Title (EN) A JOINT
(FR) JOINT
Abstract: front page image
(EN)A joint between two hollow pipes (1, 2) is formed by inserting the pipes (1, 2) into the sleeve (100). The sleeve (100) is made of a similar or compatible material to that of the pipes (1, 2) which are to be joined. The pipes (1, 2) are held in position while the sleeve (100) is rotated. Due to the rotational and tangentional sheer stresses produced between the surfaces of the sleeve (100) and the pipes (1, 2) the multilayers for these surfaces form a uniform mixture. This mixing action eliminates the weld line present in known systems.
(FR)Joint monté entre deux tuyaux creux (1, 2) et formé par introduction des tuyaux (1, 2) dans un manchon (100). Le manchon (100) est réalisé en une matière semblable à celle des tuyaux (1, 2) à raccorder l'un à l'autre, ou compatible avec celle-ci. On immobilise les tuyaux (1, 2) puis on fait tourner le manchon (100). Les efforts de cisaillement tangentiel et circulaire créés entre les surfaces du manchon (100) et des tuyaux (1, 2) assurent la formation d'un mélange homogène à partir des couches multiples de ces surfaces. Cet effet de mélange élimine la perle de soudure présente dans les systèmes connus.
