Coiled Copper Fin Tube
Copper fin coils are also special coils that Grand provide. These coils don’t have a bi-metallic bond usually found on standard coils and have a copper wavy fin pattern bonded to the copper tubes.
These coils are very reliable heat exchangers as they are required and can operate for air conditioners in harsh coastal areas and other highly corrosive surroundings because the coils have higher coastal corrosion durability. The coils match this type of environment because the bi-metallic construction is not present, and copper has a natural protective film and a mono-metal bond attaching the tube and fin. They have superb thermal conductivity, resistance and strength compared to aluminium.

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. Krome, 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.

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, Ŝtalfabrikoj, ktp.

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.

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,kupro,aluminium,titanio,ktp;) are used in heat exchangers (air, water and chemically cooled)for various industries such as petroleum, petrochemical, ŝtalo, power generation and many more.
