冷拔精密钢管是一种通过冷拔或热轧处理后的一种高精密的钢管材料。由于精密钢管内外壁无氧化层、承受高压无泄漏、高精度、高光洁度、冷弯不变形、扩口、压扁无裂缝等有点，所以主要用来生产气动或液压 元件的产品，如汽缸或油缸，可以是无缝管。
Cold-drawn precision steel pipe is a kind of high-precision steel pipe material after cold-drawn or hot-rolled treatment. Because the inner and outer walls of the precise steel tube have no oxide layer, withstand high pressure and no leakage, high precision, high gloss, cold bending and no deformation, flattening and crack, etc., it is mainly used to produce products of pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless tubes.
主要特点：钢管内外壁无氧化层，承受高压无泄漏，高精度，高光洁度，冷弯不变形，扩口、压扁无裂缝。
Main features: There is no oxide layer on the inner and outer walls of steel pipes, withstanding high pressure and no leakage, high precision, high finish, no deformation in cold bending, no cracks in flattening and flattening.
