    注:1、此表是GB/T9711-1997和APISL標(biāo)準(zhǔn)給出的最低(標(biāo)準(zhǔn))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(biāo)準(zhǔn)對最高試驗壓力的限制,當(dāng)采用GB/T9711.2-1999jf,除另有協(xié)議外,S中的系數(shù)為95%, 并規(guī)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(biāo)準(zhǔn)規(guī)定最小總伸長應(yīng)力(Rt10.5MPa)乘以標(biāo)準(zhǔn)所給系數(shù);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(chǎn)的鋼管應(yīng)逐根進行水壓試驗,試驗壓力應(yīng)符合表一規(guī)定。
