Automatic Coil Slitting Machine High Precision Speed Max 100 M / Min
Φ60 Tube mill Line
High‐frequency welded tube mill line is designed to produce round tube diameter of Φ12.7 –Φ63.5mm, and wall thickness of 0.8 ‐3.2 mm.
This line utilizes roll forming to process steel strip into various shapes.
Using high frequency induction heating, this line is capable of producing section material of various diameters and sizes by squeezing weld seam together into closed shape.
The application of advanced aperture technology, PLC automatic control system and British Eurasia Digital speed‐regulating unit ensure that the production line works reliably and operates and maintains easily.

Step 1: Un-coiler
Function: support rolled plate and strip tension for erw pipe mill production line, by the frame, main shaft, increases of drum, brake.
There are 3 types: pneumatic, hydraulic and manual.
Step 2: Shear & butt-welding
Function: Shear the end of each strip coil, then welding them together, so that pipe making welding machine line can be continue production.
2 Types: Automatic & manual
Step 3: Vertical Accumulator
Function: storage strip to keep continue production for the machine to make metel tube.
Type: Vertical
Advantage: easy to operation, low investment. special for small size and light wall pipe
Disadvantage: less storage capacity, crease.
Step 4: Horizontal Accumulator
Function: storage strip to keep continue production for the Round Square Pipe Making Machine Production Line.
Type: Horizontal
Advantage: Large capacity.
Disadvantage: more expensive than vertical type
Step 5: Forming section
Function: forming the tube from strip
Advantage:
> Advanced forming technical
> One-stage molding platform
> Reliable quality gear box
> Siemens Beide motor
Step 6: High Frequency Welding
Function: Welding the pipe , different thickness & diameter, the power of the HF welding machine welder
Our advantage: We choose the China best welder: Sanyi brand.
Step 7: Sizing section of pipe making machine
Function: sizing the tube to precise size
Advantage:
> Advanced sizing technical
> One-stage molding platform
> Reliable quality gear box and Siemens Beide motor
> High precision, low error of the pipe size
Step 8: Flying saw
Function: cutting the tube mill line tube to right length.
Advantage: easy to operation, low investment.
Disadvantage: loud, cutting section generates burr.
Step 9: Cold saw cutting of ERW tube mill line
Function: cutting the tube to right length.
Advantage: No noise, no burr cutting precision and cross section .
Disadvantage: the price is 4 times of ordinary flying saw.
Step 10: Run Out Table.
Function: run out the pipe, packing the pipe for tube making machine
Type: Automatic or manual
