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,管徑和壁厚的鋼管的最低試驗壓力按下式計算并考慮標準對最高試驗壓力的限制,當采用GB/T9711.2-1999jf,除另有協議外,S中的系數為95%, 并規定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)乘以標準所給系數;T-鋼管壁厚(mm);D-鋼管外徑(mm)。
2、L210、L245鋼級D≤48.3mm鋼管的試驗壓力是給定的。
其余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生產的鋼管應逐根進行水壓試驗,試驗壓力應符合表一規定。
