Product description: Kaineng needle tube reinforced heat exchange original is a needle tube automatic welding machine to weld a series of cylindrical shapes to the surface of the steel pipe. Its characteristics are: 1. Square circumference equal distribution welding; 2. Hexagonal circumference equal distribution welding. Compared with the traditional needle tube manufacturing process, square and hexagonal needle tubes strengthen the heat exchange element and are molded once by welding. In the past, the welding needle falls off after forced stretching with special tooling after welding, so that the needle tube is welded more firmly, and the welding needle is not easy to fall off. The pin diameter, length, longitudinal spacing, circumferential number of pins, and the inclination of the needle are all factors that affect the heat transfer of the needle tube. Therefore, it must be considered comprehensively and systematically in order to be more practical. In addition, the needle tube has a disturbance effect on the fluid, and can greatly improve the heat transfer coefficient, and is especially suitable for the strengthening heat transfer occasions of high-viscosity oil products, such as crude oil, heavy oil and other media. Product features: 1. The needle tube is a new type of reinforced heat transfer element. Its main advantage is to reduce thermal resistance and greatly improve the heat exchange coefficient. 2. Since the needle rib of the needle tube is a cantilever structure, the needle rib vibrates under the impact of the airflow, which makes it difficult for soot to accumulate. Coupled with the strong turbulence of the flue gas, the needle tube heat exchange element has a strong self-cleaning ability. 3. The needle tube has compact structure, low metal consumption per unit heat exchange, small size, and small footprint. 4. Square and hexagonal needle tube heat exchange elements have the advantages of good heat transfer performance, little ash accumulation, small size, etc., and have broad application prospects in heat exchange and energy saving projects. Product advantages: 1. Compared with the traditional needle tube manufacturing process, square and hexagonal needle tubes strengthen the heat exchange elements, and use welding to form once, changing the situation of forced stretching with special tooling after welding in the past, so that the needle tube is welded more firmly, and the welding needle is not easy to fall off. 2. Square, hexagonal needle tube structure, so that the flue gas is washed horizontally or vertically, all needle expansion surfaces are washed by flue gas horizontal turbulence, the airflow forms a symmetrical steady state vortex and reflow zone on the cylindrical back of the needle rib, and the thermal boundary layer is continuously destroyed and reformed, so that the entire heat exchange surface boundary layer is thinned, and the thermal resistance is greatly reduced Increase the heat exchange coefficient. 3. Since the needle rib of the needle tube is a cantilever structure, the needle rib vibrates under the impact of the airflow, which makes it difficult for soot to accumulate. Coupled with the strong turbulence of the flue gas, the needle tube heat exchange element has a strong self-cleaning ability. 4. The needle tube has a compact structure and low metal consumption per unit of heat exchange. It is an enhanced heat transfer element worth popularizing.
