Abstract: A split-sleeve type pipe device for assembly on a pipe for sealing off at a leak, hot tapping a pipe at a desired location, and electrically insulating the pipe for cathodic protection. The coupling includes a one piece gasket insulator having split annular end seal portions connected by longitudinal side runner seal portions, and a pair of housing halves which fit together over the gasket to form a sealed housing along the pipe. Annular portions extend axially from either side of each annular seal portion for insulating the pipe from the housing. One of the housing halves has an externally threaded side boss defining an opening into the housing through one of the shell halves for manipulation of pipe cutting equipment and for connection of a valve or other suitable equipment. Both housing halves have internal and external flanges for engaging annular electrical insulator portions. End set screws and compression rings are provided for gasket compression.

Abstract: Disclosed is an apparatus and method for connecting a fitting to a side wall of a pipe. The apparatus includes a frame comprising two ring clamps for mounting the frame on the pipe. Guide rods extend perpendicularly and outwardly of the pipe. A base plate is slidably mounted on the guide rods for movement relative to the pipe. A receiving member on the base plate is adapted to receive the fitting to be joined to the pipe. A top bar is fixedly attached between the ends of the guide rods remote from the rings. A threaded shaft is positioned with one end attached to the receiving member and with its second end passing through the top bar. Within the top bar are means for selectively engaging the threaded shaft so that the shaft may be translated through the top bar by turning the shaft. Alternatively, the shaft may be disengaged from the top bar whereby the shaft may be moved freely through the top bar.

Abstract: Disclosed is an apparatus for selectively connecting different sizes of service conduits to mains. The apparatus has a fitting with first and second bores therethrough. These bores are axially spaced and positioned in the fitting to radially extend from the main when the fitting is fixed thereto. A port adjacent the end of the fitting shaped for connection to the exterior of the main interconnects the two through bores. An annular flange is provided around a counterbore in the first bore for selectively connecting various sizes of service lines to the fitting. Internal threads are formed in the second bore for receiving an externally-threaded tapping means for manipulation axially through the bore to cut a coupon from the wall of the main to interconnect the main with the first bore. A sealing plug is provided for sealing the open end of the second bore.

Abstract: Disclosed is an apparatus for connecting a service line at a right angle to a main, having a fitting with one end shaped to be fixed to the exterior surface of the main in a plane with the fitting extending horizontally from the main. First and second through bores are formed in the fitting. These bores are axially spaced and positioned in the fitting to radially extend from the main when the fitting is fixed thereto. A port adjacent the end of the fitting shaped for connection to the exterior of the main interconnects the two through bores. Means is provided in the first through bore for connecting a service line to the fitting to extend radially from the center of the main. Internal threads are formed in the second through bore for receiving an externally-threaded tapping means for manipulation axially through the bore to cut a coupon from the wall of the main to interconnect the main with the first through bore. A sealing plug is provided for sealing the open end of the second through bore.
