Precision steel pipe is a kind of high-precision steel pipe raw material after cold drawing or hot rolling. Because there is no air oxide layer on the inner and outer walls of precision steel pipes, it bears the advantages of high pressure without leakage, high precision, high smoothness, cold drawing without deformation, flaring, flattening without gaps, etc., so it is key to the manufacture of pneumatic or hydraulic parts. , Such as cylinders or hydraulic cylinders, can be seamless pipes or welded pipes. Its characteristics are: 1. The diameter is smaller. 2. High precision can be produced in batches. 3. The cold-drawn finished product has high precision and good process performance. 4. The total area of the steel pipe is more complicated. 5. The steel pipe has better characteristics and denser metal materials. 3. The cold-drawn finished product has high precision and good process performance. 4. The total area of the steel pipe is more complicated. 5. The steel pipe has better characteristics and denser metal materials.
Small-diameter steel pipes are small-diameter steel pipes, which can be called small-diameter steel pipes. Small-diameter steel pipes can be pided into: small-diameter seamless steel pipes and small-diameter straight seam steel pipes(also called electric welded). The diameter below 89 can be generally called small-diameter steel pipe. According to different manufacturing methods, it can be pided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, etc. Hot-rolled seamless pipes are generally manufactured on fully automatic pipe rolling mills. Its characteristics are: 1. The diameter is smaller. 2. High precision can be produced in small and large quantities. 3. The cold-drawn finished product has high precision and good process performance. 4. The total area of the steel pipe is more complicated. 5. The characteristics of the steel pipe are superior, and the metal material is denser.
