Product Description

Product Description

Longitudinal Finned Tube Description

Discover the pinnacle of precision with our high-grade finned tubes. Crafted from carbon, alloy, and stainless steel, these tubes are expertly constructed using the advanced resistance welding method with overlap (method 221 / RSEW), ensuring seamless performance and durability.

Our innovative soft regime technique (direct welding with side current) ensures that fins are symmetrically paired on the tube's opposite sides, forming a unique U-profile. This state-of-the-art design surpasses traditional contact surfaces, offering superior heat transfer efficiency, enhanced joint strength, and uniform fin distribution around the tube. Crafted through meticulous gradual rolling, the fins boast minimal internal stress, extending up to an impressive maximum length of 7 meters. While carbon steel is our standard material choice, we offer a spectrum of options including high-strength steel, Cr-Mo-Ni steels, and various grades of stainless steel such as austenitic, ferritic, and duplex, tailored to specific customer requirements. Fin heights range from 5 to 32 mm, with customizable angles to meet unique specifications. Our seamless tubes match the material range of the fins, spanning from carbon to duplex steels (ASTM, EN, GOST). This precise production process allows us to deliver longitudinally finned tubes with tolerances as tight as ± 6 mm.

We cater to all order sizes, from a single piece to large-scale series. Our tubes are available as straight or U-bent, and we can supply complete equipment packages to meet all your needs.

Our longitudinal finned tubes are indispensable in a myriad of high-stakes industries such as petrochemical, chemical, power generation, nuclear power, and food processing. They excel in applications including heaters, coolers, heat exchangers, and a variety of other critical equipment.

The exceptional quality of our longitudinally finned tubes is underscored by their reliable performance in the primary circuit equipment of nuclear power plants.
