You would be better off getting your B7M bolts coated to avoid the pitting, a combination of electroless nickel and PTFE (i.e.: any of the proprietary coatings like Zylan). If you wanted overkill then you could get them hot-dip spun galvanized. It doesn't sound like your climate is that...
That is not normally a good solution. The design of the clamp (leak box) becomes very cumbersome, since you have to clear the OD of the flange and there is rarely enough space to use dished heads, so then the end plates must be flat, which means very thick, which means lots of distortion when...
Respectfully disagree with TGS4 on this one. FEA will get you a few things:
1) You can calculate the thermal transient response of the flange to the upset condition. This will give you the metal temperature of the flange during the upset. Depending on the size/class of the flange it will take...
The full name for flexible graphite used in gaskets, packing and the like is "Exfoliated Flexible Graphite". In other words they chemically expand the graphite structure (add voids) in order to get a product with some "squish". So in answer to your question, yes it does compress under...
Yes, I can confirm that as part of the effort to remove graphical approaches from the code and make it more computer program friendly, they curve fit the old equations with new ones. The accuracy of the new equations is within about 3% across to full range of the variables, so if you compare...
