Manufacturing Process
Double walled steel tubing is manufactured from electrolytic copper-coated steel strips wound into continuous tubular form with double-layered walls. The assembly is then copper brazed in a special furnace using the coated copper as filler metal, ensuring strong, reliable bonds throughout the structure.
