S/T Trufin in Copper-Nickel Alloys Tube Type S/T Trufin is designed for boiling and condensing of hydrocarbons and other liquids. Integral helical fins on the outside of the tubes provide an increase in outside surface area, in effect, minimizing a low heat transfer coefficient normally encountered when evaporating a liquid or condensing a vapor. The inside diameter is basically a smooth surface.

L-Foot Tension Wound Finned Tubes Aluminum L-Foot Tension Wound Finned Tubes are an economical solution for applications requiring greater resistance to vibration and heat cycling typical of air cooled heat exchangers. The L-Foot design mechanically locks the fins and provides broader contact surface between tube and fin.   Below you will see common L-Foot Tension Wound Finned Tube configurations: Tube Sizes: 1/2″ O.D. to 2″ O.D. Fin Heights: 1/4″ to 5/8″ Fin Pitch: 4 to 13 fins per inch Temperature: Up to 300°F   Edge Tension Wound Finned Tubes Edge Tension Wound Finned Tubes offer a low cost solution for low to moderate temperature applications. The surface of the tube is knurled as the fin is wound tightly on edge around the O.D. of a tube to ensure proper fin to tube contact.   Edge Tension Wound Finned Tubes are commonly used in applications with small amounts of vibration and metal temperatures up to 250° Fahrenheit. Tube Sizes: 1/2″ O.D. to 2″ O.D. Fin Heights: 1/4″ to 1″ Fin Pi

Studded Tubes: The steel studs are automatically resistance welded to the tube, producing high quality forge welds. Our automatic studding machines are capable of handling tube diameters from 60mm o/d to 219mm o/d and standard stud diameter of 12.7mm. The welding process enables the combination of any grades for studs and tube: carbon, alloy, stainless steels and high nickel alloys. Alloy steel pipes are stress-relieved after studding, according to the relevant specifications for the class and grade of steel used. Studded Tubes Corrosion protection: If required, the external surfaces of studded tubes can be treated with a protective coating. Our engineers are always ready to assist you with design considerations to meet your specific product needs. Uses of Studded Tubes Steel studded tubes are used instead of finned tubes for heat transfer in the petrochemical industry, generally in furnaces and boilers where the surface is exposed to a very corrosive environment and where very dirty g

High Frequency Finned Tubes: 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. There are some applications for which one or the other fin type is preferred. While in some cases fouling and cleaning considerations will favour solid fins, serrated fins are superior with respect to weight, compactness and price. The use of high-frequency current results in very localised heating of the tube surface and the edge of the fin. This skin effect produces higher weld speeds, hence post-weld heat treatment is not considered necessary because of the superficial nature of the changes in the microstructure. High Frequency Finned Tubes bending: Our finning machines are equipped with online single or duplex cold bending equipment that can manipula

Corrugated Stainless Steel Tubing is stainless steel tubes with helical groove obtained from a plain tube by cold forming. The quantity of Helix and Angle could be designed to optimize the heat transfer performance. Corrugated Tube designed for shell and tube heat exchangers Characteristicas: 1. High efficiency of heat transfer coefficient in corrugated tube heat exchanger. 2. Similiar with normal tubes without dead zone. 3. Lower exchange area in corrugated tube heat exchanger. 4. Lower fouling in corrugated tube heat exchanger.Because of the self-cleaning effect provided by the higher fluid turbulence. 5. Shorter residence times of heat exchanger, because we need’t stop to clean the corrugated heat exchanger. 6. Longer running times with corrugated tube in corrugated tube heat exchanger.  7. Increasing fluid turbulence when flowing through, its means that turbulent flow can take place even with low Reynolds number. In fact, while for a plain surface tube the transition regime between

The extruded finned tubes are produced by compressing an aluminum tube. Aluminum fin is formed from bi-metallic tubes, a base tube and an aluminum muff tube. The fins are formed on a cold rolling process from the wall thickness of the aluminum muff tube. Extruded fin gives very good corrosion protection to the base tube, as the base tube is not visible to the atm

HFW Serrated Finned Tubes is short for High Frequency Welded Helical Spiral Serrated Finned Tubes Helical serrated finned tubse, serrated fins cut from metal strip and then helically wound around the tubes. Others are same as high frequency welded solid finned Tubes Pipes. The important features of this configuration are Efficiency, effective bond of fins to tubes under all conditions of temperature and pressure, and ability to withstand high fin side temperatures. This serrated fin configuration is even better to withstand the fin fouling if that is a problem in the application. This gives better heat transfer properties compared to solid fins Base Tube Details Tubes Diameter  Range: 15.88 mm to 219 mm Tubes Thickness Range: 1.651 mm to 16mm Tube Material:  Carbon Steel Seamless Tubes, Stainless Steel, Carbon Alloy Steel, Corten steel, duplex stainless Steel, Super Duplex Stainless Steel S32750, Inconel Alloy, High Chrome High Nickle Incoloy alloy, CK 20 material and some other mater
