精密管
精密管
精密管是一种通过冷拔或冷轧工艺生产的高精密度、高 光亮度的无缝钢管。其内外径尺寸可精确至0.2mm以内，在 保证抗弯、抗扭强度同时，重量较轻。
Precision tube is a kind of seamless steel tube with high precision and high brightness produced by cold drawing or cold rolling process. Its inner and outer diameter dimensions can be accurate to within 0.2mm, which is light in weight while ensuring bending and torsional strength.
