对于使用无缝钢管的朋友来说，For friends who use seamless steel pipes，还能够提高加工生产效率。Finding the right specification not only saves costs，往往只能凭借自己应用中无缝钢管的型号来定Often only use the model of seamless steel pipes in your own application.。Can also improve processing productivity。这就需要找接近型号来替代，But some friends do not clearly have a seamless steel pipe model produced by different manufacturers.：
