由於生（shēng）產的（de）需求（qiú），和降低生產與製造的成（chéng）本的緣（yuán）故，許多（duō）客戶（hù）由（yóu）原本的冷拔無縫（féng）鋼管采購改為精密鋼管。下（xià）邊就咱（zán）們就來理解下精密鋼管的優（yōu）點和劣勢：精密鋼（gāng）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（xíng）速度快，生產產量高。且不（bú）損（sǔn）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管產生巨大（dà）的拉（lā）升變形，進而改善（shàn）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（mì）鋼（gāng）管的準確度高（gāo），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、精密無縫管截麵存在剩餘應力，對精密鋼管的總體和局部屈曲的特（tè）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（miàn）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、冷軋精密鋼管的成型壁（bì）厚較小（xiǎo），經受局部性（xìng）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.
