A method of providing access to the interior of a cross-line (18) that intersects with a primary pipeline (14) of equal or greater diameter includes the steps of attaching a branch fitting (22) to the exterior of the primary pipeline, affixing a full opening valve to the branch fitting, securing a hot tap machine (46) to the valve (26), using the hot tap machine (46) to cut an opening in the primary pipeline (14) of a diameter at least equal to the internal diameter of the cross-line (18), and removing the machine leaving an access diametrically through the valve (24) and primary pipeline (14) into the interior of the cross-line (18) for installing pipeline inspection or cleaning pigs (30) and/or a locking plug (26). A rotation resistor (132) facilitates securing a locking plug (76) within the pipeline (18).

L'invention porte sur un procédé permettant d'accéder à l'intérieur d'une ligne transversale (18) qui croise un conduit primaire (14) de diamètre égal ou supérieur. Ce procédé consiste à relier un raccord secondaire (22) à l'extérieur du conduit primaire, à fixer une soupape de pleine ouverture au raccord secondaire, à fixer une pince de branchement (46) afin de découper une ouverture dans le conduit primaire (14) d'un diamètre au moins égal au diamètre interne de la ligne transversale (18), et à ôter la pince afin de laisser un accès dans le sens diamétral à travers la soupape (24) et le conduit primaire (14) jusqu'à l'intérieur de la ligne transversale (18) afin d'installer des racleurs de conduit (30) et/ou une fiche de verrouillage (26). Une résistance pivotante (132) facilite la fixation d'une fiche de verrouillage (76) dans le conduit (18).
