Questions regarding Clause 3.2.2.2 of the large capacity regulations
Thread Content
Section 3.2.2.2 of the large-volume code is titled “Design of Weld Joints between Nozzles and the Shell,” and its content deals with the design of weld joints between the nozzles (flanges) of pressure vessels and the shell, as well as the weld joints of jacketed pressure vessels. . . . Is the jacketed pressure vessel mentioned a bit unrelated to the content of the title? The content of the 99 version of the regulatory specifications is acceptable; I don’t know why it was written that way. Could anyone explain it clearly?
The welding joint between the jacket and the cylinder body is classified as a \"welding joint between a pipe fitting and a shell\", adopting a fully penetrated structure.
The contents specified in the 99 version of the regulations are consistent with those of the nodes in version 150 of 1998, but this term used in the new regulations seems a bit forced.
The standards also have their shortcomings...
