Since 1984, DuraFin Tube has grown from a fabrication and weld shop into a Minerva, Ohio manufacturer of custom finned and enhanced-surface tubing for heat-transfer systems. Its in-house tooling, machine shop, and project-management approach let the company develop specialized formed tubing and heat-exchanger solutions from prototype through production, including one-off retrofits. DuraFin Tube operates an ISO 9001-certified quality system and can provide ASME-certified heat exchangers and subassemblies to customer designs.
