Abstract
A method for connecting a pipe fitting with a buried pipe from above ground in which the top, outer wall surface of the buried pipe is exposed to an aboveground location, producing an exposed outer wall surface. An opening into the pipeline is formed at the exposed outer wall surface following which a fitting to be connected with the pipeline is inserted through the opening into the pipeline and connected with a circumferential pipe surface encircling the opening into the pipeline. Preferably, keyholing techniques are used to carry out the steps of the method so as to substantially limit the amount of excavation required compared with conventional pipe fitting connection procedures.
