초록

A method of establishing a leak tight and structural connection between a core tube and an accommodating header plate in a tubular heat exchanger, including the steps of positioning the core tube into bores of the header plate and a braze foil, installing a ferrule inside the core tube end, radially expanding the ferrule in the core tube end, thus expanding the core tube end into intimate contact with the header plate in which it is received, deforming a ferrule into pinching contact with the braze foil plate, directing the flow of the braze material tow...
