由于生产的需求，和降低生产与制造的成本的缘故，许多客户由原本的冷拔无缝钢管采购改为精密钢管。下边就咱们就来理解下精密钢管的优点和劣势：精密钢管优点：
Due to the demand of production and the reduction of production and manufacturing costs, many customers have purchased precision steel tubes instead of cold-drawn seamless steel tubes. Next, let's understand the advantages and disadvantages of precision steel pipe: the advantages of precision steel pipe:
1、精密无缝管成型速度快，生产产量高。且不损坏涂层，可以制成多种多样的截面模式，以适用条件的需求。
1. Precision seamless pipe has fast forming speed and high production output. Without damaging the coating, various cross-section modes can be made to meet the requirements of applicable conditions.
2、冷轧工艺可以使精密钢管产生巨大的拉升变形，进而改善了精密钢管的屈服点。
2. Cold rolling process can make the precise steel tube produce huge pull-up deformation, and then improve the yield point of the precise steel tube.
3、精密钢管的准确度高，使用户减小了废物的产生。
3. Precision steel pipe has high accuracy, which reduces waste generation for users. 精密钢管劣势：
Precision steel tube disadvantage:
1、精密无缝管截面存在剩余应力，对精密钢管的总体和局部屈曲的特点产生影响；
1. Residual stress exists in the section of precision seamless pipe, which affects the overall and local buckling characteristics of precision steel pipe.
2、精密钢管的截面的自由扭转刚度比较低；
2. The free torsional stiffness of the precise steel tube section is relatively low.
3、冷轧精密钢管的成型壁厚较小，经受局部性的集中负荷运载的能力不足。
3. The cold-rolled precision steel tube has a smaller wall thickness and insufficient capacity to withstand local concentrated load.
