PRODUCT CENTER
Precision steel pipe is a kind of seamless steel pipe with high precision and high brightness produced by cold drawing or cold rolling process. Its inner and outer diameter size can be accurate to 0.1mm, in order to ensure the bending and torsional strength is the same, light weight, so it is widely used in the manufacture of precision machinery parts.
