Abstract
A method for fixing a tube by expansion improve the seal between a tube and a support plate which are joined by expansion fixing. The method comprises forming fine annular projections on the surface of a bore which is formed in the support plates, and inserting a tube within the bore so that upon expanding the tube within the bore, the projections engage the tube to produce a seal.
