ABSTRACT:
In one exemplar embodiment, a combination closure conduit and closure plug are provided for closing a side opening into a pipeline. The closure stub or conduit is attached to the pipeline around the side opening and has an interior annular shoulder. A closure plug adapted for insertion into the conduit has a projecting peripheral shoulder and provides a first sealing means. A peripheral sealing means disposed on the plug ahead of the peripheral shoulder provides a second means of sealing the plug to the conduit. Locking screws engage a peripheral surface on the top of the plug to lock the plug in place. A by-pass valve is carried by the plug to allow fluid communication through the plug during insertion of the plug.
