Product Description

Product Description

Longitudinal Finned Tube Description

Elevate your industrial operations with our exceptionally high precision execution of finned tubes. Crafted meticulously from top-tier carbon, alloy, and stainless steel, these tubes are engineered using the cutting-edge resistance welding method with overlap (method 221 / RSEW), ensuring unmatched durability and performance.

Our tubes utilize a soft regime for welding, featuring direct welding with side current, ensuring precision and structural integrity. Fins are uniquely welded in pairs on opposite sides of the tube, taking on a U-profile shape. This innovative design outperforms traditional contact surface shapes by enhancing heat transfer efficiency, fortifying joint strength, and ensuring uniform fin distribution around the tube's circumference. The fins are expertly shaped through gradual rolling, minimizing internal stress in the final profile. This advanced technique allows for a maximum profile length of 7 meters. Our versatile fins, typically made from carbon steel for optimal heat transfer, can also be crafted from high-strength steel, Cr-Mo-Ni steels, austenitic, ferritic, and duplex steels, customized to your specific needs. Fin heights range from 5 to 32 mm, with angles tailored to customer specifications. Seamless tubes match the fin material range, from carbon to duplex steels (ASTM, EN, GOST). Our meticulous production method guarantees longitudinally finned tubes within ± 6 mm tolerances, tailored to perfection.

We are committed to flexibility and versatility, manufacturing any quantity from a single piece to large series. Our tubes are available as straight or U-bent configurations, and we offer comprehensive delivery solutions, including complete equipment integration.

Our longitudinally finned tubes are indispensable in the petrochemical, chemical, power generation, nuclear power, and food industries, serving crucial roles in heaters, coolers, heat exchangers, and various other equipment.

The superior quality and reliability of our longitudinally finned tubes are demonstrated through their application in primary circuit equipment within nuclear power plants, testifying to their exceptional performance under the most demanding conditions.
