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→ spraying cooling →sizing machine → straightening→ fixed length cutting →run out table→ finished tube

Each part of machine introduction

1.Single side hydraulic uncoiler

The function of this part is to separate the steel strip coil and strip will enter into 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 uncoiler , 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	Φ450mm～Φ550mm
Outer diameter of steel coil	Φ1000mm～Φ1600mm
Width of steel coil	H280mm～H570mm
Wight of steel coil	≤8.0Ton

2.Simple type shear and butt-welding machine

The function of this part is using hydraulic knife to cutting the irregular part in the front and end of the steel strip,welded by hand.
