About us

 

DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO.,LTD.) was established in 2002, which is located in Jiangsu, China. After many years of development, the company now has 66 million yuan in fixed assets, more than 200 employees, and 33 technical staffs. We have 4 aluminum processing production lines, with the annual processing capacity of more than 20,000 tons; And we have 5 tube-drawing production lines; 47 fintube production lines, 1 imported production line from American with the brand of McElroy , with the annual production capacity of 12 million meters the above. Quality is the theme of eternal pursuit of winner -Production workshop- Meticulous works, standardized management system and systematic quality assurance are Dellok(YONGHUI)'s best commitment to quality. In Dellok(YONGHUI), the quality control is not only the detection of the final process, but throughout the entire production process. We implement a set of quality control and assurance systems. Each batch of pipes is sampled and tested, and records are kept as a quality guarantee for the final product.

Properties:

This fin type is formed from a bi-metallic tube consisting of an aluminium outer tube and an inner tube of almost any material. The fin is formed by rolling material from the outside of the exterior tube to give an integral fin with excellent heat transfer properties and longevity. Extruded fin offers excellent corrosion protection of the base tube. Maximum operating temperature for this fin type is 280°C.

Fin material : Aluminium ,Copper

Tube materials : No theoretical limits.

 

Extruded Fin Tube

 

Product Description:

A carefully degreased core tube is fitted into an aluminium primary tube.This assembly is then fed into the triple-spindle finning head of the fin-extruding machine. Three special multi-disc packs extrude the aluminium tube into helical high fins while reducing the inner diameter to give firm pressure contact with the core tube
Fin materials: Aluminium
Base tube materials: Any metallic material

 

Extruded Finned Tube

 

Advantages:

100% fin-to-tube bond providing exceptional efficiency and longevity.
Excellent corrosion protection on the base tube.
Easy to clean with a high-pressure water jet without deforming the fins.
As the outer sleeve is continuous No galvanic corrosion between the tube and fins.
The bonding of the outer and inner tubes removes the risk of loss of contact with the aluminium due to thermal stress and fins are vibration resistant.
Higher heat transfer performance for the life of the unit.
Extruded Finned tubes are commonly used in applications with temperature up to 325 °c.
Extruded Aluminum Tubing

 

 

Feature Properities:

The extruded fin is formed from an outer aluminum tube with a large wall thickness (muff), which is aligned over an inner base tube. The two tubes are pushed through three arbors with rotating discs that literally squeeze or extrude the aluminum fins up and out of the muff material in a spiral shape in one operation. The resultant fin typically has a base or root thickness of .035"", average fin thickness .016"" and a tip of .009"", with an overall height of 16mm (5/8""). The root thickness serves to form an uninterrupted bond over the entire tube length.
Murphy disc technology now makes it possible to fin thinner muff thus offering significant material savings. Recommended standard muff wall is .176"" as opposed to industry practice of .183""-.210"" In addition, the same growth factor can be used for pitches from 8 - 11 FPI, allowing for standardization on one muff thickness and eliminating the need to stock multiple muff wall thicknesses. The same discs can be used to produce 5/8"" (15,9mm) or 1/2"" (12,7 mm) high fin.
Model B produces a 5/8"" high fin on tube sizes from 25mm to 1.5"" ( 38.1mm). The Model B Extruded Finning Machine is now capable of 7/16"" high integral copper fin at 7 to 10 FPI within the tube size range of the machine (25mm and 1.5""). Each machine is configured for the specific production requirements of the end user.

Extruded Aluminum Tubing

 

Aluminum extruded finned tubes using the form of the base tube covered with aluminum tube(the base tube can be carbon steel, stainless steel, copper) through machine extrusion, forming a tube fin, the fin base and the tube outer wall is close fitting, this fin tubing control can make finned tubes with high heat transfer coefficient and heat transfer performance.

Aluminum extruded finned tubes, also called [integral finned tubes" using the form of the base tube covered with aluminum tube(the base tube can be carbon steel, stainless steel, copper) through machine extrusion, forming a tube fin, the fin base and the tube outer wall is close fitting, this fin tubing control can make finned tubes with high heat transfer coefficient and heat transfer performance. Extruded Finned Tube can be made of iron, copper or aluminum tube by compound rolling, which has the advantages of tight bonding, small thermal resistance, good heat transfer performance, high strength, small flow loss, strong anti-corrosion performance, not easy to deformation under long-term hot and cold working conditions, long working life and so on.

Extruded finned tube manufacturing process

Pipe line--compressing or rolling--strip peeling--washing--pressure test--blast blowing--packaging.

The Extruded Fin Tube is formed by a bimetallic tube consisting of an aluminum outer tube and an inner tube of almost any material. The fin is formed by rolling the material from the outside of the outer tube to provide an integrated fin with excellent heat transfer performance and life. The extruded fins provide excellent corrosion protection for the base tube.

The production method of the composite finned tube mainly includes the extrusion method: the bimetallic composite tube is lined with a mandrel, and driven by the rotation of the roller blade, the composite tube is processed on the outer surface through the cavity formed by the rolling groove and the core head Out fins. The heat transfer tube produced by this method is an organic whole with its outer tube and fins, so there is no problem of contact heat loss, and it has good performance and high heat transfer efficiency.
