The features of LG20 Series two-roller cold pilger mill :

1. The main conveying system is with V belt which can make sure equal force , creditable and stable function .


2. The adoption of ring groove roller is to realize long term rolling . Big rotation angle of roller , longer ring type working stage and increased length of deformation zone lead to the uniformity  of metal deformation during the rolling . At the same time , it can increase feeding volume and improve the quality of the final processed pipe .

3. The rolling mill adopts edge feeding way removing the mandrel comparing to the side feeding . The exact location of mandrel on the deformation zone and short rolling line not only  suit for rolling long tube billet but also improve the roller’s efficiency .

4.Electric-control feeding and discharging way improve the working efficiency .

5. It is easier to replace the roller and more convenient to maintain based on the open rack .

6. Twin-wire feeding way realize the stable feeding.

7. To tighten with hydraulic mandrel lowers the labor strength .

8. The Mairtai type rotary feeding wau is precise , stable and reliable .
