Hi, We have a full titanium exchanger type BEM, with size ø1100mm and length 4500mm which we need to build. Our question: What is common practice for the backing gas for the final closing joint (shell-tubesheet) when all tubes are already installed? Filling the exchanger completly with Ar...

You can use XP mode within windows 7, provided by Microsoft (for free). Try to install it there. Sorry to hear that SW isn't willing to help, makes you think about the company....

Hi all, I have a high pressure exchanger with a "seal-welded diaphragm closure" for the channel cover. Reading some info about this gasket type made me wonder if I need to calculate the bolting torque/load like a self-energizing gasket or not (asme VIII div1 appendix2)...

Need to calculate a rectangular flange. Currently I use the HEI method, for full-face flanges. I've seen on the forum that others use: Marbec method called Nodal Circle Method BLACH Where can i find this methods? thanks.

Sorry for the unclearness...but it isn't a 2.13 type. You could see it as a regular loose type flange (type 2.4) but with the gasket outside the bolts & the flange is positioned in the middle of a pipe. The process fluid is around the flange and pipe.

Medium is around the flange, and the flange has tapped bolt holes. This is done for a "pull through floating head". Like a tema head type: "t".

The outer gasket is on the fluid side, the bolts on the ambient side. Indeed an unusual setup.

Hi, Don't think there is an exemption in the code but iven if there's one, you are pushing it beyond the limit. You are increasing your temperature (for how long?)with a factor 2? What kind of materials are you using, and how do you verify if the material will handle the temperature? Indeed by...

Hi, need to design a bolted flange with the gasket outside the boltcircle. It can't be a full face gasket, it is a flat metal jacketed gasket. Anyone?
