Webbpipe with diameter to thickness ratio 30 according to ASME B&PV is 4 MPa, when using ASME code case 2286 critical pressure value increases to 5.3 MPa and by using FEA the critical pressure value is 11.4 MPa. Although the ASME code case 2286 procedure is valid in ASME B&PV code but it is not allowed to be used in ASME B31.3 code!? .

Many codes such as B 31.3, B 31.1 and IBR give equations to calculate the minimum allowed wall thickness based on the pressure of the material within the pipe. WebbPipe was originally measured in inches. 100NB pipe works out to be exactly 4.5 inches (4.5 (inches) x 25.4 (mm/inch) = 114.3mm). That is why the outside diameter can’t be simple number like 100mm. There are regulations that govern the outside diameter (O.D) of pipe. So, to allow for different wall thicknesses in the manufacturing of pipe ... if you babysit do you have to pay taxes
