Product Description

Product Description

Longitudinal Finned Tube Description

Crafted with meticulous precision, our finned tubes boast a high-grade construction from carbon, alloy, and stainless steel. Utilizing the sophisticated method of resistance welding with overlap (specifically Method 221 / RSEW), we ensure a product that stands at the pinnacle of durability and efficiency.

Our precision-engineered process employs a gentle regime of direct welding with side current, pairing fins on diametrically opposite sides of the tube. These fins, expertly crafted in a U-profile, significantly enhance the efficiency of heat transfer and fortify the structural integrity of the joint. This design innovation ensures even fin distribution around the tube's circumference. The fins are meticulously shaped through a gradual rolling process, minimizing internal stress in the final structure. A standout feature of our method is achieving a maximum profile length of 7 meters. While carbon steel is the typical material chosen for its superior heat transfer properties, we accommodate custom requests using high-strength steel, Cr-Mo-Ni alloys, and various grades of austenitic, ferritic, and duplex steels. Fin dimensions can be customized, with heights ranging from 5 to 32 mm, tailored to the customer's specific requirements. We use seamless tubes of matching materials, ranging from carbon to duplex steels (ASTM, EN, GOST standards), ensuring our longitudinally finned tubes maintain a precision tolerance of ± 6 mm.

Whether you require a single unit or a large-scale production, we are equipped to fulfill orders of any size. Our versatile offerings include straight or U-bent tubes, and we provide comprehensive equipment solutions to meet any heating or cooling need.

Our longitudinally finned tubes are indispensable in diverse sectors such as petrochemical, chemical, power generation, nuclear power, and the food industry. They serve as key components in heaters, coolers, heat exchangers, and other critical equipment.

The superior quality of our longitudinally finned tubes is underscored by their application in primary circuit equipment within nuclear power plants, where excellence is non-negotiable.
