B16.5 ed 2003 shows in top of Table 5, page 64, the slip-on RTJ flange and is listing the 4", 1500# flanges details, including the R39 groove number...

RE: Silp On Flange with RTJ
ASME B16.5-2003 Tables 20 and F20 (Dimensions of Class 1500 Flanges) list dimensions for slip-on flange up to NPS 2 1/2" only. Therefore, a 4"-1500# RTJ SO flange is not a "standard" B16.5 flange.

What do you expect me to find by turning the page? Does your copy of ASME B16.5 have "B" and "Y" values for slip-on flanges beyond NPS 2 1/2" on Table 20?
Have you looked at the sketches above Table 20? What does it say for slip-ons? Doesn't it say...Slip-on Welding (NPS 1/2 to 2 1/2 Only)?
