Greatly improve the quality of steel surface, increased finishing rate of product.
Increased the product specification can be produced in the line of seamless mill.
Reduced the roll changing times of perforating machine and pipe mill.
It can roll the pipe which length is less than 160m.
Reduced tubular billet size is conducive to production management.
