ABSTRACT:
A plastic tube and tube end cap for installation in a metal tube or the like when the metal tube is positioned extending through a passage in a tube sheet, such that the plastic tube and end cap cooperate to accurately position an explosive charge which, when detonated, causes the plastic tube to expand outwardly against the metallic tube with such force that the metal tube makes intimate contact with the respective passage through which it extends in the tube sheet, without contaminating or damaging the metal tube in the process. The subject plastic tube and tube end cap have portions which cooperate to hold them together and further cooperate so that when the plastic tube is inserted into the metal tube the explosive charge will be accurately positioned. The end cap may optionally have openings therethrough which are located to relieve the expansion forces at a selected location produced during an explosion, and the end cap has a portion which can be deformed to permit positioning an explosive cord therein but which prevents movement of the cord when the deforming forces are relieved.
