Longitudinal Finned Tube Description
High precision execution of finned tubes made from carbon, alloy and stainless steel using resistance welding method with overlap (method 221 / RSEW).
Soft regime is being used (direct welding with side current). Fins are welded always in pairs on the opposite sides of the tube. Fins are in the shape of U-profile. This solution in comparison to classic shape of contact surface offers better efficiency of heat transfer, improves the strength of the joint and helps to achieve an even distribution of the fins on the circumference of the tube. Fins are shaped by gradual rolling which results in minimum inner stress in the final profile. Another advantage this method brings is the maximum achievable length of the profile of 7 meters. The fins are usually manufactured from carbon steel (which offers good heat transfer), but they can be manufactured according to the request of the customer and according to the use from high-strength steel, Cr-Mo-Ni steels, austenitic, ferritic and duplex steels. Height of the fin can range from 5 to 32 mm, the angel depends on the specification of the customer. Seamless tubes are used in the same material range as the fins, that means from carbon up to duplex steels (ASTM, EN, GOST). The method and way of production ensure that we can manufacture longitudinally finned tubes in tolerances ± 6 mm.
We manufacture any quantity starting from 1 pc up to big series.The tubes are delivered as straight or U-bent tubes and we deliver also complete equipment.
Used in petrochemical,chemical, power generation, nuclear power industry and food industry in heaters, coolers, heat exchangers and other equipments.
The quality of our longitudinally finned tubes is also proven by their use on primary circuit equipment in nuclear power plants.
