Patent ID: 7827853

Claim:
A weld testing assembly for testing one or more welds securing a nozzle to a vessel, said nozzle having a stem portion welded to an opening in the vessel wall and an opposite flange portion extending outward from said opening, the assembly, when in an installed condition, comprising: a generally annular first anchoring member adapted to be sealingly mountable against said flange portion of the nozzle, the first anchoring member including a generally central opening; a generally annular second anchoring member adapted to be sealingly mountable against the inner surface of said vessel wall and overlapping the opening in the vessel wall, the second anchoring member including a generally central opening; an annular body extending between said first and second anchoring members, said annular body being adapted to extend into the stem portion when in the installed condition, and wherein said annular body includes a lumen extending there-through; a first sealing means for forming a seal between said annular body and said first anchoring member or said stem portion; and, a second sealing means for forming a seal between said annular body and said second anchoring member; whereby, when said assembly is in the installed condition, a sealed annular space is formed between the first and second sealing means, the annular body, and the stem portion, said space being capable of being pressurized for conducting a weld test; and wherein, in the installed condition, the generally central openings of the first and second anchoring members and the lumen of the annular body align to form an open channel through the nozzle for allowing communication between the interior and exterior of the vessel during the test.
