Tube heat exchanger advantages Details: This tube heat exchanger has a number of distinct advantages, it is still widely used in petrochemical and other industrial sectors. ① simple structure, increase or decrease the heat transfer area freely. Because it is made of a combination of standard components, the installation without additional processing. ② high efficiency heat. It is a pure countercurrent heat exchanger finned tube radiator heat dissipation, but also can select the appropriate cross-sectional dimensions, in order to improve the fluid velocity, increase the heat transfer coefficient of the fluid on both sides, so it's a good heat transfer. Liquid - liquid heat exchanger, the heat transfer coefficient of 870 ~ 1750W / (m 2 · ℃). This is particularly suitable for high pressure, low flow, low heat transfer coefficient of the heat transfer fluid. ③ simple structure, large work adjustment range, easy to increase or decrease the heat transfer area, both sides can increase the flow rate of fluid, so that both sides of the heat transfer surface can have a higher heat transfer coefficient; drawback is that metal consumption per heat transfer surface capacity, maintenance, cleaning and demolition are more trouble drying room finned tube radiators, separable connections likely to cause leaks. To increase the heat transfer area, improve heat transfer effect, the inner tube wall additional forms of fins, and the addition of membrane perturbation means scraping the inner tube, in order to meet the high viscosity of the fluid heat transfer. Finned tube radiator production and optional parameters 1: Quality requirements finned tube finned tube pitch 6-7 mm, fin height should be greater than 15 mm radiator fin tube radiator fin rake angle should not be greater than 80 straightness per meter finned tube should not be greater than 1.0 m m. For high frequency welding process finned tubes, finned tubes per meter to measure the sum of the actual weld length should be greater than 85 finned tube radiators, and No continuous weld length should not exceed 50 mm 2:. steel finned tube convectors welding quality requirements: steel and steel pipe GB 151 to comply with the provisions of the collusion. Welding shall conform to GB / T 985's. 3: steel finned tube convectors should cover before adding pressure test by group or pneumatic test, the test pressure is 1.5 times the working pressure. 4: steel finned tube convectors take over the thread shall comply with JG .1 31's. 5: film quality steel finned tube convectors should spray anti-rust primer and topcoat; panel should paint, paint preparation should comply with GB / T 1727's. Surface coating should be uniform and smooth, firmly attached, without bubbles, accumulation, flow and leakage jet.
