Abstract
PURPOSE: A pipe is expanded by using a mandrel having O rings separated by a distance equal to a length to be expanded. The mandrel is freely inserted into the pipe, and pressured liquid is supplied through the mandrel inlet into the gap between the pipe and the mandrel. This means economically provides reliable, multipiped heat exchangers.
CONSTITUTION: The mandrel 5 is provided with O rings 7 into the ring grooves 6. The mandrels 5 are inserted into the pipes 2 installed on the holes 2 of the plate 1 through the pipe gaps 3. Pressure liquid is supplied through the inlet 8 of the mandrel 5 into the gap between the pipe 4 and the mandrel 5. Liquid is sealed by the O rings 7,7 and not leaked. Liquid presses the pipe internal 5 against the pipe hole 2 to expand it, Since liquid pressure is used for pipe expansion, pressure control is correct and easy, and assurs uniform pipe expansion.
