Type of longitudinal joint (e.g., Type 1, 2, 3, 4, 5, or 6) per Table UW-12. In case of brazing,explain type of joint per Figure UB-16. If seamless, indicate joint type as S, E for electric resistance welded, and W for autogenously welded.


UW-12
(d) Seamless vessel sections or heads shall be considered equivalent to welded parts of the same geometry in which all Category A welds are Type No. 1. For calculations
involving circumferential stress in seamless vessel sections or for thickness of seamless heads, E = 1.0 when the spot radiography requirements of UW-11(a)(5)(-b)
are met . E = 0.85 when the spot radiography requirements of UW-11(a)(5)(-b) are not met, or when the Category A or B welds connecting seamless vessel sections
or heads are Type No. 3, 4, 5, 6, or 8 of Table UW-12.

筒体是无缝管，type S中标准哪里定义的，是0.85还是1.0？

If seamless, indicate joint type as S 找到S的定义了， 是搭接焊缝， 焊缝系数该到1.0吗？

谢谢楼主分享的好资料

无缝管 type S, 如果是搭接焊缝，Eff.为1， 如果是对接焊缝，Eff.为0.85
