Title: Tubes of nuclear heat exchanger leak tested - and plugged if defective by units revolving stepwise on tube plates
Inventor: HODZIC ALIJA DIPL ING
IPC: F28F11/06
Filed: 1975-01-28
Abstract: An appts. and a method of localising and plugging leaking tubes in a straight tube heat exchanger of very large dimensions, esp. nuclear reactor heat exchanger, in which the tubes are arranged in concentric rings and are open at both ends to a header is arranged on the following basis. On the top and bottom tube plates of the heat exchanger there are two identical test units which can be lowered onto the plate (or raised in the case of the lower tube plate) and which are connected to a control desk. Each test unit comprises a frame in which there is housed a testing template and, between this template and the tube plate, a sliding perforated plate. The template and sliding perforated plate each contain a number of passages or holes at spacings equal to twice those of the heat exchanger tubes. The rows of passages and holes are aligned radially towards the heat exchanger centre. To operate the appts. each template is applied by a hydraulic or pneumatic ram onto the top of the tube plate, with the passages aligned with tubes of the heat exchanger. Each passage is connected to a control unit mounted in the frame, by which a test gas (typically air or helium) can be applied to the passage and thus to the associated heat exchanger tube. If a leak is found in a tube, then exploding rivets can be introduced into the tube ends and fired to plug them by means of ignition wires mounted in the perforated plate. Friction wheels driving on the inner face are used for rotating the entire units and fixing them in the desired position. Pref. the passages in the template are connected by Teflon (RTM) tubes, each offset from the associated passage to the central test unit.
