ERW Tube Mill Line, Flattener
ERW Welding Flattener,Strip Leveling Machine for OCTG Tube Mill,Steel Strip Straightening Machine
The flattener machine our factory supply is a necessary auxiliary device for ERW pipe lines. It levels hot & cold rolled steel strips to fix camber, edge curl and warpage. Precise rolling ensures uniform flatness before forming, prevents strip shifting, reduces welding defects like seam offset and incomplete penetration, and stabilizes finished pipe dimensional precision.
ERW Tube Mill Line, Un-coiler
Single Drum Un-coiler
Our factory focus on ERW tube mill entry uncoiler,which features coil trolley automatic feeding and expandable mandrel unwinding structure to convey steel strips precisely into the flattener. Constant stable strip tension effectively prevents material blockages, delivers perfectly leveled blanks for subsequent forming, high-frequency welding and sizing processes, and guarantees reliable large-batch production of standard OCTG casing and tubing.
ERW Tube Mill Line, Un-coiler
Double Drum Un-coiler
Double drum uncoiler works as core inlet equipment for ERW welded pipe production lines, unwinding steel coils with the support of coil loading trolleys. The expandable mandrel prevents coil distortion, while matched driving and braking systems ensure stable strip feeding to the leveler, keeping constant tension and eliminating material jams to support precise forming, HF welding and sizing for OCTG casing, tubing and structural pipes.
