ABSTRACT:
A pipe connection comprising a tube of plastically deformable material has an expanded end section received in a hole in a tube plate with a sealing ring received in an annular seat in the hole sealing the tube to the plate. The extreme end of the tube may be deformed conically into contact with one side of the plate to provide a rigid structural joint therebetween. More than one sealing ring may be employed. Methods of making the pipe connection may involve constricting a portion of the end section to provide a space between the end portion and the tube plate hole to permit the seal to be inserted, followed by expansion of the tube end to compress the seal and engage the tube plate wall in metal-to-metal contact. Other variations of the process are disclosed.
