What value should be used as an input for "allowable shear stress" for anchor bolts when designing a saddle for horizontal vessel in compress? I am using SA-193 B7. The default values is 15000 psi. I believe this value is for Sa-307, and it is allowable tensile stress. What is the allowable...

From my experience, usually the Vendor provides the base plate with the equipment during purchase (as long as it was requested by the Client). My question is: how do Vendors usually size and design base plates? 1- is there a standard that they reply on: API, ASME, AISC? 2- is there a...

Thank you for the reply guys. This surely is a design that needs some one with structural engineering experience, as i am not familiar with this at all.

Does any one know how to design a base plate support or a skid however you wanna call it) for a compressor motor. It has to be made out of structural steel. The motor is about 5000 pounds. I have no idea how to do this. Do you guys have any suggestions?

The Y value for seating load is too big for the two m16 bolts that i have. i only have 2 m16 bolts to keep the flage tight, and they fail when it comes to seatign loads.

I meant to say that existing design came without a gasket. it is a 12" x 2.5" rectangular flat flange with 2 x 10mm holes in the middle. The blind cover will only see the design pressure through the 2 x 10mm holes. it is a bit of a unique design.

Thanks for the bulletin, I found out about TAYLOR buletins today, when I tried to model this in Compress.

Thanks for the reply. The existing design came with gasket, operating condition changed so we have to design a new rectangular blind flange. The liquid is very viscous, so hopefully it won't leak.

I am trying to blind a rectangular flange to seal a pressurized fluid. There won't be a gasket in between the flange and the blind. My surface finish is 16 micro inch. I have calculated the static load based on the fluid design pressure. I wonder how to calculate the seating load as I don't...

How to calculate the seating loads in case of a direct metal to metal flanges? I have a rectangular flat face flange with a rectangular flat face blind. There is no gasket in between the flanges. I am trying to calculate the total bolting loads. Thanks for the help!

Hi all, Does any one know how to calculate the gasket seating load for a full face gasket? I don't think I allowed to use ASME VIII, Div 1 Appendix 2, since the gasket outer diameter is larger the bolts center diameter. Please note that I am new to the forum, and to pressure vessels design, so...
