Guess I'll be the first to post. I'm modeling some BOP's for a company. I have some 2D drafts of various blocks and valves in various sizes, but I lost my slide calculator for flange dims. does anyone have a good website to look these up? I have gotten by on woodcousa, but I am looking for a more user friendly site.
Other resources for connections dims would be appreciated. I'm going to keep looking and if I find some good ones I'll post my findings.
