注：1、此表是GB/T9711-1997和APISL标准给出的最低（标准）试验压力，表中未列出的钢级，管径和壁厚的芭乐APP下载安装IOS在线的最低试验压力按下式计算并考虑标准对最高试验压力的限制，当采用GB/T9711.2-1999jf，除另有协议外，S中的系数为95%， 并规定D≤406.4mm，最大压力为50MPa；D＞406.4mm，最大压力为25M Pa。
式中：P-静水压试验压力（MPa）；S-标准规定最小总伸长应力（Rt10.5MPa）乘以标准所给系数；T-芭乐APP下载安装IOS在线壁厚（mm）；D-芭乐APP下载安装IOS在线外径（mm）。
2、L210、L245钢级D≤48.3mm芭乐APP下载安装IOS在线的试验压力是给定的。
其余外径和心中壁厚钢试验压力是按注1的公式计算的。
3、按GB/T3091-2001生产的芭乐APP下载安装IOS在线应逐根进行水压试验，试验压力应符合表一规定。
