Welding pipe unit is a type of equipment used for producing welded steel pipes, usually including steel strip feeding system, welding system, cooling system, cutting system, and unloading system. The welding system usually uses high-frequency induction heating technology to heat the steel strip to the welding temperature, and then weld the steel strip into a tube shape through high-frequency current. The cooling system is used to reduce the temperature after welding to ensure the quality and shape of the pipes. The cutting system is used to cut the welded steel pipe into the required length. The unloading system is used to unload the cut steel pipe from the unit. Welded pipe units are widely used in industries such as construction, shipbuilding, automotive manufacturing, and petrochemicals.

5. Simple maintenance: The maintenance of Carbon Steel Tube Mill is simple, easy to operate and repair, reducing equipment failure rates and maintenance costs.
6. Energy conservation and environmental protection: The equipment adopts advanced energy-saving technology, reducing energy consumption and environmental pollution, and meets environmental requirements.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 stripAdvantage:

>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

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
