The liner has an axis and is made of material having a different coefficient of linear expansion than the casing, and comprises at least one tubular section having an outer surface which defines at least one conical support section for resting against the support means at contact points with the support means. The contact points are located on generatrices of a conceived cone or pyramid, with the generatrices radiating from a fixed point on the axis of the liner coinciding with the tip of the cone or pyramid.
