Working Flow:

Raw material (steel strip coil) →uncoiling→shear and butt-welder→material accumulating→passively leveling→forming machine
→high frequency welding →remove the burrs outside→cooling →sizing machine→straightening→fixed length cutting →run out table
→finished tube
1. Double side uncoiler
Uncoiler is the important equipment in steel pipe making line, it's function is to support and expand the strip coil, so strip can enter into
machine for roll forming. Strip coil can be expanded by hydraulic and uncoiler can be rotated forward and reverse. Strip expanding speed
can be adjusted, braking device designed with pneumatic cylinder to press the brake rubber block, safety and reliable

5	Weight of steel coil	Maximum 1.6 Ton for each side
6	Brake type	Pneumatic disc brake

2.Auto Shear and butt-welding machine
  It"s function is shearing the head and the end of the steel strip, cutting of the irregular part then welding two steel strip together,
Polishing the welding seam,enter into the accumulator,so the line can working continuous.

No.	Item	numerical value
1	Thickness of steel strip	0.5~3mm
2	Width of steel strip	40~120mm
3	Shear method	Pneumatic shear
4	Frequency converter	Delta

Cold Saw:

It is cold cutting saw,pipe end is smooth and non-distortion.the length of burrs after cutting is lower than 0.2mm,Leave out the process of chamfering,no need chamffering machine, it will also reduce the cost in the future,low rotation speed with deep  feeding,

Saw blade with a low speed ,so it won"t damage worker when saw blade is broken when producing,the noisy is small, Design saw blade
back quickly when emergency stop or suddenly power off. So saw blade will not broken.
