DELLOK YONGHUI G EMBEDDED FIN TUBE

Product Specification

^{DELLOK YONGHUI G EMBEDDED FIN TUBE}

^{I. Product Overview}

^{DELLOK YONGHUI G-type Embedded Finned Tube is a high-performance heat exchange element designed specifically for heat exchange industry applications. It employs advanced "G"-type embedded technology, perfectly integrating the fins with the base tube to achieve an optimal balance of heat transfer efficiency, mechanical strength, and corrosion resistance. This product is widely used in various boilers, air preheaters, waste heat recovery systems, drying equipment, and heating and ventilation systems, making it an ideal solution for improving energy efficiency and reducing operating costs.}

^{II. Core Features and Advantages}

^{1. Superior Heat Transfer Efficiency}

^{A. Embedded Design: The fins are tightly embedded in the base tube wall and rolled, eliminating contact thermal resistance between the fins and the base tube, ensuring near 100% metal-to-metal contact.}

^{B. Large Area Expansion: The fins significantly increase the outer surface area of ​​the tube, increasing the heat exchange capacity on the air or flue gas side several times over, significantly improving overall heat exchange efficiency.}

^{2. Unparalleled Structural Strength and Stability}

^{A. Permanent Metal Bond: Unlike wound or sleeved finned tubes, the G-type embedded process makes the fins an integral part of the base tube.}

^{B. Vibration and Impact Resistance: The fin roots are firmly anchored in the base tube, capable of withstanding strong airflow erosion, mechanical vibration, and physical impact, effectively preventing fin loosening or deformation and extending service life.}

^{C. High Pressure Resistance: The base tube itself remains intact, with pressure resistance comparable to bare tubes, suitable for high-pressure conditions.}

^{3. Excellent Corrosion and Wear Resistance}

^{A. Smooth Fin Roots: The smooth surface created by the embedded process reduces the possibility of dust and corrosion accumulation.}

^{B. Robust Fin Structure: Capable of withstanding harsh airflow environments containing dust and particulate matter, reducing the wear rate.}

^{C. Material Options: Base tubes and fins can be combined from various materials such as carbon steel, stainless steel, and alloy steel, depending on the characteristics of the medium, to cope with different corrosive environments.}

^{4. Long Service Life and Low Maintenance Costs}

^{Due to its superior wear and corrosion resistance, the service life of DELLOK YONGHUI G-type finned tubes far exceeds that of ordinary finned tubes.}

^{The stable structure reduces downtime for maintenance due to fin damage, saving customers significant maintenance costs and time.}

^{III. Technical Principles: G-Type Embedded Process}

^{The manufacturing process of G-type embedded finned tubes (G-Fin Tubes) involves precision rolling a spiral groove into the smooth outer wall of a base tube (usually a steel pipe) using specialized equipment. Simultaneously, the bottom of the strip-shaped fin material is embedded and pressed into the groove. Finally, through rolling, the base tube metal tightly wraps around the fin root, forming a robust mechanical interlocking structure. This process does not involve welding, avoiding weld corrosion and heat-affected zone problems.}
