High Duty φ89mm OCTG Pipe Straightening Equipment,ERW Pipe OCTG Straightening Machine

1.Straightness Accuracy

Regular type: ≤ 1mm/m

Precise type: ≤ 0.7mm/m

2.Anti-collision Design:Equipped with a quick bypass function to effectively avoid equipment collision.

3.Automatic Adjustment:Realize automatic height adjustment of straightening rollers; support automatic storage, retrieval and adjustment of roller height and angle parameters.

4.Stress Relief & Permanent Straightening Effect:Eliminate residual internal stress of steel pipes to prevent secondary bending of finished straight pipes.

5.Rotary Straightening Technology:Adopt rotary straightening mode to unify overall pipe curvature and efficiently correct bent pipes.

6.Optimized Roller Layout:Dual layout of aligned & misaligned straightening rollers, greatly improving pipe straightness and ovality control.

7.Wide Adaptability:Adapt to different steel pipe conditions,pipe straightening machine from our factory could meet different material yield strength, wall thickness, production line speed, as well as online and offline working modes.

8.Roller Configuration:

It can be a 3-upper 3-lower straightening roller ratio and it also could be a 3-upper 4-lower straightening roller ratio,the 3-upper roller are equipped with a worm gear adjustment structure which can adjust the specifications of the steel pipe and the 4-lower rollers contain one passive roller with 3 active lower roller.According to your request we also could supply a 10-roller straightening ratio structure of 5-upper 5-lower.

9.Professional Design & Calculation:Integrated functions of straightening roller profile design and straightening force intelligent calculation.
