| High Light | Operational Temperature up to 350–400°C Studded Tube ，Extruded Fin Studded Tube ，Thermal Shock Resistance Studded Tube | ||
The ASTM A106 Gr.B Cu-T2 embedded fin tube combines the structural strength of carbon steel tubes with the high thermal conductivity of copper, delivering excellent heat transfer performance, superior thermal shock resistance, and long-term operational reliability in high-temperature environments of 350–400°C. Its unique embedded fin structure eliminates the risk of fin detachment commonly associated with traditional high-frequency welded fin tubes, making it particularly suitable for industrial equipment subject to significant temperature fluctuations and demanding heat transfer requirements. This material combination offers an optimal balance of cost-effectiveness and high performance, making it a preferred solution in medium-to-high temperature heat exchange applications.
1.Excellent Thermal Conductivity
2.Outstanding Thermal Shock Resistance
