Spiral finned tubes can be manufactured in a variety of ways. The finned tubes used in boilers, pressure vessels and other heat exchange equipment mainly include the following manufacturing methods: high frequency resistance welding spiral finned tubes, brazing spiral finned tubes and Integral helical finned tube. High frequency welded spiral finned tube High-frequency welding spiral [...]
Helical finned tubes are a highly efficient heat transfer element with helical fins. Its heat transfer area is several times to dozens of times that of the light pipe, which can enhance heat transfer, reduce flow resistance, and reduce metal consumption, thereby improving the economy and operational reliability of heat exchange equipment. ASTM SA179 Spiral [...]
Steel-aluminum finned tube is a kind of steel-aluminum composite tube which is rolled after compounding. It has the characteristics of tight bonding, low thermal resistance, good heat transfer effect and good corrosion resistance. By adding fins on the surface of the heat exchange tube, the outer surface area of the heat exchange tube is increased, [...]
The finned tube radiator is currently the most widely used steel-aluminum finned tube (wound finned steel-aluminum composite finned tube, rolled finned steel-aluminum composite finned tube), which utilizes the pressure resistance of steel pipe and the strength of aluminum. High-efficiency thermal conductivity, compounded on a special machine tool. Its contact thermal resistance is almost zero under [...]
The concept and operation of a shell and tube heat exchanger are rather simple and are based on the flow and thermal contact of two liquids. The name of a shell and tube heat exchanger serves as an explanation of the process, which is the exchanging of temperature between two fluids. In a heat exchanger, [...]
1) The heat exchanger should be tested for water pressure at 1.5 times the maximum working pressure. The steam part should not be lower than the steam supply pressure plus 0.3MPa; the hot water part should not be lower than 0.4MPa. Under the test pressure, keep the pressure without drop for 10min. shell tube heat [...]
What are the characteristics of steel and aluminum finned tubes for radiators? The steel-aluminum finned tube for the radiator adopts the steel tube around the aluminum fin process, which is smooth without burrs, no wrinkles, and easy to clean. It is easy to remove the condensed water on the surface of the fins during wet [...]

The trapezoidal section formed by rolling the L type finned tube is consistent with the distribution of the heat flow density, the tubes are tightly combined, and the thermal efficiency is high, which eliminates the contact thermal resistance caused by the inability to eliminate the gap between the tubes of the serial finned tube. Spiral [...]
Winding finned tubes are a widely used type of finned tubes. Its total heat conduction area is several times to dozens of times larger than that of the bare tube, which can improve heat conduction and reduce frictional resistance. The winding finned tube is small in size, light in weight and easy to install. Wire [...]
The production principle of the extruded finned tube is as follows: A mandrel is lined in the bare tube, driven by the rotation of the roller blade, the seamless steel tube is processed into fins on its outer surface through the cavity formed by the rolling groove and the core head. The finned tube produced by [...]
Greenhouse finned tubes are also called galvanized finned tubes.The finned tube for greenhouse is used in the greenhouse, which can provide a reasonable growth environment for the plants in the greenhouse. Greenhouse finned tube is a commonly used cooling equipment component in the heating system and drying system in the greenhouse field. The finned tube [...]
The first step in the production of steel and aluminum finned tubes is to purchase steel pipes. The steel pipes first have high compressive strength and high pressure. Low thermal conductivity and good thermal insulation performance. Fluid resistance is small. Aluminum tube series: thick-walled round tube diameter 15mm---160mm, wall thickness 2.0mm-40mm; thin-walled round tube diameter [...]
The main function of the finned tube radiator is to dissipate heat. So it functions better than some normal heatsinks, and it dissipates heat just as well. Upon closer inspection, we found that the main material of the device is basically aluminum, not copper. Why do finned tube radiators use aluminum fins instead of copper [...]
Advantages of HF Welded Helical Finned Tubes HF Welded Helical Finned Tubes is one of the most widely used spiral finned tubes, and is now widely used in power, metallurgy, waste heat recovery in the cement industry and petrochemical industries.
