Description

ASME SA179 Cold Drawn Economizer Tube

The SA179 cold drawn economizer tube is a low carbon steel seamless tube manufactured to ASME SA-179/SA-179M, offering superior surface finish and dimensional precision through the cold drawing process. Designed for economizer banks in waste heat recovery boilers, it maximizes heat absorption from exhaust flue gases before they exit the stack.

Key Features

  • Cold Drawn Precision: Tighter OD and wall thickness tolerances compared to hot-finished tubes for consistent heat transfer performance
  • Bright Surface Finish: Cold drawn finish enhances corrosion resistance and facilitates fin welding in economizer coil fabrication
  • Low Carbon Steel (≤0.18% C): Excellent ductility and cold formability for bending into serpentine economizer coils
  • ASME SA179 Compliant: Meets all requirements for seamless cold-drawn low-carbon steel heat exchanger and condenser tubes
  • Cost-Efficient: Economical material choice for low to medium temperature (<400°C) heat recovery applications
