May I ask why some drawings include tables of allowable stress loads, while others do not?
Thread Content
What is this allowable stress load table, and what does it represent? When is it necessary to write it down?
Is the poster referring to the allowable stress load table for pipe fittings?
Well, the allowable load table for the nozzle also shows force and torque values, but it’s hard to understand
To calculate the nozzle load, this table must be included; generally, this is done in accordance with Appendix D of SH3074, or as specified by the project requirements
There are no mandatory standards for domestic drawings, while some foreign drawings do have such requirements. This is mainly to provide a force and torque that the fitting on the container can withstand; it is important not to apply excessive force during installation to avoid damaging the container
This is likely the calculation parameter provided by the process for computing the local stress at the pipe outlet (using WRC107, WRC297, etc.).
It mainly calculates the stress at the pipe outlet; sometimes, when the stress on the connection pipe is not sufficient, a reinforcement ring needs to be added.
Indicates the forces and moments acting on the pipe outlet (X, Y axes, etc.)； For calculating the local stresses in the shell at the pipe opening, etc., the local stress calculation function in SW6 can be used for verification ； If required by the project, it must be indicated on the drawings
