Abstract

1,207,790. Plugging tube ends. WAAGNEBBIRO A.G. 1 July, 1969 [1 July, 1968], No. 33285/69. Heading F2P. Apparatus for inserting a plug into a tube end from a remote position comprises a plug having a closed end 13 and a deformable tubular wall portion 4, an expander 1 which extends into said wall portion, holdings means coacting with the plug, means such as a rotating screwthread in wheel 3 for pulling the expander out of the plug whilst the plug is held by the holding means 2, thereby to expand the plug wall portion into contact with the tube 12 wall, operating means (hand wheel 14, Fig. 1, not shown) remote from the plug &c. and transmission means, shaft 10b for transmitting movement from the operating means to the pulling means to actuate the latter. Preferably, the plug end 13 is welded to the tubular body portion 4 and means, e.g. a wet helium spectrometer may be used to test the weld. The apparatus is preferably provided with means for guiding and aligning the plug with the tube end and this is done in the embodiment of Fig. 1 (not shown) by a guide pin (16) for locating in an adjacent tube to the one to be plugged and a locating pin (11) for locating in a hole in a template (9) in a corresponding position to the tube to be plugged. The plug may be subsequently welded in position and for this purpose the expander, holding means and pulling means may be replaceable by a welding means.
