Regarding the scope of strength calculation for pressure vessels
Thread Content
Dear experts, where in the code for strength calculation of pressure vessels is it specified what range needs to be calculated? For example, there are relevant provisions in regulations or standards.
All pressure-bearing components need to be calculated; standard components are exempt from this requirement. For specific details, refer to standards such as GB150 and 151
GB150 GB151, etc
It depends on the standards required for your container; for imported ones, ASME compliance is necessary, while for domestically produced ones, standards such as HG, SY, SH, and GB apply
Everyone upstairs has explained very clearly that there are specific regulations for every type of pressure vessel; if you’re new, you can take a look at previous calculation documents
Logically, everything on the equipment that is not standard, as well as those standard components selected in accordance with strength requirements, along with the structures and parts for which exemption from calculation is specified in relevant technical standards and product standards, must all be taken into account in the calculations.
Within the first fitting: if it is threaded, then the area up to the first threaded connection is included in the calculation； If it is a flange, then the area up to the first flange is included in the calculation range ；
