Process flow cards for three types of containers
Thread Content
Do all the pressure-bearing components of the three types of containers need to be included in the process flow card? I only know that for Class 1 and Class 2 containers, it is sufficient to specify only the main pressure-bearing components; I hope those with more expertise can provide further guidance
Do you mean that angle steel, rebar plates, and things like that are also needed? It doesn’t seem to be a mandatory requirement
I misread it; you were referring to the compressed element. I’m not sure about this
It is mainly for quality control reasons. If you have other traceability documents as proof, that will also work; in fact, many of these documents can be placed on a single page. There are also requirements regarding quality assurance manuals
It’s mainly some small flanges and small pipes (with a diameter of less than 250 mm). Should they be included? If so, will each piece take up one sheet of paper?
We all use process cards specific to the main stressed components (one card per component); for flange connections smaller than 250 MM, one general-purpose process card is sufficient.
