アルミフィンチューブ

Grand Aluminum L-Foot Tension Wound Finned Tubes are an economical solution for applications requiring greater resistance to vibration and heat cycling typical of air cooled heat exchangers. The L-Foot design mechanically locks the fins and provides broader contact surface between tube and fin.

Below you will see common L-Foot Tension Wound Finned Tube configurations:

Tube Sizes: 1/2″ O.D. to 2″ O.D.
Fin Heights: 1/4″ to 5/8″
フィンピッチ: 4 宛先 13 fins per inch
Temperature: Up to 300°F

Grand’s Edge Tension Wound Finned Tubes offer a low cost solution for low to moderate temperature applications. The surface of the tube is knurled as the fin is wound tightly on edge around the O.D. of a tube to ensure proper fin to tube contact.

Edge Tension Wound Finned Tubes are commonly used in applications with small amounts of vibration and metal temperatures up to 250° Fahrenheit.

Tube Sizes: 1/2″ O.D. to 2″ O.D.
Fin Heights: 1/4″ to 1″
フィンピッチ: 4 宛先 13 fins per inch

Grand's Embedded Fin Tubes offer solutions where higher temperatures, continuous thermal cycling and tube vibration due to high velocity air streams can cause failures. The fin is mechanically embedded into a groove that is plowed in the tube O.D. and is locked into place by rolls that force the groove to tightly close around the fin base.

Tube Sizes: 9/16″ O.D. to 2″ O.D.
Fin Heights: 1/4″ to 5/8″
フィンピッチ: 5 宛先 13 fins per inch

Grand's Extruded Finned Tubes provide the greatest resistance to atmospheric corrosion. アルミフィン素材がチューブを完全に囲みます, チューブコーティングを適用できる端部を除く. 大気腐食が存在する場所、および設計温度制限内で操作した場合, 押し出しフィン付きチューブは、他のフィンタイプと比較して、時間の経過とともに最も安定した性能を提供します. フィンは、圧力を使用してライナーチューブとフィンの間に圧延された「圧力結合」を作成するプロセスによって、外側のアルミニウムチューブから圧延されます.

Extruded Finned Tubes are commonly used in applications with temperatures up to 550 華氏.

Tube Sizes: 1″ O.D. 宛先 1 1/4″ O.D.
Fin Heights: 1/2″ to 5/8″
フィンピッチ: 8 宛先 11 fins per inch

Grand’s Perforated Finned Tubes maximize heat transfer by increasing the air flow across the finned area of the tube. Uniform perforations are created in the fin as it passes through the machine. These perforations are arranged like spokes of a wheel and can manufactured in Embedded and L-Foot fin configurations. Perforated Fins can manufactured out of aluminum or copper.

Tube Sizes: 9/16″ O.D. to 2″ O.D.
Fin Heights: 1/4″ to 1″
フィンピッチ: 4 宛先 13 fins per inch

Belled end tubes are required in applications where finned tubes for maintenance purposes must pass through stationary tube sheets. Tex-Fin’s integral belled end finned tube eliminates the need for expensive silver brazing of the tube to bell and greatly extends the life of the belled end finned tube beyond that of any mechanically attached belled end.
