ASTM A312 TP304 SUS304 1.4301 Heat Exchanger Fin Tube

HF Resistance Welding Usually Employs Frequency Of 400 kHz. The fin wound around the tube And Continuous weld. The fin strip is wounded spirally onto the tube and welded continuously with a high frequency electrical process to the base tube along the spiral root. ASTM A335 P11 P22 P9 P91 Carbon Steel Finned Tube For ASTM A335 P11 P22 P9 P91 CARBON STEEL FINNED TUBE FOR HEATER EXCANGER USE. HFW Solid Finned Tubes short for High Frequency Welded Helical Spiral Solid Finned Tube. Helical Finned Tubes provide the designer with high thermal efficiency and compact design solutions for a whole range of heat exchangers where clean flue gases are used.

China High Frequency Welded Fin Tube Suppliers

The fin is continuously welded to the tube by a high frequency electrical resistance welding process which leaves the tube essentially unchanged metallurgically. The width of the weld is always greater than 90 percent of the thickness of the fin, assuring a strong bond between the fin and the tube for efficient heat transfer and long life. China Hot dipped galvanized high frequency welded tube High frequency welded tube/ pipe:Standard:ASTM, DIN, ISO, EN, JIS, GB, etc. Material A53, A283-D , A135-A , A53-A, A106-A, A179-C, A214-C, A192, A226, A315-B, A53-B, A106-B, A178-C, A210-A-1, etc. Size Wall thickness:1.2mm-20mm, or as required. Outside diameter:20m-600mm, or as required. Length:1m-12m, or as required. Surface Finned Tube----High Frequency Welded Solid Fin Tube Helical Solid Finned Tubesare produced by helically wrapping continuous fin strip tube. The fin strip is wounded spirally onto the tube and welded continuously with a High Frequency Electrical process to the tube along the spiral root.

Finned Tubes-Welded Finned Tubes-Jiangsu haohua industry

The steel fin, that may be solid or serrated, is helically wound and continuously welded to the tube by high frequency electric resistance welding. This produces an homogeneous, clean and continuous fin-totube bond with no additional weld material, for a very efficient heat flow and resistance to corrosion. High Frequency Welded Fin Tube Spiral Fin Tube - Anand 11 rows · Welded Fin Tube. High Frequency Welded Fin Tube (Continuously Welded Spiral Fin Tube) :-. As the name suggests, in this type of Fin Tube the finning is a Spirally Wound. The fins are manufactured by Spirally Winding the fin around the Base Tube and Pipe. During the winding the fin is Continuously Welded by High Frequency welding giving the Most High Frequency Welding Helical Finned Tube - China The fin strip is wounded spirally onto the tube and welded continuously with a High Frequency Electrical process to the tube along the spiral root. The fin strip is held under tension and confined laterally as it is formed around the tube, thereby ensuring that the strip is in forceful contact with the tube surface.

ParsDETAIL. HIDE. The base tubes can be seamless or welded and made of carbon steel, alloy steelm, stainless steels, aluminium and copper alloys. This type is usually used in power generation for heat exchangers and in high corrosive systems in chemical and petrochemical industry. Process Welded Tubes, Inc.The edges of the formed tube are high frequency electric-resistance welded, providing a smooth contour and maintaining tight tolerances All mills are equipped with SPC control of OD to ensure a more consistent, on-spec product, which enables customers to maximize fabrication productivity and uptime.

Seamless Steel Pipe Manufacturing Process

Jan 25, 2019 · The hot-rolled steel pipe produced by this process is intrinsically different from the ordinary high-frequency welded pipe. After heating by the heating furnace, the metallographic structure and mechanical properties of the weld bead and the parent body can be completely consistent. In addition, the multi-pass tension reduction is achieved. Steel Tube Pipe Classification - fold11.Automobile axle casing with seamless steel pipe (GB3088-82) are manufacturing automobile axle casing and drive shaft Bridge shell effective quality carbon structural steel and alloy structural steel hot-rolled seamless steel tubes. 12.Diesel engine with high pressure oil pipe(GB3093-86) is to create effective high-pressure diesel injection Transportable gas cylinders Refillable welded steel gas This standard is one of a series of two standards concerning refillable welded steel gas cylinders of water capacities from 0,5 l up to and including 150 l for compressed, liquefied and dissolved gases:Part 1:Carbon steel Part 2:Stainless steel Annexes A, B and C
