Claim:
A method of securing a cylindrical screen jacket to a base pipe, the base pipe having a pertinent outer diameter, the cylindrical screen jacket having a plurality of elongated ribs extending axially along the inner diameter thereof and at least one wire wrapped radially around the elongated ribs in multiple spaced wraps, the method comprising: separate from the base pipe, forming the cylindrical screen jacket with an original inner diameter that is equal to or smaller than the pertinent outer diameter of the base pipe; inserting the cylindrical screen jacket into an oven or furnace; heating the cylindrical screen jacket in the oven or furnace to expand the cylindrical screen jacket so that the inner diameter of the cylindrical screen jacket becomes greater than the pertinent outer diameter of the base pipe; positioning the base pipe at least partially within the heated cylindrical screen jacket; and allowing the cylindrical screen jacket to cool and shrink fit onto the base pipe to form an interference fit between the elongated ribs and the base pipe.
