Product description: 1. The efficient energy-saving needle tube double sleeve developed by our company adopts independently developed and patented hexagonal reinforced heat exchange needle tube technology. The hexagonal reinforced needle tube includes heat exchange tube, hexagonal arrangement, and cylindrical needle welded on the surface of the heat exchange tube in equal parts. 2. The hexagonal equal circumferential arrangement has a larger expansion surface, and the needle tube has a disturbing effect on the fluid, which can greatly improve the heat transfer coefficient. It is especially suitable for the strengthening heat transfer of high-viscosity oil products, such as crude oil, heavy oil and other media. 3. Cylindrical needles are welded to the outer wall of the heat exchange pipe at one time through the needle tube automatic welding machine independently developed by our company and patented. Compared with the traditional needle tube manufacturing process, welding is used for one-time molding, which changes the forced stretching of special tooling after welding in the past, so that the needle tube is welded more firmly, and the welding pin is not easy to fall off. Product features: In order to improve the heat transfer effect of the needle tube, the optimal combination of the length, diameter, spacing and inclination of the needle tube, etc., and the optimal design of the needle tube structure, can strengthen the heat transfer, less scale during operation, and corrosion resistance, especially the high-viscosity fluid structure and coking problem, and the ash accumulation problem of high-temperature corrosive smoke and dust gas, which is unmatched by other reinforced heat transfer pipes Superiority. Product advantages: 1. Most of the existing boiler heat exchange pipes are single-tube type. The pipe wall may be damaged by stress during processing, or affected by corrosion during use, causing the pipe wall to break. Light weight reduces the heat exchange effect, and heavy damage the unit. The heat exchange effect of the needle tube is not as good as the heat exchange effect of the needle tube. 2. In order to overcome the above problems, our company develops and produces high-efficiency and energy-saving needle tube double sleeve, which has a compact structure and a unit change%E thousand fishing shop https://27044.qianyuwang.com/
