Flanges: 2016 #41

Question: What flanges classes can be used in a 200 F & 1,450 psig flowstream (SF = 2, or 2,900 psi)?

I just glanced at the cover TOC and scanned to Facilities (FAC). "Flange Ratings" was 8 FAC 7. Less than 60 seconds to size up the problem and find my page with all the needed tables. Note these tables are also in HS3-356 (tab this page).

Answers (C) and (D) gave API Class 2000; 2,000 psi. So they are eliminated.
ANSI Class 900?  2,025 psi. So it can't be (A) either. This has taken me two minutes.
API Class 3000? 3000 psi. ASME 1500? 3,375 psi. So we have a winner, (B).

Less than 3 minutes; I take another minute to review for tricks, finding none, I move on.

Note on the new EBT exam they can merely provide the needed charts, much like the Guidebook does.
