Product Description

Product Description

Longitudinal Finned Tube Description

Crafted with the utmost precision, our longitudinal finned tubes are engineered from premium carbon, alloy, and stainless steel. Utilizing a sophisticated resistance welding method with overlap (method 221 / RSEW), these tubes ensure reliability and durability.

Embracing a soft welding regime, our design features direct welding with side currents, where fins are expertly welded in pairs on opposing sides of the tube. These U-profile fins surpass conventional contact surfaces, delivering superior heat transfer efficiency, enhanced joint strength, and an evenly distributed fin arrangement around the tube. Gradual rolling shapes the fins, minimizing internal stress and extending the profile length up to an impressive 7 meters. Typically crafted from carbon steel for optimal heat conduction, we also tailor fins to meet specific customer requirements using high-strength, Cr-Mo-Ni, austenitic, ferritic, or duplex steels. Fin heights range from 5 to 32 mm, adjustable to customer specifications. Employing seamless tubes from carbon to duplex steels (ASTM, EN, GOST), our method ensures accurate manufacturing tolerances of ± 6 mm for all longitudinally finned tubes.

Whether you need a single piece or large-scale production, we can fulfill any order size. Our versatile tubes are available as straight or U-bent configurations, and we provide comprehensive equipment delivery to meet all project needs.

Our longitudinal finned tubes find their applications across a variety of industries, including petrochemical, chemical, power generation, nuclear power, and the food industry. They are integral components in heaters, coolers, heat exchangers, and other essential equipment.

The unparalleled quality of our longitudinally finned tubes is validated by their critical application in the primary circuit equipment of nuclear power plants, ensuring safety and performance.
