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.
