Strengthening range per pressure vessel analysis method
Thread Content
Hello everyone: I would like to ask regarding section 6.6.1, when using analytical methods to calculate reinforcement for large openings, what is the range of reinforcement dimensions that must be satisfied for the overall reinforcement of cylinders or nozzles? Here, does the value l referring to the distance on the cylinder body mean only the distance in the axis direction of the cylinder body, or in all directions? Is it possible to use local thickening instead of thickening the entire tube section?
First question: As specified in the standards, the analysis method is applicable to radial nozzles. So there is no issue in the direction you’re considering at all; for example, when using local reinforcement for the cylinder, it definitely involves thickening the entire circumference of the cylinder within the area that needs reinforcement. Second question: Of course, otherwise there would be no first question.
