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，管径和壁厚的钢管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-钢管壁厚（mm）；D-钢管外径（mm）。
2、L210、L245钢级D≤48.3mm钢管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生产的钢管应逐根进行水压试验，试验压力应符合表一规定。
