由於生產的需求（qiú），和降低生產與製造的成本的緣故，許多客戶由原本的冷拔（bá）無縫鋼管采購（gòu）改為精密鋼管。下邊就咱（zán）們就來（lái）理解下精密鋼管的優點和劣勢：精密鋼管優點：
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，生產產量（liàng）高。且不損壞塗層，可以製成多種多樣的截麵模式，以適用條件（jiàn）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、冷軋工藝可以使精密鋼（gāng）管產生巨大的拉（lā）升變形，進而改善了精密鋼管的屈服點。
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（guǎn）的準確度高，使用戶減小了廢物的產生。
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（cún）在剩（shèng）餘應（yīng）力，對精密鋼管（guǎn）的總體和局部（bù）屈曲的特點產生影（yǐng）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（jīng）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（lěng）軋精密鋼管的成型（xíng）壁厚較小，經受局部性的集中（zhōng）負（fù）荷運（yùn）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.
