Patent ID: 8887768

Claim:
A pipeline pressure testing fitting having a flow path through at least a portion of the fitting along a longitudinal axis of the flow path, the fitting having a port through which a pressure testing device is inserted to pressure test the pipeline, the pipeline having an interior diameter, the fitting comprising: fitting walls extending along but offset from the longitudinal axis to define at least a portion of the flow path through the fitting, the fitting walls having an interior and exterior side; a port having interior walls port defining a circular opening that is accessible from outside the fitting, the circular opening being centered on a central axis extending toward the longitudinal axis; two oppositely inclined, flat fitting walls on opposing sides of the centerline, each oppositely inclined, flat fitting wall defining an opening through which the flow path and longitudinal axis pass, the oppositely inclined, flat fitting walls spaced apart a distance sufficient so that a ball about 0.5 inches smaller than the nominal diameter of the pipeline can pass through the port and the flow path in the fitting, the oppositely inclined, flat fitting walls opposite the port being closer together than at the circular opening and spaced apart about 0.2 to 0.5 times the nominal diameter of the pipeline, the oppositely inclined, flat fitting walls further defining a recess at least partially encircling the flow path and opening to the circular opening.
