Hi thaks for your answer.
The skatch is only to illustrate
The conection of the flange to the shell and to the stubend
From the point of view thermal stress in zone1.
Regarding the id of the shell,
It equals to the id of the inconel 800 ring 1114 mm.

Dear expert
I need to design a pressure vessel
Design pressure is 13.5 barg @ 350°c (195 psig@650°f)
My main concern is the body flange connection.
I have 2 option..
one :
is the to do an overlay with alloy 82 to the body flange 115 mm thk (about 5 mm thk overlay)
Second:
is to weld inconel 800...
Dear experts ,
Appreciate your answers.
Yes you all right ,we have a lot of 316l wire (gmaw 316lsi).
How can i Ensure that the weld meets the required mechanical strength and ductility criteria for the pressure vessel application.

Dear dekdee,
Thaks for your answer.
My client doesn’t care if the weld wil be made of 316l or 308l , it’s my responsibility as a designer.
I am asking it from a metalorgical welding point of view deu to the fact that it’s a pressure vessel working in elevated temperature.

Dear experts,
As far as I know when welding 304L to 304L the filler metal should be 308L.
My question is : can I weld 304L to 304L with filler metal 316-L ?
It’s a pressure vessel working in a full vacuum and + 0.7 barg at 250 ºc.
Material inside the vessel is not corrosive and suitable both...
Hi,
Very Critical.
The half pipe jacket has 2 roles
1.act as a stiffiners to hold full vaccum in the 904-l vessel
2.to hold the 6 barg pressure inside the
304-l half pipe
The welding connect the half pipe 304-L jacket to the 904-L vessel

Hello everyone
I need guidance in choosing a welding material for welding
Half pipe jacket reactor .
The reactor made of 904-L and the half pipe jacket made of 304-L(Contains steam at 160 °c)
What is the recommended welding material 904-L or 304-L
Thanks

Hi to all,
I need to design a stainless steel pressure vessel with carbon steel lugs Ring Girder .
Usually when design lug on a vessel it is possible to add a pad,
But in lugs Ring Girder I cannot find any guidance how to calculate the pad.
I have search Bednar
I use compress and pvelite, both...
hi rajout,
thanks .
if you choose in "lug type" the right image (lugs Ring Girder or gussets with continuoes top ring ), you can see that "optional pad parameters" is blocked.
