I've got a flanged spec and in some instances there will be a requirement for an Insulation Bolt and Gasket set.
NEW bolting btw
The bolts are the standard inspec items but need an additional allowance to take account of the insulation washers, the normal washers (that the standard bolts don't have) and a gasket a couple of mm thicker than the standard. This may or may not cause the bolt length to jump up to the next size in the bolt length table
Now I don't want to go down the route of alternate flanges that call out a different BLRFARRA, along with an alternate XTRA value (although this would work)
Another possibility (and I'm thinking that this may be the best way right now) would be to have an alternate gasket with the thickness set to the thickness plus an allowance for the washers. This will work, will calculate the correct bolt length, however will also end up sticking a 1/2" seperation distance between flanges that may look a bit odd.
So I was wondering if the community had got any other methods of implementing a insulation gasket set that are a touch better than my two suggestions.
