Aluminum Fin Tubes

Product Details:

Production Capacity

• 2 Machines (2 Lines) Capable Of Manufacturing About 4,00,000 Mtrs. Of Helically Wound Wrap On Type Aluminium Fin Tubes (G , L , Kl) Per Annum. (can Be Increased)
• 1 Machines (1 Lines) Capable Of Manufacturing About 2,00,000 Mtrs. Of Extruded Fin Tubes (can Be Increased As We Are Waiting For The Delivery Of The Second Line).

Product Details:

Manufactured Exactly As The ‘ L’ Fin Except That The Base Tube Is Knurled Before Application Of The Fin Foot. After Application The Fin Foot Is Knurled Into The Corresponding Knurling On The Base Tube Thereby Enhancing The Bond Between The Fin And Tube Resulting In Improved Heat Transfer Characteristics. Maximum Operating Temperature For This Fin Type Is 260°C.

Aluminum Fin KL Type Knurled Fin Tubes

KL fin tube, also called kurling finned tube. Fabrication process is as follows:

Before continuous winding on the surface of steel tube, the outer surface of base tube should be rolled out. After winding, the fin foot is knurled into corresponding knurling on the base tube therefore enhancing the bond between fin and tube. Comparing with L type fin and LL type fin, it has better heat transfer.

Maximum working temperature: 260°

Applications:

• Chemical and petrochemical industry
• Steel mills, gas compression facilities and incinerators
• Heat exchanger for power plants (electric, nuclear, thermal and geothermal power plants)
• Food processing plants and refrigeration technology

Product Details:

An Electric Current Is Applied By Contacts On The Oval Studs And Tube And The Resistance In This Circuit Produces The Heat Necessary For Welding. Maximum Resistance And Therefore Maximum Heating Occur At The Interface Between The Stud And The Tube. Pressure To Forge The Oval Stud And The Tube Together At The Point Of Maximum Heating Is Applied By Various Forms Of Tooling. These Resistance Welding Processes Produce A Strong Metallurgical Bond Between The Stud And The Tube While Minimizing The Heat Affected Zone (HAZ) In The Tube. The Use Of Pressure To Forge The Oval Stud And The Tube Together Helps To Minimize The Heat Input Necessary To Make The Weld. This Product Is Used In Boilers Under Very High Pressure & Temperature Mainly In Sea Ships. This Production Is Done On The Latest And Most Modern Machine Among Those Installed In India. It Has The State Of Art Technology, With The Japanese Welding Controller Giving The Precise Secondary Current And Cycle Time, At The Time Of Welding, Which Result In The Desired Welding Quality. All The Welding Parameters Are Plc Controlled.

Production Technique & Applications

An Electric Current Is Applied By Contacts On The Square Fins (by Using Special Contours) And Tube And The Resistance In This Circuit Produces The Heat Necessary For Welding. Maximum Resistance And Therefore Maximum Heating Occur At The Interface Between The Fin And The Tube. Pressure To Forge The Square Fins And The Tube Together At The Point Of Maximum Heating Is Applied By Various Forms Of Tooling. These Resistance Welding Processes Produce A Strong Metallurgical Bond Between The Fin And The Tube While Minimizing The Heat Affected Zone (HAZ) In The Tube. The Use Of Pressure To Forge The Square Fins And The Tube Together Helps To Minimize The Heat Input Necessary To Make The Weld. This Product Is Used In Boilers Under Very High Pressure & Temperature Mainly In Steel Plants In Dirty Environment. This Production Is Done On The Latest And Most Modern Machine Among Those Installed In India. It Has The State Of Art Technology, With The Japanese Welding Controller Giving The Precise Secondary Current And Cycle Time, At The Time Of Welding, Which Result In The Desired Welding Quality. All The Welding Parameters Are Plc Controlled.
