Alloy Steel Fin Tubes Nail Head Tube Heat Exchange Element Needle Tube
Nail head tube (needle tube) enhanced heat exchange element is a series of cylindrical
welded on the surface of steel pipe by needle tube automatic welding machine, which is characterized by:
1. Tetragonal circumferential equal distribution welding;
2. Hexagonal circumferential equal distribution welding;
Compared with the traditional needle tube manufacturing process, the tetragonal and hexagonal needle tubes
strengthen the heat exchange elements by welding for one-time forming, which changes the phenomenon that
the welding needle falls off after using tooling forced tensile forming after welding, so that the needle tube is
welded more firmly and the welding needle is not easy to fall off. The welding needle, diameter, length,
longitudinal spacing, number of circumferential welding needles and inclination angle of welding needles are all f
actors affecting the heat transfer of needle tube. Therefore, it must be considered comprehensively and systematically
in order to have more practical application. The welding and needle pipes are arranged equally in the circumference of
tetragonal and hexagonal type, which has a larger expansion surface, and the needle pipe has a disturbance effect on the fluid,
which can greatly improve the heat transfer coefficient. It is especially suitable for the enhanced heat transfer occasions
of high viscosity oil products, heavy oil and other media.
Product features:
1. As a new type of enhanced heat transfer element, the main advantage of needle tube is to reduce the
thermal resistance and greatly improve the heat transfer coefficient.
2. Because the needle rib of needle tube is a cantilever structure, the needle rib vibrates under the impact of
air flow, making it difficult for soot to accumulate; Coupled with the strong turbulent scouring of flue gas,
the needle tube heat exchange element has strong self ash removal ability.
3. The needle tube has compact structure, low metal consumption per unit heat exchange, small volume
and small floor area. Square and hexagonal needle tube heat exchange elements have the advantages of
good heat transfer performance, less ash accumulation and small volume. They have broad application
prospects in heat exchange and energy saving projects.
