Pressure Vessel Design Parameter Table
Thread Content
May I ask whether in the design parameter table for pressure vessels, the welding factors, as well as the inspection ratios and grades for the cylinder and the head, are filled in separately? Please give some guidance; let’s learn from each other. Thank you
We usually don’t write them separately; if the two coefficients are not identical, a note is added or something similar. Generally, they are only categorized into A, B, and C, D
1# Night rain and cold: The welding joint coefficient in the design parameters table for pressure vessels refers to the welding joint coefficient of the longitudinal welds of the cylinder body
On this issue, different people have different opinions; as long as it is correct, that’s what matters!
What was said on the 3rd floor is not comprehensive; it should be Type A connectors. Including head joint seams.
We usually write them separately, because the weld coefficients used in calculations are not necessarily the same.
I think they should be separated; sometimes their levels are different, and when they’re the same, they can be placed together. Personal opinion, for reference only
We write them separately; sometimes the welding joint coefficient and the inspection ratio do not match
It’s simple: if they are the same, they stay together; if they are different, they separate. Do it in whatever way is most convenient
It can be different, but regardless of the amount taken, the flaw detection for the end caps is 100%; as for the qualification standard, it must meet or exceed the requirements for the longitudinal seams of the cylinder
