Lifting Lug – WRC Calculation

Introduction: All directly welded parts to the pressure vessel like lifting lugs, support lug, trunnion etc. need to be checked for WRC 107/537. All related calculations are carried out in PV Elite once given proper inputs. In some cases, it is not possible to build such directly welded parts in PV Elite due to software constrain. For example, adding lifting…

Flange Evaluation as per ASME B16.5 Pressure-Temperature Rating

Standard flanges for the nozzles is having strength identification by a dimensionless number which we called as a class. Class, followed by a dimensionless number, is the designated icon for pressure-temperature ratings: For Example:  Class   150   300   400   600   900   1500   2500 Pressure-temperature ratings are maximum allowable working pressures in bar units at the temperatures in degrees Celsius shown in…
