Product Description
Manufacturer Profile
DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO.,LTD.), established in 2002 and located in Jiangsu, China, specializes in high-quality heat exchanger manufacturing. With 66 million yuan in fixed assets and over 200 employees including 33 technical staff, the company operates 4 aluminum processing lines, 5 tube-drawing lines, and 47 fin tube production lines, including an imported McElroy production line from America.
Extruded Bimetallic Fin Tube Technology
This advanced fin type is formed from a bi-metallic tube consisting of an aluminum outer tube and an inner tube of various materials. The fin is created by rolling material from the exterior tube to produce an integral fin with superior heat transfer properties and extended service life.
Manufacturing Process
A polished and deoiled base tube is set in an aluminum sleeve. The assembly passes through a fin machine with three spindles set at 120° angles, each bearing a stack of plates that build the fin and bond the outer and inner tubes together.
Performance Advantages
100% fin-to-tube bond for exceptional efficiency and longevity
Excellent corrosion protection on the base tube
Easy cleaning with high-pressure water jet without fin deformation
No galvanic corrosion between tube and fins
Vibration resistant with thermal stress protection
Higher heat transfer performance throughout unit lifespan
Suitable for applications up to 325°C
Technical Properties
Maximum Working Temperature: 300°C
Atmospheric Corrosion Resistance: Excellent
Fin Materials: Copper, Aluminum (Alu.1100, Alu.1060, Alu.6063)
Base Tube Materials: Carbon steel (A179, A192, A210), Stainless steel (A269/A213 T5 T11 T22 304 316), Copper alloys, Titanium
Industrial Applications
Extruded Fin Tubes are widely used in refinery, petrochemical and chemical industries for:
Air-cooled condensers
Air-cooled coolers for products
Gas coolers
Gas heaters

Technical Overview
Aluminum extruded finned tubes use a base tube covered with an aluminum sleeve (carbon steel, stainless steel, or copper base) processed through machine extrusion to form integral tube fins. This manufacturing process ensures the fin base and tube outer wall maintain close contact, resulting in finned tubes with high heat transfer coefficients and superior thermal performance.
