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, Steel Plants, etc.

Stud fin tube is made by electrical Resistance welding specially formed Studs(Round pins ) in rows around the tube. The Studs can be supplied in a variety of Sizes and shapes. Also named pin fin tube.Stud tube have a very high heat transfer efficiency.The heat exchange efficiency is equivalent to 2-3 times that of the bare pipe. To increase the surface heat transfer coefficient of flue gas to the furnace tube.Reduce the amount of bare pipes used in these processes. (Heat transfer surface of one studded pipe is equivalent to surface of 4 to 10 bare pipes).
Studded tubes are generally used in furnaces and boilers where the surface is exposed to a very corrosive environment and where very dirty gas streams require frequent or aggressive cleaning.
Increase efficiency in the process of heat recovery and direct flame hostile atmospheres.
Studded Pipe’s ideal for processes applications where dirty fuels are used and harsh environments in terms of temperature and / or corrosion.Easier cleaning especially for operating cases with very dirty flue gas produced by burning heavy oil, diesel or residual oil.
Its high resistance to harsh environments, such as sections of Sulfuric Acid atmospheres, makes it very useful for the industries mentioned.

High frequency welded finned tube is a type of finned tube, which is mainly welded by high frequency welding and is a new type of excellent heat dissipation element. The high frequency welding finned tube is welded with high frequency current, the welding method is reliable and excellent, the welding seam is small, and the surface of the radiator is more solid as well as beautiful.
High frequency welded finned tube is a heat sink element often used in finned tube radiators. Welding high-frequency welded finned tube on the base tube of the radiator improves the heat transfer coefficient of the heat exchanger side of the radiator and enhances the heat dissipation effect of the radiator, and the excellent heat dissipation effect makes the finned tube more and more popular.
The high frequency welding finned tube is welded with high frequency current, which can increase the compactness of the radiator and improve the safety of the high frequency welding finned tube radiator in the operation process. The high-frequency welding process is an improved and upgraded process on the basic welding process, which is also a more excellent welding process.

Read MoreQuick ViewLongitudinal 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.

Read MoreQuick ViewStainless Steel U Bend Tube
U-shaped or U-bent tubes give the end user more freedom to design a more compact system than straight tubes do. The stainless steel U bend tube is perfect for applications involving heat and elevated pressure levels since it is frequently used in heat exchanger applications. An expansion joint would be used to join a straight tube in settings with exceptionally high temperatures. It would be terrible for the application if straight tubes’ thermal expansion was not taken into account.
Not to add, the price of the application is increased by the cost of using an expansion joint. However, when connecting a tube and a shell, a Stainless Steel U Bend Tube For Heat Exchanger allows for thermal expansion of the component without adding on or increasing the cost. As a result, employing stainless steel U-shaped tubes is not only effective but also economical. Although the component’s design is critical for its intended use, choosing the right grade when producing the stainless steel U-shaped tube is also a crucial factor. Stainless steel comes in a variety of grades on the market today.
Any grade of stainless steel tube U bend has an almost endless range of applications, from the highly affordable grade alloy 304 to the marine grade alloy 316. The Ss 316ti U Bend Tubes, which contain titanium added to its chemical composition, is one of the most attractive alloys since the durability of the application also comes into view. In particular, the alloy creates titanium carbide rather than carbide precipitates, which is not lethal to welded components, which improves the high temperature performance of the stainless steel welded U tube.
