Wound L LL KL G Fin Tube Machine
Wound L LL KL G Fin Tube Machine can produce L-type finned tubes, LL-type finned tubes, KL / KLM-type finned tubes, and G-type embedded finned tubes. The finned tubes are usually made of aluminum (copper) fins.
- Production types: Carbon steel pipes, stainless steel pipes, copper pipes
- Finned tubes: G-type/L-type/LL-type/KL-type/KLM-type; copper-aluminum finned heat dissipation tubes.
- Embedded type: Using disc-shaped blades, the tube is grooved to a depth of 0.35~0.4mm and a width of 0.5~0.55mm; aluminum (copper) fins are wound into the grooves and pressed tightly by a pressure roller next to the blade, ensuring the aluminum (copper) fins are firmly embedded in the copper or steel pipe.
Datang has been manufacturing finned tubes and fin tube machines for nearly 20 years. Our experienced technicians can provide video guidance or visit your site to help you install our fin tube machines. We welcome your inquiries!
Wound L LL KL G Fin Tube Machine Introduction:
The fin tube machine utilizes a stepless speed control system to regulate the fin tightness, ensuring the fins are tightly wound onto the smooth tube without loosening.
A variable frequency motor adjusts the fin spacing range (2.3~6mm), resulting in uniform and highly accurate fin spacing.
The transmission system uses a lead screw and rolling mechanism to drive the carriage in a continuous cycle. The gearbox employs a self-developed forward and reverse drive system.
Production types: Carbon steel pipes, stainless steel pipes, copper pipes
Finned tubes: G-type/L-type/LL-type/KL-type/KLM-type; copper-aluminum finned heat dissipation tubes.
Embedded type: Using disc-shaped blades, the tube is grooved to a depth of 0.35~0.4mm and a width of 0.5~0.55mm; aluminum (copper) fins are wound into the grooves and pressed tightly by a pressure roller next to the blade, ensuring the aluminum (copper) fins are firmly embedded in the copper or steel pipe.

Main Structure of the Equipment:
The bed of the Wound L LL KL G Fin Tube Machine is mainly constructed from welded steel plates. It consists of a worktable, automatic feeding system, precision lead screw drive, circulating cooling system, electrical system, and gearbox.
Wound L LL KL G Fin Tube Machine Bed and Worktable
The machine bed is a fully welded structure, subjected to secondary tempering treatment and remains deformation-free during vibration. The worktable features precisely machined, rationally arranged components for height adjustment, including forming wheels, pressure plates, pressure shafts, cutter heads, pressure rollers, and embossing wheels.
Feeding Mechanism
G Embedded Fin Tubes Finning Machine features pneumatic clamping and precision screw drive;
The clamps are adjusted to ensure consistent positioning for different pipe diameters.
Electrical System
The Wound L LL KL G Fin Tube Machine uses Japanese Mitsubishi electrical components.
Cangzhou Datang Steel Pipe Co., Ltd. has a five-person elite R&D team. This team includes:
(1) Two mechanical designers (with postgraduate degrees) responsible for mechanical drawing;
(2) One electrical engineer (with a bachelor’s degree) responsible for equipment electrical programming; and
(3) Two assembly technicians (proficient in reading blueprints) responsible for assembly and debugging.
1.G-type (Embedded) Finned Tube
Finned Tube Machine Operating Procedures
First: Connect the power supply, turn on the touchscreen, start the motor, manually move the carriage back to its original position, and then switch to automatic mode.
For G-type (embedded) machines: Press the clamping button, turn on the cooling motor, then press the forming button and the cutting button. The fins will be formed through the embedding process. The operation is complete.
2. L (LL) Type Fin Tube
Start the clamping button, turn on the cooling motor, adjust the copper (aluminum) folding width, adjust the pressure plate for tightening, start the operation button, and the fin forming is completed.
3.KL (KLM) Type Finned Tube
Start the clamping button, turn on the cooling motor, adjust the copper (aluminum) flanging width, adjust the pressure plate for tightening, start the start button, form the fins, and start the embossing wheel button. Operation complete.
