Dear Sir,
For ASME Div 1, normally we apply 30° for the bevel angle and 45° for Div 2.

How about PD 5500? 30° or 45°.

Thanks.

Regards,
Lee

Hello Lee

PD 5500 has a wealth of welding geometry details in its Annex E. There is so much information there, that it would be impossible to describe the illustrations in the space allotted on this forum.

Like AMSE VIII, Division 2, PD550 allows high design stresses (higher than division 2 in many cases), so generally all welding has to be full penetration. Try to get sight of a copy of PD500, as it is very informative. It is really necessary reading when the design of the vessel is being put together.

Ray,
I am sorry because my question is a little bit misleading. My question is not about welding bevel. I am asking the bevel angle for the FVC nozzle barrel to the nozzle neck. If you refer to PVElite on nozzle data, it is regarding bevel height on pad/hub section (if we choose hub type self-reforcing). Hope this time the question is clear.

Regards,
Lee

Dear Sir,

In a brief review of the Design Section 3 in PD 5500:2003 it does not appear that this section of the Code requires a certain bevel angle as Division 2 does. I would however read this section of the 5500 Code carefully as there may be a requirement for the height of the thickened section.
