Check out Taper-Lok high pressure compact flanges:

And, how about this big sub-sea check valve and more? :

In my former employ, we used Taper-Lok for some designs in approx. 7500 psi range. But wait. I am not a flange guru either.
We previously used lens-ring construction that was designed originally in 1950's by machine design engineers. All of those connectors are with threaded flanges, having straight threads. Gaskets are rings made from pipe material and make their seal against pipe ends. Each gasket and pipe end has a slightly different contour so there is a fine line of contact at assembly. Fittings are machined studded blocks of steel or stainless steel.
Some leakages occurred during shutdown and restart where lens-rings were used. This prompted us to look for a potentially better joint, and Taper-Lok proved to meet our needs. The Taper-Lok design also requires studded block tee and multi-port fittings.
There is an MSS document that now covers lens-ring:

MSS-65-1999, "High Pressure Chemical Industry Flanges and Threaded Stubs for
Use with Lens Gaskets," $60.00 US. It includes weld neck style and
threaded.

Al's flange array types graphic (
http://www.pipingdesign.com/drawings/flange_types_array.jpg ) shows a
few I've never heard of (no big surprise, I'm not a flange guru):
Anyone know more about these?
Websearches turn up some gasket info, but no actual flange details.
