    鉗壓聲測管承受壓力計算公式方法

            一:以知無縫管鉗壓聲測管外徑規格壁厚求能承受壓力計算方法?。ㄤ摴懿煌馁|抗拉強度不同)

            壓力=(壁厚*2*鋼管材質抗拉強度)/(外徑*系數)

            二:以知無縫管鉗壓聲測管外徑和承受壓力求壁厚計算方法:

            壁厚=(壓力*外徑*系數)/(2*鋼管材質抗拉強度)

            三:鋼管壓力系數表示方法:

            壓力P<7Mpa  系數S=8

            7<鋼管壓力P<17。系數S=6

            壓力P>17。系數S=4
