| High Light | Corrosion Resistant Welded Longitudinal Finned Tubes ，High Temperature Tolerance Stainless Steel Heat Exchanger Tubes ，Enhanced Heat Transfer Oil Heat Exchanger Tubes | ||
Welded longitudinal finned tubes are advanced heat transfer components consisting of a stainless steel base tube with fins welded axially along its external surface, significantly increasing the effective heat exchange area compared to a smooth tube. This design enhances thermal performance and is especially suited for demanding environments such as oil heat exchange systems, petrochemical processing, and industrial utilities. Stainless steel materials are selected for this product due to their corrosion resistance, high temperature tolerance, mechanical robustness, and longevity in aggressive media.
Tube Type: Welded longitudinal finned tubes
Material Grades: Stainless Steel (e.g., SS304/304L, SS316/316L, SS321, Duplex grades)
Outer Diameter (OD): Typically 16 mm – 273 mm or customized depending on application requirements
Wall Thickness: 0.5 mm – 5 mm (typical range, application dependent)
Fin Height: Customizable per thermal design
Fin Attachment: Resistance (high‑frequency) welded longitudinal fins
Surface Finish: Annealed, pickled, or passivated for corrosion protection
Enhanced Heat Transfer: Fins dramatically increase surface area, boosting heat exchange efficiency over plain tubes.
Superior Corrosion Resistance: Stainless steel resists oxidation and corrosion even in harsh oil and chemical environments.
High Mechanical Strength: Suitable for high pressure and temperature service.
Wide Material Compatibility: Compatible with different heat exchanger designs and fluids, including oils, steam, and gases.
Long Service Life & Lower Maintenance: Robust design reduces fouling and extends operational life.
Optimized Heat Transfer Efficiency: Designed with fins engineered for maximum surface area, ensuring rapid and efficient heat exchange even with viscous oil media, improving thermal throughput compared to bare tubes.
Industrial‑Grade Material Supply: We source high‑quality stainless steel compliant with international standards (ASTM, EN, JIS) to ensure corrosion resistance and mechanical integrity in oil processing applications.
Precision Welding Technology: Our advanced resistance welding process yields consistent fin attachment with minimal defects, ensuring strong metallurgical bonds and long‑term reliability.
Customized Solutions & Technical Support: We work with customers on fin dimensions, tube sizing, and material grade selection based on specific oil heat exchanger requirements, reducing energy costs and optimizing system design.
Proven Performance in Harsh Environments: Stainless steel finned tubes are widely validated in petrochemical, power generation, and oil & gas heat exchanger systems for long‑term performance and reduced downtimes.
