Cold Rolled High Precision Seamless Steel Pipes

Cold Rolled High Precison Seamless Steel Pipes,have bright and smooth surface with high precision tolerance.The tolerance of OD and ID can easy control to -/+0.1mm,even -/+0.05mm.So they widely used in produing high precision machine parts,fittings of car and motorcycle.

Cold Rolled High Precision Seamless Steel Pipes

Because of the bright and smooth surface of pipes,it can save energy during machinery process.So we can do polish and hone for the pipes.Then the pipes also have widely use in hydraulic cylinder,bearing sleeve and anchor rod.Below is the pipes after honing and polish.
