    WALL THICKNESS CALCULATION FOR LARGE DIA PIPES

    I have 48" API 5L GR. X52 LSAW PIPE, Design temperature is 75 deg C, design pressure is 138 bars & corrosion allowance is 3mm. When calculated wall thickness using formula t= PD/(2SE+PY)I got result as Wall thickness = 70mm? Is that true? we can't find pipe with such thickness. What will be the...
