A method of centralizing a tubing in a wellbore includes providing one or more expandable elements between the tubing and a surrounding casing located in a wellbore and expanding the expandable elements against the casing so as to cause the tubing to become centered within the casing. Alternatively, one or more portions of a tubing are expanded against a surrounding casing located in a wellbore so as to cause the tubing to become centered within the casing.
