finned tube radiator can exchange the same amount of heat, which can greatly reduce the size of the equipment and reduce metal consumption. The developed finned tube , its cost performance and heat transfer efficiency, etc., must not have cracks, pores, or defects. Defects such as weld penetration and burn-through; several times to dozens of times that of a plain tube, it can enhance heat transfer and reduce flow resistance. Welding finned tubes use high-frequency current and are welded while winding, so the base tube and fins are basically Becoming one, the welding rate is an important indicator for judging the quality of finned tubes. The thickness of the welded finned tube is usually above 1.0. Due to the limitation of the processing technology, the height of the fin should be smaller than the radius of the base tube. If it is required to make high fins, it can be made into toothed fins.
When fin tube radiators naturally dissipate heat, the flow of air is driven by temperature differences. The surface temperature of high-efficiency fin tubes is very high, but the temperature difference is not enough to drive the flow of air, so the heat stays on the surface of the fins. Partly, this is because the air also has viscosity. When the power is insufficient, most of the hot air sticks to the vicinity of the fins and does not flow, resulting in a decrease in the heat exchange effect. steel fin tube radiator has high pressure bearing capacity, which has been improved from the industry standard mpa to the enterprise standard, an increase of 20%.
Steel fin tube convection radiator is a steel fin tube radiator suitable for both steam systems and hot water systems. It is used as a heating air. It is mainly used for hot air heating and air conditioning systems. The air heating of and drying device is the main equipment in the hot air device. Steel finned tube convection radiators are widely used in the heating and ventilation systems of industrial and mining enterprises and large buildings at this stage; the appearance of steel finned tube convection radiators is inspected. Each welding part should be flat and smooth, and the processed surface at the interface should be fine and ensure verticality and flatness. The surface coating should be even and smooth, firmly adhered, and should have no bubbles.
