Which dimension i will take.shall I consider B-C for thickness measurement in this chart.20 x 2 sch 40 is the dimension my weldolet means which NPS I have consider in the chart?20 or 2

Dear pennpiper, How can i calculate the thickness any formulae is available?

Dear Friends, I am having station piping work in pipeline.the piping system do not have PWHT.I am having 2 question inthis case 1.I qualifed the WPS with GTAW+SMAW upto the maximum thickness of 18.7 mm.My run pipe thickness is 15.09vmmm maximum.so i dont have any propblem in thickness...
