Product Description

Product Description

Longitudinal Finned Tube Description

Experience unparalleled precision with our high-precision execution of finned tubes crafted from premium carbon, alloy, and stainless steel. Utilizing the state-of-the-art resistance welding method with overlap (method 221 / RSEW), each tube exemplifies superior craftsmanship and reliability.

Our advanced soft regime welding technique (direct welding with side current) ensures fins are always paired and welded on opposite sides for optimal efficiency. The innovative U-profile shape offers superior heat transfer, enhanced joint strength, and an even fin distribution around the tube's circumference. Through gradual rolling, we achieve a profile with minimal inner stress, boasting a remarkable maximum length of 7 meters. We typically use carbon steel for its excellent heat transfer properties, yet we accommodate customer-specific requests with high-strength steel, Cr-Mo-Ni steels, and austenitic, ferritic, and duplex steels. The fin height ranges impressively from 5 to 32 mm, tailored to meet customer specifications. Our seamless tubes are crafted from the same diverse materials, from carbon up to duplex steels (ASTM, EN, GOST). This meticulous method allows for manufacturing tolerances of ± 6 mm in our longitudinally finned tubes.

We pride ourselves on flexibility, manufacturing any quantity from a single piece to large series. Our tubes are available in both straight and U-bent configurations, and we also provide fully assembled equipment to meet all your needs.

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

The unmatched quality of our longitudinally finned tubes is further validated by their prominent use in primary circuit equipment within nuclear power plants, ensuring reliable performance and safety.
