ABSTRACT:
A temporary pipeline capping unit wherein the unit is permanently attached over an opening in a pipeline and includes a capped branch line nipple and an internal element isolating the branch line nipple from the pipeline opening whereby a branch line can be connected to the pipeline by uncapping the branch line nipple and attaching the branch line to this nipple. The internal element is forced by the fluid pressure in the pipeline to a position communicating the subsequently installed branch line with the pipeline opening.
