SA 182 Gr. F9 & Impact testing Per B31.3 Figure 323.2.2A
(OP)
I have a design using SA 182 Gr. F9 material for a sampling thermowell/quill that will consist of an SA 182 Gr. F9 flange and F9 bar. The bar will have a 1/4" diameter bore and the components will be full-pen welded. The customer has reviewed our weld procedure which has no record of impact testing and has submitted comments stating that the base metal thickness is limited by curve B of Figure 323.2.2A. I have been unable to see that this material is covered by curve B. Table 1A lists a minimum temperature rather than a letter code for a curve for SA 182 Gr. F9.
Am I missing something?

I agree and understand the importance and reasoning behind impact testing at service temperatures lower than minimum allowable per code. I'm trying to make sure that I can look at the code text, figures, etc. and understand what is being instructed by them. In this case, we have the customer and myself looking at the same code and coming up with different interpretations. I don't want to be the one who in misinterpreting. When I look at 323.2.2A and then go to Table 1A, I'm not seeing that SA 182 Gr. F9 is designated as being a curve B material. If the customer had simple said that I must impact test for temperatures lower than that shown in Table 1A, I would have no issue.
