Abstract
A method of supporting a metal tube during an overcasting process includes radially supporting the metal tube from within an interior opening of the metal tube with a compressed granular material. The compressed granular material is held in place by a first stop and a second stop positioned at opposite axial ends of the metal tube. A tensile connector, such as a rod or a cable, interconnects and attaches the first stop and the second stop. Compressive radial forces exerted onto the metal tube during the overcasting process are transferred through the granular material and resisted by a tensile force in the tensile connector.
