Our mill facilities enable our producers to deliver a variety of fin, stud, tube and size combinations according to our clients' needs. The products we supply has the most minimized production problems and the testing time of the equipment.
We supply the best quality welded finned tubes from high frequency resistance welding (FRW) machines. The steel fin can be solid or serrated and is helically wound and continuously welded to the tube by HFW systems. The size and dimensions of the fins can be adjusted according to client requirements.
Finned Tubes Outside Diameter: 1" to 8"
Fin Thickness: 0.9 to 3mm
The studs are welded to the tubes using electrical resistance welding, producing high quality welds. Studded tubes are mostly employed in preference to finned tubes in heat transfer systems in petrochemical plants, where the surface is exposed to very corrosive environment such as dirty gases or liquids. These tubes should be resistant to aggressive materials and must be cleaned frequently.
Studded Tubes Outside Diameter: 60 to 220mm
