ASME SEC.Ⅷ, DIV.1中，对焊法兰与接管的环向焊接接头是B还是C

请教下各位，ASME SEC.Ⅷ, DIV.1中，对焊法兰与接管的环向焊接接头是B还是C类？谢谢！

ASME BPVC SEC. Ⅷ, DIV. 1 中，对焊法兰与接管的环向焊接接头是 C 类。见：
UW-3 WELDED JOINT CATEGORY
------
(c) Category C. Welded joints connecting flanges, Van
Stone laps, tubesheets, or flat heads to main shell, to
formed heads, to transitions in diameter, to nozzles, or
to communicating chambers66 any welded joint connecting
one side plate67 to another side plate of a flat‐sided
vessel.
这是国标与美标的不同之处。

C类！！！！！！！！！！！！！！

C类焊缝，跟GB150不一样

B
SEE Figure UW-3, PP111

真的么？？我看错了吗？？

了解学习了                     

是C类，跟GB150不一样，150中对接都是AB类，而ASME中是根据焊接接头位置划分接头类别的，C类中分为角接和对接，一般的高颈法兰的对接焊缝就是C类中的对接焊缝
