[MW:1843] RE: 1841] Re: 1838] Fabricated Stiffeners

Devang,

As per ASME it is no where specified for external pressure design to use
the staggered intermittent weld to fabricate the stiffeners. Hence, in
my opinion it should not be used. You have to meet the required moment
of inertia for the provided section. It is advisable to fabricate the
stiffener with continuous welding only.

Thanks, Somesh,

Yes, you are write but my question is can we do staggered intermittent
weld
to fabricate the stiffeners?

ASME Sec. VIII Div-1 told about the stiffeners to shell welding only.

Dear Devang,

Fabricated stiffeners can be used in external pressure design of shell
of
pressure vessel as per ASME Sec. VIII Div.1. You can refer UG -29 , Fig.
UG 29.1 , UG-30 & Fig. UG-30 of ASME Sec. VIII Div.1 for more details on
the acceptable method of attaching stiffener rings

can we use fabricated stiffeners in external pressure design of shell of

pressure vessel?

If, yes than please tell, can we use staggered intermittent weld to
fabricate T or Angle?

Please reply.
