Routing and asme vessel flanges on the finished welded tank... questions

[10mm]

Im new to routing for asme vessel flanges and pipe runs. Ive got the hang of it when the tanks already have the flanges welded on the tanks. My question is this.....when designing new tanks, what is the best way to add the flanges, olets and other fittings to the tank? They will be welded of course. If I have a tank with holes ready to have pipes/flanges welded to it, I cannot get the routing to work. Well, it inserts the flanges with the seal face against the pipe. Again, using routing after the tank is complete is easy going so far. Even the tutorials already have the finished tanks.


The attached pic in a tank that I punched the holes in, drew the pipe extension by extruding.....if I try to insert a flange using routing, the seal face is the face that mates up with the extruded extension pipe. I can TAB but it just flips it into the pipe. Disregard the note..I was playing with adding an axis.
I suppose I can just save as, and use the flanges as parts by removing the route points so I can use mates, but I want to do it the most practical way.

Thanks for any suggestions.

Are the flanges items you added or parts from the SW library?

They are from the routing piping library. Im not sure what im trying to do will work. I can insert it it, then flip the flange around and change the mates, but it still is not what I want. Again, all of the tutorials show finished tanks with all of the flanges and welded fittings already on them, so of course it is simple to drag and drop library parts. Maybe I cannot use the routing parts on the vessel the way I am attempting. Maybe I have to use actual parts to be welded to the tank instead. Another example is a simple hole in the vessel requires a class 3000 .75 npt threaded port to be welded on. I cannot find a way to add a routing part to the tank. Maybe routing is only to be used to plumb from vessel to vessel like the tutorials show. A few hairs have turned gray tonight.
If there is anyone that designs pressure vessels and also uses routing, I would like to know if you use the routed parts on the tank build or only for connecting to finished tanks. I can simply use the library parts as standard parts without routes on the tank itself. could be ive been trying to use routing in a way it was not designed for. This is how we learn I suppose.
