Abstract

1496911 Vacuum-sealing ends of pipes NERATOOM BV 17 July 1975 [22 July 1974] 30106/75 Heading F2P A method of vacuum-sealing each of the first ends of a number of hollow transport means terminating in a header, characterized in that the header and/or the transport means are partially filled with a sealing material which is introduced into the header in liquid condition and subsequently converted into the solid condition. The figure shows pipes 1 having first ends in first header 4 and second end 3 in second header 5. The pipes run through the sodium compartment of a steam generator. When a leak is to be detected, the water supply is cut-off, the pipes and the sodium compartment are emptied and the pipes are refilled with an inert gas which differs from the detection gas to prevent a reaction at the leak spot between sodium residues and oxygen. Header 5 is separated from the steam line and the ends 3 are sealed for example with rubber. The first ends 2 are then vacuum-sealed. Each end 3 is then connected one by one to detector sensitive to detection gas and a pump, while detection gas, e.g. helium, is introduced into the empty sodium compartment. In the particular embodiment the sealing material is paraffin which becomes solid at ambient temperature. Paraffin is introduced into header 4 by means of a rubber balloon filled with heated and hence liquefied paraffin. The balloon is slid on to connection 6 and pressure on the balloon forces the paraffin into the header. Paraffin is prevented from flowing into the water supply by means of a valve or by means of a balloon 8 that can be introduced through connection 7 before being inflated. After the detection the header can be heated and the majority of the paraffin will liquefy and flow back into the balloon. Wax or Wood's alloy may be used instead of paraffin. The sealing material may be liquid at ambient temperature, in which case it is frozen or cured as applicable in situ.
