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.

    A355 Seamless Alloy Steel Tube

    The A335 pipes has a high level of Chromium and Molybdenum presence in it. While Molybdenum increases the overall strength, resistance, elasticity, hardenability and overall quality, moly ensures that the material is more resistant to softening, restrains the growth of grains and lessens the chances of embrittlement. It is the single additive that is responsible for the increase in high temperature resistance and it also improves the corrosion resistance to steel.

    Copper Fin Tube

    Copper is a metal element, and pure copper is a soft metal. The surface is reddish orange with metallic luster when it is just cut open, and its simple substance is purple-red. Good ductility, high thermal conductivity and electrical conductivity, so it is the most commonly used material in cables and electrical and electronic components.

    It can also be used as a building material and can be composed of many alloys. Copper alloys have excellent mechanical properties and low electrical resistivity. The most important ones are bronze and brass. Sebagai tambahan, copper is also a durable metal that can be recycled multiple times without compromising its mechanical properties.

    Copper pipes (also known as red copper pipes) are commonly used in tap water pipes, heating and cooling pipes, and can be used in different environments. Copper pipes combine the advantages of metal and non-metal pipes in cold and hot water systems. Copper pipes are resistant to high temperatures and can be used in a variety of environments. Compared with this, the shortcomings of many other pipe materials are obvious.

    Tabung Sirip Aluminium

    Bahan sirip aluminium benar-benar menutupi tabung, kecuali di ujung di mana lapisan tabung dapat diterapkan. Di mana korosi atmosfer hadir dan ketika dioperasikan dalam batas suhu desain, tabung bersirip yang diekstrusi memberikan kinerja paling stabil dari waktu ke waktu dibandingkan dengan jenis sirip lainnya. Sirip digulung dari tabung aluminium luar dengan proses menggunakan tekanan untuk membuat "ikatan tekanan" yang digulung antara tabung liner dan sirip.

    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.

    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.

    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, Pabrik Baja, dll.
