Yuhong Group has been operating stainless steel/duplex/nickel seamless pipes and finned tube for more than 30 years, with annual sales of more than 80,000 tons of stainless steel/duplex/nickel seamless pipes. Our clients have covered more than 45 countries. Our stainless steel seamless pipes are widely used in mining, energy, petrochemical, chemical, food mills, paper mills, gas and fluid industries and more. ANSI B16.10: B16.19 SCH 5S, SCH 10S, SCH 20, SCH 30, SCH 40S, SCH 60, SCH80S, XS, SCH 100, SCH 120, SCH160, XXS.
Extruded finned tubes are bimetallic tubes whose outer aluminium surface is finned by cold plastic deformation.
Helical solid finned tubes are made by helically wrapping a continuous strip of fins around the tube. High frequency resistance welding typically uses a frequency of 400 kHz. The fins are wrapped around the tube and welded continuously. The fin tape is helically wound on the tube and continuously welded to the base tube along the root of the helix by a high frequency electrical process. The fin strips are held under tension and laterally constrained as they are formed around the tube, ensuring firm contact between the fin strips and the surface of the base tube. Using the gas metal arc welding process, the continuous welding is made at the point where the fin strip first begins to bend around the diameter of the pipe.
