Pre-Machined Window Weld for Breached Tubing

Abstract

An example apparatus for replacement of a breached pipe section includes a first cylindrical pipe fitting having a first surface defining a first aperture, a middle pipe member, and a second cylindrical pipe fitting having a second surface defining a second aperture, and first and second aperture caps. A first end of each of the first and second pipe fittings is welded to opposite ends of the middle section, and a second end opposite of each of the first and second pipe fittings is welded through the respective first and second apertures to opposite ends of pipe surrounding the breached pipe section. The first and second aperture caps are welded to the apertures of the first and second pipe fittings to close the respective first and second apertures.
