Abstract

1,172,962. Stoppers for tubes. TEXACO DEVELOPMENT CORP. 16 Jan., 1968 [17 Jan., 1967], No. 2428/68. Heading F2P. A method of plugging a leaky tube 11, e.g. in a heat exchanger wherein the tube is attached at least at one end to a tube sheet 23 comprises inserting a cylindrical explosive type plug 38, having a charge therein, coaxially within the tube 11, locating the plug so that the charge is within the tube sheet 23 and detonating the charge to block the end of the tube within the tube sheet, the plug being formed of a thickwalled ductile material, e.g. brass, to avoid rupture when the charge is detonated. The plug 11 may be centred within an end of the tube, e.g. by wrapping tape around the plug at each end; preferably however, it is centred by spring steel spiders 39, 40 which are secured to the ends of the plug and which each have six legs. The plug has a centre electrode 49 for the electrical circuit of a detonator, not shown, housed within the plug, the electrode 49 being surrounded by a conductive sleeve 60 and an insulating insert 61 accommodated within an internally threaded head 50 of a tool for inserting the plug from the far end of a tube. The head 50 threadedly engages a hub extension 48 of the plug and is connected to a hollow flexible shaft 51 which is preferably made of a tightly laid helix. Insulated wires 57, 60 are connected respectively to the sleeve 60 and the head 50.
