Product DescriptionProduct DescriptionFinned tubesFinned tubes are a type of heat exchange tube that is installed with fins on the surface of ordinary straight tubes by welding, winding, rolling, etc. to increase the surface area (or inner surface area) of the heat exchange tube, thereby achieving the purpose of improving the heat exchange efficiency.Finned tubes are mainly used in the field of heat exchange, and their working principle is to enhance the heat transfer process by increasing the heat transfer area.During the heat exchange process, heat is transferred from the hot fluid to the fins through the tube wall, and then transferred from the fins to the cold fluid.Since the fins increase the surface area of the tube, the heat transfer area between the hot fluid and the cold fluid is greatly increased. At the same time, the fins can also destroy the boundary layer of the fluid and reduce thermal resistance, thereby improving the heat exchange efficiencyRolled finned tubeWrapped finned tubeThe fins are tightly combined with the base tube through the rolling process, and the heat transfer efficiency is high.Specifications Tube diameter: 25mm, 32mm, 38mm, 42mm, 57mm, 76mm, 89mm, 108mm, etc. Fin height: 10mm, 15mm, 20mm, 25mm, 30mm, etc. Fin thickness: 0.5mm - 2.0mm, common fin thicknesses are 0.8mm, 1.0mm, 1.2mm, 1.5mm, etc.Fin spacing: 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, etc. Tube length: 1m, 2m, 3m, 4m, 5m, 6m, etc., special lengths can also be customized according to actual needs.The metal strip is wrapped around the base tube, which is suitable for high temperature environmentsTube diameter: 25mm, 32mm, 38mm, 42mm, 57mm, 76mm, 89mm, 108mm, etc. Fin height: 10mm, 15mm, 20mm, 25mm, 30mm, etc. Fin thickness: 0.5mm - 2.0mm, common fin thicknesses are 0.8mm, 1.0mm, 1.2mm, 1.5mm, etc.Fin spacing: 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, etc. Tube length: 1m, 2m, 3m, 4m, 5m, 6m, etc., special lengths can also be customized according to actual needs.Welded finned tubeFinned tubeThe fins are fixed to the base tube by welding, and the connection is firm, which is suitable for high pressure environments.Tube diameter: 25mm, 32mm, 38mm, 42mm, 57mm, 76mm, 89mm, 108mm, etc. Fin height: 10mm, 15mm, 20mm, 25mm, 30mm, etc. Fin thickness: 0.5mm - 2.0mm, common fin thicknesses are 0.8mm, 1.0mm, 1.2mm, 1.5mm, etc.Fin spacing: 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, etc. Tube length: 1m, 2m, 3m, 4m, 5m, 6m, etc., special lengths can also be customized according to actual needs.The fins are put on the base tube, suitable for low temperature environment.Tube diameter: 25mm, 32mm, 38mm, 42mm, 57mm, 76mm, 89mm, 108mm, etc. Fin height: 10mm, 15mm, 20mm, 25mm, 30mm, etc. Fin thickness: 0.5mm - 2.0mm, common fin thicknesses are 0.8mm, 1.0mm, 1.2mm, 1.5mm, etc.Fin spacing: 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, etc. Tube length: 1m, 2m, 3m, 4m, 5m, 6m, etc., special lengths can also be customized according to actual needs.SpecificationItemDetailsTypeExtruded fin - tubeManufacturing processInsert a smooth core tube into an aluminum tube, and then extrude fins from the aluminum tube.Base tube materialStainless steel, carbon steel, alloy, titanium, nickel, copper, etc.Fine materialAluminum strip, copper stripProduct DimensionsBase tube diameter: 10mm - 51mm; Base tube wall thickness: 1.65mm - 3mm; Fin thickness: 0.3mm - 1.2mm; Fin pitch: 2mm - 15mm; Fin height: 5mm - 16mmAdvantagesThe bond between the outer and inner tubes eliminates the risk of contact loss caused by thermal stress; fins are more rigid; the core tube is well - protected against corrosion by the aluminum sleeve. The contact thermal resistance remains stable in a large temperature range, and the heat transfer performance is excellent. It is easy to clean with high - pressure water jet, and the fins are not easy to deform and fall off; there is no galvanic corrosion between the tube and fins, and it has good vibration resistance.Maximum working Temprature280 °C - 300 °CApplication ScenariosPetroleum, chemical, and petrochemical industries; natural gas treatment; steel industry (blast furnace and converter cooling systems); power generation (steam turbine exhaust condensing, fossil and nuclear power plants); air - conditioning; household waste incineration; compressor coolers, etc. It is also widely used in heat exchangers of power plants, chemical plants, food processing plants, and is the main equipment for air coolers.Company ProfileCompamny descriptionHebei Cangtie Industrial Co., Ltd. is one of the large enterprises specializing in steel pipes and pipe fittings in Hebei Province.
