Brief: Discover the production process of G Type Finned Tubes, embedded fin tubes designed for high-efficiency heat exchangers. These stainless steel pipes feature a secure mechanical interlock, ensuring durability and thermal performance in demanding applications.
Related Product Features:
  • Secure mechanical interlock with embedded fins for high vibration and thermal cycling resistance.
  • High thermal efficiency with continuous metal-to-metal contact for optimal heat transfer.
  • Service temperature capability up to ~450°C, suitable for various industrial applications.
  • Corrosion-resistant base tubes available in multiple stainless steel grades (304L/316L/321/347/2205).
  • Customizable fin geometry (height, thickness, pitch) to meet specific project requirements.
  • Straightness and dimensional tolerance optimized for tight tube sheet fit without rework.
  • Pressure integrity ensured through hydrostatic or NDE testing per ASTM A1016/EN 10216-5.
  • Thermal design support for fin height/pitch optimization to balance performance and compactness.
