Flow Chart
Standard flow chart of 2018 new Welding Plant Stainless Steel  Easy Operate Pipe Making Machine :

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
