ERW Tube Mill For Carbon Steel Tubes

Longitudinal Welded Tube Mills

Designed to meet the individual requirements of our customers, our Tube Mills comprise of the following parts:

• Fully mechanized entry line comprising of:
  • Uncoiler
  • Coil Opener
  • Shear and End Welder
  • Fully automatic Horizontal Accumulator
• Highly efficient and accurate double output reduction and distribution gear boxes for mill drive
• Forming Mill
• Welding mill with Solid State Welder
• Sizing Mill
• Fully automatic NC controlled Flying Cut-off (both Friction/Cold saw)
• Ergonomically designed Roll Out Table with two side ejection

Highlights

• They include a fully mechanized entry line with hydraulic Shear & End Welder and fully automatic Horizontal Spiral Accumulator for totally stress-free strip accumulation.
• Highly efficient and accurate helical reduction & distribution gear boxes to drive the mill. This reduces power consumption as compared to worm gear boxes.
• Robust 2, 3 and 4 roll type squeeze roll assemblies for a precise control of weld parameters and to reduce the size of rolls to enhance the HF Welder efficiency.
