Discussion on the technical index of GB/T 8163-1999 seamless steel tubes for liguid service,make suggestions on organizing production of seamless steel tubes for liguid service.
综合论述了GB/T 816 3- 1999输送流体用无缝钢管标准技术指标 ,对输送流体用无缝钢管组织生产有一定指导意义。
The traditional method for measuring the geometric sizes of seamless steel tubes is mechanically and manually test on the both ends of tubes, which could not meet the requirement of modern industry for high accurate steel tubes .
无缝钢管几何尺寸的传统测量方法，是在其两端由人工进行机械式测量，它已远远不能满足现代工业对高精度钢管的要求。
