Abstract
Unión tubular, en la que los extremos de tubo presentan rebordeados 6 ensanchamiento simétrico al eje en la zona de los lugares de choque, con una abrazadera apretable radialmente hacia adentro y con perfil en forma de U, en la superficie interior, estando chaflanados respecto al eje del tubo las caras frontales interiores de la abrazadera y/o las caras frontales de los rebordeados 6 ensanchamientos opuestas al lugar de choque, de manera que los lugares de choque de los extremos de tubo se presionan uno contra otro al estar apretada la abrazadera, caracterizada porque al menos la parte anular más exterior radialmente de la abrazadera presenta una protuberancia a modo de orejeta deformable plásticamente, mediante cuya contracción se aprieta el anillo y se establece la unión tubular.
