Product Description

The nailing head pipe (needle pipe) strengthened heat exchange part is a series of cylinder welded on the surface of the steel pipe by the needle pipe automatic welding machine

2. Hexagonal circular welding in equal parts

Compared with the traditional manufacturing process of needle tube, foursquare type and hexagonal type needle tube strengthen the heat exchange element and adopt welding one-time forming, change the phenomenon of welding needle falling off after welding using tooling and forced stretching forming in the past, so that the welding of needle tube is firmer and the welding needle is not easy to fall off. Needle diameter, length, longitudinal spacing, number of circumferential needles and dip Angle are all factors that affect the heat transfer of needle tube. Therefore, it must be considered comprehensively and systematically in order to be more practical and applicable. Quadrature and hexagonal circular equipartition are used to arrange welding and needle tube, which has a larger spreading surface, and the needle tube has a disturbing effect on the fluid, which can greatly improve the heat transfer coefficient, especially suitable for high viscosity oil, heavy oil and other media to enhance heat transfer occasions.

Product features

As a new type of enhanced heat transfer element, the main advantage of the needle tube is to reduce the heat resistance and greatly increase the heat transfer coefficient.

2. As the needle assist is a cantilever structure, under the impact of airflow, the needle assist produces vibration, making it difficult for soot to accumulate; In addition, the needle tube heat exchanger element has a strong self-cleaning ability due to the strong plain current scouring of flue gas.

3. The needle tube has compact structure, low metal consumption per unit heat exchange, small volume and small floor space. The square and hexagonal needle tube heat exchange element has the advantages of good heat transfer performance, less ash accumulation, small volume and so on.
