Product Description

     Cold rolled seamless pipe is a precision seamless steel pipe with high dimensional accuracy and good surface smoothness, used for mechanical structures and hydraulic equipment.Cold rolling has higher dimensional accuracy than hot rolling.
      Advantages:
       Fast molding speed, high output, and no damage to the coating. It can be made into a variety of cross-sectional forms to meet the needs of usage conditions; Cold rolling can cause significant plastic deformation in steel, thereby increasing its yield point.

    The promotion and application of high-precision cold-rolled precision steel pipes can save steel, improve processing efficiency, and save energy. The so-called high-precision cold-rolled seamless steel pipes refer to strict inner and outer diameter dimensional accuracy (tolerance range), good inner and outer surface smoothness, roundness, and straightness, which can greatly save machining hours, improve material utilization, and also help improve product quality.
