Methods for producing an expansion compensator by: providing an inner plastic liner having first and second spaced apart ends, an inner surface, an outer surface, and an interior volume extending from the first end to the second end; positioning the inner plastic liner interior of an elongate metal conduit, the elongate metal conduit having first and second spaced apart ends, an inner surface, an outer surface, and an expansion/contraction section; heating the inner plastic liner; applying pressure to a fluid positioned in the interior volume of the inner plastic liner to expand the inner plastic liner whereby the expanded inner plastic liner has an expansion/contraction section; and cooling the inner plastic liner. |
