An apparatus and method for testing the integrity of a weld securing a flange to the end of a pipe comprises a testing assembly and a reinforcement assembly. The testing assembly comprises a first sealing means positioned within the pipe and a second sealing means secured against the flange face to form a sealed region within the pipe with the region overlapping the weld. The reinforcement assembly comprises a circumferential clamp secured to the outer wall of the pipe and an anchor plate positioned opposite the flange. The first sealing means is connected to the anchor plate to prevent relative movement there-between. The anchor plate is connected to the clamp to prevent relative movement there-between. The weld test procedure comprises installing the apparatus, filling and pressurizing the sealed space and monitoring the pressure created therein. The reinforcement assembly prevents the first sealing member from being separated and allows a weld test to be performed without a compressive force being applied on the weld. The invention also provides a reinforced tool and method for isolating an end segment of a pipe.
