Product Description
Dellok G Embedded Fin Tube with Serrated Fins
Manufacturing Excellence
DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO.,LTD.), established in 2002 in Jiangsu, China, operates with 66 million yuan in fixed assets and employs over 200 staff including 33 technical experts. Our production capabilities include 4 aluminum processing lines, 5 tube-drawing lines, and 47 fin tube production lines, including an imported McElroy production line from America, delivering annual capacity of 20,000+ tons aluminum processing and 12+ million meters fin tube production.
Product Overview
The G Type Embedded Fin Tube features a fin strip wound into a precision-machined groove and securely locked by back filling with base tube material. This advanced manufacturing technique ensures maximum heat transfer efficiency with operational temperatures up to 450°C, maintaining optimal thermal performance at high tube metal temperatures.

Manufacturing Process
A helical groove is precision-formed in the base tube, displacing material. The fin is then wound into the groove under tension, followed by backfilling of the displaced material to permanently lock the fin root into the tube structure.
