LD-330 Cold Pilger Mill for Steel Pipe

LD-330 Cold Pilger Mill   The LD-330 cold rolling mill (Pilger rolling mill) is a precision rolling equipment for cold processing of large-diameter seamless steel pipes, suitable for carbon steel, stainless steel, alloy steel pipes, etc.   The equipment adopts a reciprocating cold rolling process, producing pipes with high precision, uniform wall thickness, and smooth surface. It features a robust structure and stable operation, and is mainly used in the production of large-diameter precision seamless pipes in industries such as petrochemicals, engineering machinery, and pressure vessels.   No.    Description Unit Tube Cold Rolling Machine Model LD-330 1  Hollow size Outside diameter mm φ173～350 Wall thickness mm 5~35 Length m ≤8 2 Tube size Outside diameter mm φ160～330 Wall thickness mm 3.5~33 Length m ≤15 3 Max. elongation ratio of rolling   It depends on the material 4 Stroke rate of roller carriage str./min. 15～30 5 Stroke length of roller carriage mm 140…
