position. The mold again crimps the tube to form an additional indentation. Alternately, the mold includes a roller that forms a groove on the tube. The tube is translated or both translated and rotated relative to the mold to form the groove.

Un moule est placé dans des positions et une orientation voulues dans une matrice. Un tuyau est placé dans une première position dans la matrice, et ce moule gaufre le tuyau pour former l'indentation voulue sur ce tuyau. Le moule est ensuite libéré, et le tuyau déplacé par rapport au moule dans une seconde position. Le moule gaufre une nouvelle fois le tube pour former une indentation supplémentaire. Alternativement, le moule comprend un rouleau qui forme une rainure sur le tuyau. Ce tuyau et déplacé et pivoté par rapport au moule pour former la rainure.
