由於（yú）生產的需求，和降低生產與製造的成本的緣故，許多（duō）客戶由原本的冷拔無縫鋼管采購改（gǎi）為精密鋼（gāng）管。下邊就咱們就（jiù）來理解下精密鋼管的優點和劣勢：精密鋼管優點（diǎn）：
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、精密無縫管成型速度快，生產（chǎn）產量高。且不（bú）損壞塗層，可以製成多種（zhǒng）多樣的截麵模（mó）式，以適用條件的需求。
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、冷軋（zhá）工藝可以使精密鋼管產生巨大的拉升變形，進而改善了（le）精（jīng）密鋼管的屈服點。
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、精密鋼管的準確度高，使用（yòng）戶減小了廢（fèi）物的產生。
3. Precision steel pipe has high accuracy, which reduces waste generation for users. 精密鋼管劣勢：
Precision steel tube disadvantage:
1、精密（mì）無縫管截麵存在剩餘應力，對（duì）精密鋼管的總體和（hé）局部屈曲的特點產生影響；
1. Residual stress exists in the section of precision seamless pipe, which affects the overall and local buckling characteristics of precision steel pipe.
2、精密鋼管的截麵的自由扭轉剛度比較低；
2. The free torsional stiffness of the precise steel tube section is relatively low.
3、冷軋精（jīng）密鋼管的成型壁厚較小，經受局（jú）部性的集中負荷運載的能力不足。
3. The cold-rolled precision steel tube has a smaller wall thickness and insufficient capacity to withstand local concentrated load.
