  3. Production working flow Raw material (steel strip coil) →decoiler→flattening→powerful leveling →shear and butt-welder→horizontal type accumulator→passively leveling→ forming machine→high frequency welding →remove the burrs outside→eddy current flaw detector→spraying cooling →sizing machine→straightening→fixed length cutting →run out table→finished tube   4. Each part of machine introduction   1. Uncoiler The function of this part is to separating the steel strip coil and become to the raw material to roll forming . The steel strip coil will be brought in to the below of the double-drill uncoiler,  hydraulic cylinder support the steel strip coil to the centre of the double-drill uncoiler , double-drill uncoiler began moving to hold the steel strip coil, coil car  fall off by hydraulic cylinder and go back.

Structure type	Double-drill automatic decoiling
Inner diameter of steel coil	Φ500mm~Φ600mm
Outer diameter of steel coil	Φmax:1800mm
Width of steel coil	H520mm~H860mm
Wight of steel coil	≤12T

  2. Flattening and powerful leveling machine The function of this part is to separating the front head of steel strip on the uncoiler,also reversed bending the steel coil head to adjusting it’s character of inner curl. Steel strip will enter into the flattening machine by dynamic rubber roll.  Flattening machine equipped with one set of pinch roll device and five roll leveling device ,there is one pairs centring device in front and behind it. Flattening and powerful leveling machine.   5. Details pictures
