Product Description

Product Description

Longitudinal Finned Tube Description

Experience the epitome of precision with our expertly crafted finned tubes, meticulously engineered from top-tier carbon, alloy, and stainless steel. Utilizing the sophisticated resistance welding method with overlap (method 221 / RSEW), these tubes promise unmatched quality and performance.

Embrace innovation with our soft regime technique, which employs direct welding with side current. Each pair of U-profile fins is expertly welded on opposite sides of the tube, offering a groundbreaking alternative to conventional designs. This results in superior heat transfer efficiency, fortified joint strength, and a perfectly balanced fin distribution around the tube. Our fins are intricately shaped through gradual rolling, minimizing inner stress and maximizing structural integrity. This advanced method allows us to extend the profile length up to an impressive 7 meters. Typically crafted from carbon steel for optimal heat conduction, our fins can also be custom-made from high-strength steel, Cr-Mo-Ni steels, or specialty steels like austenitic, ferritic, and duplex, based on your requirements. Fins can be tailored in height from 5 to 32 mm, with angles customizable to meet your specifications. The seamless tubes mirror the material versatility of the fins, ranging from carbon to duplex steels (ASTM, EN, GOST standards). Our production process ensures precision manufacturing with tolerances of ± 6 mm for longitudinally finned tubes.

Catering to your every need, we produce quantities ranging from a single unit to large series. Our tubes are versatile, offered as either straight or U-bent, and we can supply complete equipment solutions for your convenience.

Our longitudinally finned tubes are indispensable across diverse industries such as petrochemical, chemical, power generation, nuclear power, and food industry sectors, serving crucial roles in heaters, coolers, heat exchangers, and a variety of other equipment.

Our unrivaled quality is affirmed by the implementation of our longitudinally finned tubes in the primary circuit equipment of nuclear power plants, setting a benchmark for excellence.
