boiler tube,High pressure boiler tubes are used in high temperature and high pressure conditions. Steel tubes are subject to oxidation and corrosion under the action of high temperature flue gas and water vapor. The steel tube is required to have high lasting strength, high oxidation resistance corrosion performance and good stability.

    Aluminium Fin Tube

    The aluminum fin material completely encloses the tube, except at the ends where a tube coating can be applied. Where atmospheric corrosion is present and when operated within design temperature limits, extruded finned tubes provide the most stable performance over time as compared to the other fin types. The fin is rolled from an outer aluminum tube by a process using pressure to create a rolled “pressure bond” between the liner tube and fins.

    Extruded Fin Tube

    Extruded fin tube is rolled as an integrity with no thermal contact resistance, high intensity, featured in thermal shock and mechanical shock resistance. Heat exchangers assembled with this kind of fin tube (extruded fin type) is much better than the one equipped with string fin tubes or hectically wound fin tubes (L/LL/KL type fin).

    Extruded Finned Tubes, also known as “Integral Finned Tubes”. Integral finned tubes are manufactured by rolling process on tubes. During finning operation, the inside diameter of the tubes is reduced and helical fins are rolled on the tube wall. The tubes material can be Copper Alloy, Brass Alloys, Copper Nickel Alloy, Titanium Alloy, Stainless Steel, Duplex Stainless Steel etc. The pressure required to extrude fins from the aluminum sleeve creates an excellent “pressure bond” between the two materials.

    Copper and aluminum com-posited fin tubes are rolled from a muff copper tube, advantaged in tight link, small thermal resistance, good heat transfer efficiency, small flow loss and strong corrosion resistance. When working in long time under heating and cooling conditions, they are durable and not easy to deform.

    The integral extruded fin tubes is smooth on surface and easy to clean. When wet cooling in heating and air conditioning project, it is easy to remove the condensation water on the outer surface of the fin, and it is not easy to dust and scale in the heating and other heat exchange.

    Longitudinal Finned Tubes

    Longitudinal finned tubes are produced by welding the fins with resistance along the length of the tube. The fins first form a u-shaped channel, allowing each of the u-shaped legs to form a fin. The channel is cut to the appropriate length and then welded into place along the length of the tube and resistance. The channels are a pair of welded, polar opposites, so the number of fins specified must be a multiple of four.

    For a given tube or tube size, the desired heat transfer surface area per tube unit length can be obtained by specifying the appropriate fin height and number of fins. The maximum number of fins depends on the outer diameter of the tube – the larger OD tube can accommodate more fins.

    Stud Fin Tube

    The STUDDED Fin Tube is manufactured by Resistance Welding of Studs on the Bare tubes.

    The fins are manufactured by welding of the Fin Material which is essential a stud or rod welded at base to the tube by Electrical Resistance Process.

    The current is made to flow through the Tube and the base of the studs. The studs are specifically made in shapes to facilitate the welding process. The Stud; during the finning “welding” process is also mechanically pressed on the tube at the point of welding thence causing a very good mechanical bond. This type of Fin Tube find very good application in high pressure and high temperature applications. The mechanical bond is very strong and hence finds application in places where extreme mechanical load, stress is expected while during the process or cleaning etc.

    These Fin Tubes find application in Finned Pipes, Air Coolers, Heat Exchangers etc and are preferred in Industries like Petrochemical Refineries, Power Plants, Chemical Industries, Siderúrgicas, etc.

    Seamless Fin Tube

    A fin tube is a tube that has small fins around the outside surface.

    These fins act as a filter and a mechanism to transfer heat from the material inside the tube to the outside space or vice versa. Fin tubes are used in applications that require a transfer of heat from a hot fluid to a colder fluid through the tube’s wall.

    Grand provide a wide range of fin tubes(carbon, stainless,cobre,aluminium,titânio,etc;) are used in heat exchangers (ar, water and chemically cooled)for various industries such as petroleum, petrochemical, aço, power generation and many more.

    100Tubo de aço do rolamento Cr6

    Tubo de aço para rolamentos refere-se a laminados a quente ou a frio (trefilado a frio) tubo de aço sem costura usado para a fabricação de anéis de rolamento comuns. O diâmetro externo do tubo de aço é 25-180mm, e a espessura da parede é 3.5-20mm, que pode ser dividido em dois tipos: precisão ordinária e maior precisão. O aço do rolamento é usado para fazer esferas, Rolos e anéis de rolamento. O rolamento trabalha sob grande pressão e atrito, portanto, o aço do rolamento é necessário para ter dureza alta e uniforme, resistência ao desgaste e alto limite elástico.

    Os requisitos para a uniformidade da composição química, o teor e a distribuição das inclusões não metálicas, e a distribuição de carbonetos de aço de rolamento são muito rigorosas. É um dos tipos de aço mais rigorosos em toda a produção de aço.
