Our factory manufacture ERW tube mill line includes forming, HF welding, cooling and sizing sections with Turks Heads for precision calibration. It offers three forming modes: W Forming for high accuracy and long service life; FF/FFX slashing roller cost and change time; DFT supporting roll-free size switching with one-click recipe adjustment. The quick change system realizes offline roller setup to sharply reduce production downtime.

Accumulator For ERW Mill Line, ERW Tube Mill Line

Horizontal Table/Spiral Accumulator For ERW Pipe Mill,Tube Mill Strip Storage Horizontal Accumulator

Horizontal & spiral strip accumulators install between shear-end welder and forming mill on ERW pipe lines. They reserve steel strip to feed downstream mill continuously during coil change, strip cutting & butt welding, preventing line stops. This vital auxiliary ensures non-stop ERW tube production, reduces downtime, and improves line efficiency, product yield and overall productivity.

ERW Tube Mill Line, Shear End Welder For ERW Mill Line

Automatic Shear End Welder for ERW Tube Mill Line,Continuous Strip Shear Butt Welder Unit

The shear end welder we supply serves as vital front-end auxiliary equipment for ERW and OCTG welded pipe production lines. It precisely trims deformed and uneven edges of old and new steel strip coils, then completes automatic alignment and butt welding to splice strips tightly. The joined steel strip enters the accumulator, eliminating line stops during coil replacement and sustaining steady, non-stop pipe fabrication.

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.
