注：1、此表是GB/T9711-1997和APISL標準給出的最低（標準）試驗壓力，表中未列出的鋼級，管徑和壁厚的午夜精品影院的最低試驗壓力按下式計算並考慮標準對最高試驗壓力的限製，當采用GB/T9711.2-1999jf，除另有協議外，S中的係數為95%， 並規定D≤406.4mm，最大壓力為50MPa；D＞406.4mm，最大壓力為25M Pa。
式中：P-靜水壓試驗壓力（MPa）；S-標準規定最小總伸長應力（Rt10.5MPa）乘以標準所給係數；T-午夜精品影院壁厚（mm）；D-午夜精品影院外徑（mm）。
2、L210、L245鋼級D≤48.3mm午夜精品影院的試驗壓力是給定的。
其餘外徑和心中壁厚鋼試驗壓力是按注1的公式計算的。
3、按GB/T3091-2001生產的午夜精品影院應逐根進行水壓試驗，試驗壓力應符合表一規定。
