Interpretation: VIII-1-89-227

Interpretation: VIII-1-89-227

Interpretation: VIII-1-89-227

(OP)
According to this interpretation if I have smls pipe and a bolted joint at each end welded to the shell with a full penetration corner joint a JE = 1 is permitted.

What if my weld attachments on both ends are loose type flanges (slip on flange / double fillet)? Can I still use a circumferential and longitudinal E = 1 as stated in Interpretation: VIII-1-89-227?


Thanks,

RE: Interpretation: VIII-1-89-227

Yes.  But ensure that the external fillet on the SO Flange is big enough to meet ASME requirements: leg lenght of 1.4 x pipe wall / fillet throat = pipe wall.

Additionally, this weld not being a butt-weld, no RT will be required.

Does the same rule apply if I have wld pipe such as SA-312 304 Wld? Or is this only for Smls pipe shells?

RE: Interpretation: VIII-1-89-227

Same in ASME pipe Codes - B31 series; B31.1, B31.3, etc.
