ABSTRACT:
A mechanical weldable fitting for use in tapping a pipe includes a first and second metal collar, each formed of attachable upper and lower semi-toroidal portions that when assembled on the pipe providing spaced-apart external cylindrical surfaces. Each collar having at least one internal circumferential sealing groove therein that receives a gasket formed about the pipe. A lower semi-tubular metal containment member is positioned on the external cylindrical surfaces of the collars. An upper semi-tubular metal containment member is positioned on the external cylindrical surfaces of the collars. The upper containment member having an integral upwardly extending tubular access portion affording passage for tapping the pipe. The upper and lower containment members are welded to each other and to the collars to fully encompass a portion of the pipe.
