Thickness of the steel pipe

The thickness and breadth of the steel strip is determined according to different pipe diameter and ring stiffness class requirements.

加强钢带的厚度与宽度根据管材直径、环刚度要求不同而分别设计确定。

After checking the pipe wall thickness, pipe stress and safety factors this batch of steel material has still complied with the requirements, while safety Surveillance should be enhanced.

通过管道壁厚、管道应力、安全系数的校核，表明该批钢材仍符合要求，但要加强安全监督。

In the evaluation of steel pipe quality, the pipe appearance, the weld appearance, the pipe wall thickness, the defect types and sizes, and the pipe materials are selected as the evaluation factors.

在钢管质量评价过程中，选取了钢管外观、焊缝外观、管道壁厚、缺陷种类及尺寸、管道材料作为评价因素集。
